San Cristobal Island is one of the oldest Galapagos Islands where the flora and fauna has taken over and been exposed to the elements. This island is no longer an active volcano as it sits in the southeastern end of the archipelago. Now this island is slowly deteriorating to the point that it will go back into the ocean. The Galapagos Islands are formed because of the activity of a stationary “hot spot” that lays on the northwestern end of the archipelago under the Nazca Plate. This tectonic plate slides towards the southeast and as it goes by the “hot spot” area it produces enormous volcanoes that when they emerge out of the ocean become islands. The islands that had been carried away from the “hot spot” area then became extinct volcanoes.

National Geographic Endeavour II
Genovesa Island
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.
