This day we were visiting Sombrero Chino Islet in the morning, a spectacular place due to its geology. We had fun during our Zodiac ride along the coastal area, not only observing the amazing shape of Sombrero Chino Islet, but also Santiago Island with its dark lava flow. We were happy to see the Galapagos penguin and several of our guests enjoyed kayaking in this area. Afterwards we went snorkeling in the crystal clear water which was full of life. There was colorful fish, white tipped reef sharks and Galapagos penguins! In the afternoon the National Geographic Islander was repositioned toward Sullivan Bay where we hiked on a lava flow dated back to 1897. It was a great place to learn about the geology of the Islands, how life ends and how begins once again!
