This has been a great day to observe reptiles and sea birds unique to the Galapagos. In the morning, we landed on South Plaza, where we spotted land iguanas, lava lizards, herons, swallowed tailed gulls and big male sea lions. We even spotted a hammer head shark from the cliffs of South Plaza.  In the afternoon, we went to snorkel and kayak around Santa Fe Island and later we landed on the island to explore a beautiful trail where we found giant cacti and the endemic Santa Fe land iguana.
