On our last full day of our expedition on board National Geographic Gemini, we explored Bartholomew Island and Sullivan Bay on Santiago Island. We started early in the morning with a hike along the young lava flows of Sullivan Bay where we came across different kinds of lava, including the ropy pahoehoe and the irregular broken aa lava. After exploring this surreal landscape of black basaltic lava, we enjoyed some time on the beach while some of our Global Explorers took Zodiac driving lessons.

Later in the afternoon, we had our last snorkeling excursion and Zodiac rides around the coastline of Bartholomew where astonishing geological formations were the perfect backdrop for unique wildlife, including colorful fish, sea lions, penguins, Sally Lightfoot crabs, sea turtles, brown pelicans, and blue-footed boobies.

At the end of the day, we joined together with our guests, captain, and crew to give a toast to a fantastic week, and we enjoyed our photo slideshow for which all our guests contributed amazing images. The best reward after this incredible week was a wonderful feeling of friendship and shared excitement about all that we have shared in the Galapagos and the willingness to keep exploring and learning about unique places like this.
