We strolled through the lush highlands while our naturalist guide shared intriguing insights. Birds, including finches, often peck at algae or parasites growing on tortoise shells. Interestingly, they appear to leave a marker – possibly guano -to indicate to themselves or other birds that the area has already been picked clean.

A particularly captivating story the guide shared was about how the tortoises may have arrived on the islands. Some have been spotted floating at sea, buoyed by their shells. While saltwater ingestion typically proves fatal, a few may have survived the journey by avoiding it and eventually colonized the islands. Once here, they nested and established themselves over millennia.

Around the ranch, the scenery surprised us with its variety of fruit trees – papaya, passionfruit, and banana trees all grew nearby. These tropical plants thrive in the fertile volcanic soil of Santa Cruz, but we don’t see anything like them where we live.

As we left, a tortoise blocked the road—unhurried and unmoved by the vehicle. We had no choice but to drive around it, but it was kind of comical that it happened.

We felt immense gratitude to have experienced this cruise. The landscapes and wildlife felt remarkably undisturbed. Throughout our time on the islands, we did not see a single piece of litter. Nature here, however, is far from static. Our guide explained how El Niño and La Niña events can devastate local ecosystems. One such event wiped out over 90% of the coral. In ten years, climate shifts may again alter the islands in unpredictable ways.

Weather and ocean conditions were on our side. Due to the Coriolis effect, trade winds and ocean currents in the Galápagos usually flow from the southeast, driving the cool, nutrient-rich Humboldt Current from South America. These currents support a dense food web, influencing where wildlife can thrive and which islands are most biologically productive.

Our itinerary allowed us to see 12 out of the 15 recognized Galápagos species. We missed only the Galápagos albatross, flightless cormorant, and Santa Fe land iguana, which inhabit islands not included in our route. The sites on the islands weren’t arbitrarily chosen. The Galápagos National Park authorities control which vessels can visit which sites on which days, aiming to limit environmental impact and spread tourism evenly.

Each day followed a brisk schedule. Mornings often began at 6 or 7am with breakfast, followed by a midday break and lunch around 12pm. Dinner was served at 8pm. The tempo kept us moving constantly. By the end, we joked that we needed a vacation after the vacation.

Before heading home, we spent one final night in Quito before heading back. At the airport the next morning, we got to try chocolate from República del Cacao. This Ecuadorian company is a certified B Corporation, which means it meets high standards for social and environmental performance, accountability, and transparency. The chocolate itself was excellent, and is a testament to the country’s cacao heritage.

Often referred to as “Bird Island,” Genovesa supports immense colonies of seabirds, making it one of the most densely populated bird habitats in the Galápagos.

An Island Full of Birds

Genovesa is a sanctuary for seabirds, and nowhere is that more obvious than along the Prince Philip’s Steps trail. From the moment we landed, it felt like we were walking through a live aviary. Every few feet revealed different birds. First, we saw the Nazca boobies. These large, white seabirds with black-tipped wings and yellow eyes are one of the iconic “Big 15” species of the Galápagos. We saw both attentive parents and their fuzzy, down-covered chicks. Some of the chicks were already testing out their wings, flapping them clumsily as they stood in place.

The Nazca boobies didn’t seem to care about our presence. Some sat in the middle of the trail, forcing us to detour. They didn’t beg for food or try to flee. It was clear we were in their space. They looked at us with curiosity, as if evaluating our behaviour. One was even attracted to the bright coloured shoes of someone in our group. We joked at the bird was imprinting on them.

We also encountered several red-footed boobies up close (another Big 15 of the Galápagos ). Unlike the Nazca or blue-footed boobies, red-footed boobies are smaller and more agile in flight, using their dexterity to catch flying fish. They are also the only booby species in the Galápagos that nest in trees, thanks to their strong, grasping feet. Their nesting behaviour allows them to avoid the crowded ground-level colonies favoured by other species.

We also observed many great frigatebirds nesting. We had the fortunate of seeing the males with their red throat sacs inflated like balloons. However, we didn’t see the closely related magnificent frigatebird, which looks nearly identical but differs subtly in iridescent sheen and eye ring.

Further along the trail, we also spotted one of the iconic Darwin’s finches. This one was a brown finch, and though we knew it belonged to one of the local species, it was remarkably difficult to tell whether it was the small, medium, or large ground finch. These species differ primarily by the size and shape of their beaks, which have adapted to different types of seeds. In the field, even seasoned naturalists can find it tricky to differentiate them without observing feeding behaviour or using binoculars to compare subtle proportions. Genovesa is home to several of these species.

Spotting Rarities with a Naturalist’s Eye

We were lucky to be hiking with someone in our group who had spent decades as a professional naturalist. Her eye for detail helped us spot species we would have otherwise missed, including Galápagos doves nestled in a rocky crevice.

Our naturalist companion was able to spot the elusive short-eared owl. The short-eared owl is the only owl on Genovesa and is a daytime hunter, adapted to prey on storm petrels that nest in the island’s lava crevices. Seeing one is considered a highlight by bird enthusiasts.

She spotted this owl even when swarms of birds circled the crater. From a distance it looked like hundreds, maybe more.

I asked the guide how often people got pooped on by birds, and he said “all the time”.

How Did the Birds Get Here?

As we observed the vast diversity of birdlife on Genovesa, a natural question arose: how did all these birds get here in the first place? Genovesa, like all the Galápagos Islands, is of volcanic origin and has never been connected to any continent. That means every species had to arrive by sea or air. In the case of birds, it’s a mix of seabirds and land birds that flew in from the mainland over generations.

Seabirds like the Nazca booby, red-footed booby, and great frigatebird are strong fliers capable of covering vast distances over open ocean. They likely reached the archipelago by chance during migration or storms, eventually settling and breeding. Unlike land birds, which evolved in relative isolation after their ancestors arrived, many seabirds still travel between islands or even back to mainland South America during their lifetimes.

Land birds, such as the Galápagos dove and finches, probably arrived in earlier periods via rafting or wind dispersal and then adapted to island life. Their more limited range makes their evolution within the islands more distinct and well-documented.

Circumnavigating the Crater

After the hike, we boarded zodiacs for a ride around the inner edge of the caldera to get a better sense of its geologic origins. The steep, eroded walls of the crater revealed layers of volcanic tuff – compressed ash from past eruptions. In places, erosion had carved angular overhangs and caves. The crater rim is breached on one side, allowing the ocean to flood in and creating a calm anchorage for small vessels like ours.

Along the cliff face and the trees above, we continued to see more birds nesting. There were even some marine iguanas resting on rocks.

Courting Frigates and a Nap in the Sand

After lunch, we embarked on another short nature. Right as we began, we passed a sea lions sprawled out comfortably on the sand, fast asleep. They lay there without a care in the world, entirely unfazed by our presence. Many Galápagos animals are not concerned with human visitors, as long as we respect their space.

As we continued, we came across a group of nesting frigatebirds in full courtship display, with their bright red throat sacs fully inflated. They flapped their wings, made rattling calls, and shook their inflated sacs in dramatic fashion – all in an effort to catch the eye of a passing female. The sounds and motions were loud and theatrical.

Our guide mentioned research into their mating behaviours, including experiments where scientists altered the appearance of the sacs by painting them blue. Surprisingly, the colour change didn’t seem to affect female interest. In another case, a researcher punctured the sac to study healing – and it reportedly repaired itself within a few days. These stories underscored how much remains unknown about even the most visible species.

A Cloudy Snorkel and Playful Sea Lions

We ended the day with a snorkel along the rocky beach. Unfortunately, the water was too cloudy to see much underwater life. The coarse volcanic rocks made walking on the beach difficult; a few of us got small stones lodged in our flippers, which rubbed uncomfortably against our skin.

But the snorkelling wasn’t the real highlight. Back on shore, a group of sea lions came ashore and began to play. They chased one another, nipped each other’s flippers, rolled onto their backs, and flopped in and out of the surf in an endless loop of games. Their energy and antics entertained us for nearly twenty minutes.

One thing we noticed throughout the trip was the near absence of native terrestrial mammals or amphibians on the islands. Unlike birds or reptiles, which can fly or survive extended periods at sea, most land animals couldn’t make the crossing from the South American mainland. The Galápagos are over 900 kilometres from the coast, and animals unable to float, fly, or raft on vegetation simply never had the chance to colonize these remote islands.

Rábida: Brackish Lagoons and Flamingos

Our morning began before breakfast with a nature walk on Rábida Island, known for its deep red volcanic sands and its brackish lagoon. The lagoon is home to a small population of American flamingos, one of the Galápagos “Big 15” species. Our guides told us the odds of seeing them were low, so we considered ourselves fortunate to catch several wading gracefully in the shallows.

Among them was a juvenile with distinctive blue legs – a telltale sign of its age. We also got a good look at their black-tipped wings, which I never even knew existed. Flamingos, surprisingly strong fliers, most likely reached the Galápagos from mainland South America. One interesting fact the guides pointed out was how what looks like their knees are actually their ankles. They get their pink colour from their diet.

As we circled the lagoon, we passed a dead seal partially buried in the sand. It wasn’t clear what caused its death, but we didn’t speculate, but it was a stark reminder of the harsh realities of nature.

We returned to the ship for breakfast after our walk. One of the passengers had a health scare that morning; he collapsed on the ground as we were observing the flamingos due to low blood sugar. Thankfully, he recovered quickly. He was lucky that it didn’t happen when we were on more rugged terrain.

Glass-Bottom Boat Ride

After breakfast, we boarded a glass-bottom boat to observe marine life without getting wet. While it sounded ideal in theory, the reality proved less comfortable. The rocking of the boat while staring down made it easy to feel seasick.

Still, we managed to spot a vague silhouette of a shark, and a massive school of fish.

A sea turtle also came to say hi to us

Bartolomé: Snorkelling and Penguins

After lunch, we visited Bartolomé Island, a small but geologically striking islet famous for its towering volcanic spire, known as Pinnacle Rock. We began with a snorkelling session around the base of it.

After several days in the water, I started feeling more at ease, whereas before I never felt comfortable in the water, and this made the session much more enjoyable. We started to swim around the rock. The underwater scenery was rich with life: bright schools of fish, the occasional shark.

As I swam around the rock, I was busy looking around in the water, until I was suddenly startled by a sea lion sleeping near the surface. At first I panicked, but the sea lion paid us no mind. As it swam away, other snorkelers followed it.

Eventually we made it around the rock, and spotted some Galápagos penguins – another member of the “Big 15.” They stayed onshore this time, and we observed them resting on the rocks. It would have been school to swim in the water with them, but they didn’t jump in.

Later we found out that one snorkeller returned with rashes after being unknowingly stung by jellyfish (apparently from a few days ago, but didn’t the rashes didn’t appear immediately). None of us had realized jellyfish were in the water.

Volcanic Landscapes and Iconic Views

Later in the day, we hiked to the summit of Bartolomé to take in its famous view – the one often featured in postcards of the Galápagos. The trail was constructed with a special local hardwood known for its resistance to salt and corrosion. The path included many stairs, which made some hesitate, but was no problem for me. Funny thing is that the guide was panting harder than I was.

As we walked up, the black lava fields and stark, dry terrain stood in contrast to the more vegetated islands. Bartolomé is relatively barren, and is considered a geologically young island, having emerged from volcanic activity only a few hundred thousand years ago. Unlike older islands that have had time to accumulate soil and vegetation, Bartolomé’s surface is still largely exposed lava, ash, and tuff. Because it hasn’t developed significant plant cover or topsoil, its ecosystem remains in an early stage of ecological succession, providing a glimpse into what the earliest phases of island formation look like in the Galápagos.

Lava tubes scar the landscape – formed when the outer crust of a lava flow solidifies while the molten core continues to move. When the lava drains away, it leaves behind hollow tunnels. The ropey textures we saw on the ground were from lava flows, which cool into smooth, undulating surfaces.

The summit offers a sweeping view of Pinnacle Rock and the surrounding islets. From this vantage point, we could also see the contrast between the barren lava terrain of Bartolomé and the greener neighbouring islands like Santiago. The turquoise waters outlined the curves of the coastline, and we could spot sea birds gliding in the air currents.

After the hike, we took a short boat ride along the shoreline and spotted several more Galápagos penguins perched on the rocks. These curious birds seemed unfazed by our presence, occasionally flapping their wings or hopping between stones. We got to see a closer view compared to snorkeling.

Evening Science and Stargazing

Those who had opted out of the climb spent time with the ship’s naturalists collecting seawater samples. After dinner, they showed us the samples under a microscope. Even in just 3 mL of seawater, we saw fish eggs, miniscule shrimp-like creatures, and other microorganisms. Then I wondered how many of them I ingested from accidentally drinking the seawater while snorkeling.

Later that night, the skies cleared and we joined the guides on the top deck for a stargazing session. Thanks to our equatorial position, we could see both northern and southern constellations. The guide used a powerful laser pointer to trace the outlines of Scorpio, Libra, the Southern Cross, and even Ursa Major. They pointed out bright stars and planets like Antares, Alpha Centauri, and Beta Centauri. The clarity of the sky, with minimal light pollution, made the session feel so much richer than at a planetarium. This day was so much more than just wildlife. It combined also geology, and scientific curiosity.

Buccaneer Cove: Of Pirates, Gold, and Birds

One of our first stops was Buccaneer Cove, a site with a storied past. This cove on Santiago Island earned its name from the British pirates and privateers who are said to have used the area as a hideout in the 17th and 18th centuries. While records are murky, tales persist of pirates burying their treasures on the islands, with some modern locals claiming that sudden, unexplained wealth might be due to hidden gold discoveries. Some even say that treasure hunters still try their luck in the archipelago, but much of the island is off limits as part of the nature reserve.

We also learned an intriguing theory from one of our guides: a few pirates may have sketched the various finch species they encountered here. While the link to Darwin is speculative, it adds colour to the idea that knowledge of Galápagos finches existed before Darwin’s famous visit in 1835.

Reading the Rocks and Skies

The cliffs at Buccaneer Cove were a patchwork of rock layers, formed by successive volcanic events. The prominent soft rock here is called tuff – a light, porous stone made from compacted volcanic ash. Though it appears sturdy, it crumbles easily and is unsuitable for climbing – ironically not tough at all.

White splashes of dried seabird guano marked active nesting areas, and sure enough, we spotted swallow-tailed gulls resting nearby. These gulls have unusually large eyes adapted for night vision, allowing them to hunt squid and fish by moonlight. Their red eye-ring and soft, grey plumage made them easy to recognize as they perched calmly along the cliff edges.

Blue-footed boobies also dotted the cliffside. These birds are known for their vivid turquoise-blue feet. Despite being skilled divers and fliers, they move with an awkward, waddling gait on land that makes them oddly endearing. Their nesting behaviour, typically right on bare rock or sand, makes them easy to spot during the breeding season. Potential mates evaluate their “blueness” as it is an indicator of their health. A more intense blue coloration is a sign of better nutrition, health, and immune function.

A curious sea lion followed us part of the way, occasionally surfacing to watch. Like many animals in the Galápagos, it didn’t beg for food or flee at our approach. It simply seemed to want to know what we were doing.

As we continued along the coast, we passed two distinct natural formations. One was what our guide called a ‘prayer rock’—a rounded boulder that looked carefully placed, almost as if set down with intention. The smoothness of its surface and its balanced placement made it look like a deliberate monument, though entirely shaped by nature.

Nearby, the so-called ‘elephant rock’ resembled the head and trunk of an elephant carved naturally over time by wind and sea. Its resemblance was uncanny enough that even at a distance, the shape immediately stood out against the cliffside.

We also glimpsed rays moving below in loose formations, visible only as yellow blurs swimming across beneath the surface. At one point, we caught sight of a land iguana resting near a scrubby outcrop. Our guide noted how lucky we were to see it in that area, since land iguanas are not often spotted from this route and typically stay hidden in less accessible terrain.

Exploring the Cove by Kayak

Later, we had the chance to kayak around the cove. I had tandem kayaked before (I wasn’t good at it), but this time I figure out that successful tandem paddling isn’t about synchronization. Instead, the front paddler provides rhythm and power, while the rear paddler makes adjustments to keep the vessel on course through wind and wave. Synchronizing is actually the wrong thing to do because it doesn’t account for how waves push the boat.

The conditions were manageable, but we did witness somebody’s kayak flipping over.

Puerto Egas Snorkeling

Later, we snorkelled just offshore, where we saw schools of fish swimming around – almost like a National Geographic documentary.

I’m not a strong swimmer and felt pretty uncomfortable in the open water. Even with the flotation gear, it took some effort to push past the initial anxiety and focus on what was in front of me. Seeing the vibrant fish distracted me from the anxiety of being in the water.

I’ve been linking a few of the cruise photographer’s images here and there, but the above is a video of the snorkeling that really shows the vibrant sea life below.

Puerto Egas Nature Walk

In the afternoon, we arrived at Puerto Egas. The terrain here differs from other parts of the islands, combining coarse black lava formations with tide pools, beaches scattered with bleached coral fragments, and hardened ash deposits. Puerto Egas has its own unusual history. In the 1930s, businessman Hector Egas tried to establish a salt-mining operation and even constructed a few buildings here. The enterprise failed, and some locals believe the land itself resists commercial exploitation – a sort of “curse” for those trying to profit from nature rather than respect it.

These coral fragments, according to our guides, are remnants of ancient reefs pushed upward by tectonic forces and long since fossilized.

We were fortunate enough to spot a Galápagos hawk, one of the islands’ apex predators and part of the famed “Big 15” species to look out for. It was perched atop a tall, cylindrical structure that looked like an old salt silo – possibly a remnant of the failed salt-mining enterprise once attempted at Puerto Egas.

A pair of brown pelicans performed a coordinated dive nearby. It was the kind of behaviour that still feels dramatic when witnessed up close. Their timing was precise enough to make me wonder whether it was intentional coordination or just well-honed instinct.

We soon encountered lava lizards darting across our path. They blended so well with the ground that we nearly stepped on them more than once.

Eventually, we spotted a land iguana up close, grazing on nearby vegation. These large reptiles are also on the Big 15 list. The land iguana’s yellowish scales, thick limbs gave it a prehistoric presence.

On the trail, we notice trails in the sand that looked like they had been scratched with a stick. Our guide explained that these were land iguana tracks. By following one, we managed to actually spot another land iguana.

One of the more unusual features along the trail was a massive piece of fossilized coral, now hardened into stone. It had eroded into patterns that almost looked like brain tissue, a reminder that this part of the island was once under the sea. Unlike the scattered white fragments on the beach, this coral was intact.

Nearby, we also came across a striking rock formation full of jagged ridges and hollowed-out cavities. Our guide explained that this type of texture forms when lava cools rapidly and unevenly, sometimes trapping gas bubbles that burst and leave behind porous, twisted surfaces. The result looked almost sculptural—like the island was frozen mid-eruption

Later on we stumbled upon another uncommon sight: the skeleton of a marine iguana lying out in the open. It was a stark and silent example of how unforgiving natural selection can be – even here, in a place where animals appear fearless and abundant, survival is never guaranteed.

We also saw amusing sights like a sea lion snoozing on the rocks with a Sally lightfoot crab perched on its tail.

We also spotted a Galápagos mockingbird nearby. While less flashy than some of the other wildlife, they are still an important part of the evolutionary story Darwin would later popularize. Unlike some other mockingbird species, Galápagos mockingbirds are not brood parasites; they build and tend to their own nests.

While Darwin’s finches were less prominent than we anticipated, we did see several. It was a reminder that the islands offer so much more than a single narrative of evolution. Researchers today still visit the island to do research on evolution.

Our guide even made calls to drawing more attention from the surrounding birds, and mentioned that sometimes they may even land on people’s heads. When we asked if he was the only one who could make those calls, he smirked and confidently said yes.

Shipboard Dining

One thing worth mentioning is the food onboard. Meals were generally simple but thoughtfully prepared, with most ingredients sourced locally and sustainably from the islands. This makes sense too since tourism to the islands is a big part of their economy – if the animals here die out, it’s bad for the people too.

The food was also on the healthier side compared to other cruises – the fruit juice they had, while freshly squeezed lacked the flavour that we’re used to because they don’t add sugar. Due to strict biosecurity and transport regulations, only a limited selection of products are brought in from the mainland. For example, any steak has to be pre-cooked before shipping. Despite the constraints, the culinary team consistently managed to create a wide variety of dishes with what they had, adapting creatively.
