Today we enjoyed the opportunity to explore the uplands of Santa Cruz, one of the largest islands of the Galápagos. The humid zone offers perfect foraging grounds for the giant tortoise; in order to find the tortoises, we travelled by bus from the north of the island to the southern side. We found large numbers of tortoises on the privately owned El Manzanillo Ranch. After a delicious lunch, we returned to our ship and weighed anchor. We had reports that Wolf Volcano, located on Isabela Island, was still active! We navigated for a few hours until we reached the coast nearest to the eruption site; from there, we admired a beautiful red glow against the dark night. What an amazing opportunity to admire the forces of nature that produced these magnificent islands!

National Geographic Endeavour II
Isabela Island
Navigation brought us to the largest island in the Galapagos Archipelago, Isabela. Holding half of all land mass in the Galapagos, it has a diverse selection of ecosystems that we were able to visit. Urvina Bay was geologically uplifted in the 1950’s, taking two square kilometers of seafloor that was thrust upward, in certain areas up to four meters out of the water. Intertidal species were stranded inland, and we walked upon this area. Galapagos giant tortoises and land iguanas were found on our trail, and we were surrounded by Darwin finches and Galapagos mockingbirds. The afternoon brought us to Tagus Cove where we explored the surrounding waters, encountering Galapagos penguins and Pacific green sea turtles swimming among the kayakers and snorkelers. As the sun dipped below the horizon, adventurous hikers took a fast-paced hike to enjoy an incredible view of Darwin Lake and the immense island of Isabela.
