Today the National Geographic Endeavour II anchored in front of one the most volcanic islands in the archipelago, known for its amazing landscapes and colors: Bartolome. We started the day with a morning hike, and later we offered snorkeling and the glass-bottom boat outings. In the afternoon, we repositioned to Sombrero Chino Island, where we offered another snorkel outing and coastal explorations via Zodiacs, to look for the Galapagos penguin.
