Santiago and Bartolome Islands, 5/30/2025, National Geographic Gemini
Aboard the
National Geographic Gemini
Galápagos
Today we explored Sullivan Bay, in Santiago Island, and Bartolome Island. In the morning we explored a relatively new lava flow, where we learned about the geology of the Galapagos during the early stages of these volcanic islands. In the afternoon we explored Bartolome Island, where we enjoyed unique moments spotting animals such as Galapagos penguins, sea lions, blue-footed boobies, and many sea creatures during our snorkeling activities. We finished the day celebrating the wonderful expedition we just had on board National Geographic Gemini.
Javier grew up on Santa Cruz island where his grandparents first arrived in the 1940´s. Veritable pioneers, his grandparents settled in the highlands where they found a place to raise their children.
We started the day with excitement as we landed on the beautiful, pristine coast of Isla Genovesa - a true birder’s dream. Along the sandy beaches and steep cliffs of Darwin Bay, we were surrounded by an incredible array of birdlife. Frigatebirds soared closely overhead with their red pouches on full display, while Nazca and blue-footed boobies nested along the rocky ledges. Swallow-tailed gulls called out as we walked past. In the distance, we saw the stoic and elusive short-eared owl. The island was alive with color, sound, and constant movement. Between our excursions to Isla Genovesa, we snorkeled near Prince Philip’s Steps and discovered a vibrant world beneath the waves. Schools of fish swirled around us, a fur seal turned in the water as if dancing on cue, and sea lions relaxed nearby. As our last snorkeling adventure came to a close, we spotted a sea turtle resting calmly in a crevice. As the sun retreated into the sky on our last return to National Geographic Endeavor II, we reflected on the sheer magnitude of what we witnessed on our last full day. Isla Genovesa, like the other islands, gave us a connection to a sacred world. The harmony between land, sea, and sky reminded us how deeply interconnected, vital, and fragile these ecosystems are. Watching birds tend to their nests and marine life swim effortlessly, we were struck by how little space there is between wonder and reverence. We recognized that our journey wasn’t just about observing unique wildlife, it was about feeling part of something grander and beautifully ancient.
Today’s expedition began with a morning visit to the dramatic Sullivan Bay lava field on Santiago Island. Guests explored the intricate patterns of the pāhoehoe lava flow, observing its rope-like formations and scattered pioneer plant life—offering a vivid lesson in volcanic geology and ecological succession. In the afternoon, we hiked to the Bartolomé viewpoint, where we were rewarded with one of the most iconic landscapes in the Galápagos. From the summit, the stunning contrast of Pinnacle Rock, turquoise waters, and surrounding volcanic islands reflected the archipelago’s raw beauty and geological history.
Sadly, our expedition aboard National Geographic Gemini is nearing its end. Our day began with a hike at the base of towering cliffs. A steep ascent led us to a plateau of a palo santo forest, sparse and otherworldly. Almost immediately, we were surrounded by red-footed boobies nesting in low trees and Nazca boobies on the ground. A highlight was spotting a short-eared owl perched silently among a lava crevice, camouflaged and hunting storm petrels. The calls of frigatebirds rang in the air, with their inflated red pouches on full display in a mating show. After our hike we enjoyed water activities, such as kayaking along the cliffs and snorkeling. In the late afternoon, we landed on the coral sand beach of Darwin Bay. Guests enjoyed a relaxing stroll along the shoreline bordered by mangroves and nesting bird colonies. The presence of swallow-tailed gulls, lava herons, and marine iguanas provided excellent photo opportunities.
