Española Island is the southeasternmost island in the archipelago. It is slowly but surely losing the battle against the elements, after drifting over 200 kilometers from its birthplace. As it has moved on top of the Nazca tectonic plate, it has effectively lost all influence of the Galapagos Hotspot, the life force that fuels most volcanic activity in this group of islands. Despite being presently only a fraction of its original size, it is still home to vast numbers of sea birds, as well as an endemic species of mockingbird and lava lizard, unique not only to the archipelago but specific to Española. We explored the northeastern end of the island at Gardner Bay and nearby Gardner Islet during the morning, and the western end at Suarez Point during the afternoon.

National Geographic Endeavour II
Bartolomé and Sombrero Chino Islands
Warm ocean air and a colorful sunrise met us as we approached Bartolomé. Guests traveled by foot or Zodiac to experience the compacted ash landscape. On our first snorkeling excursion, we swam with diving penguins and sea creatures like whitetip and blacktip sharks, rays, and parrotfish. On the next snorkeling opportunity, we enjoyed seeing even more fish and sea stars! After lunch, we were back on the Zodiac for a third snorkeling opportunity. We dove in by Sombrero Chino. We spotted whitetip sharks, a school of fish, sea lions, pufferfish, and more. We ended the day by circumnavigating Sombrero Chino on Zodiac. We spotted more penguins. The community spirit that has developed over the week was evident as a Zodiac of guests serenaded Sarah on her birthday! Traveling to the Galapagos has made the world feel small. We have found common ground with guests and staff and made connections between our actions back home and the conservation of this beautiful archipelago.
