Fernandina Island (Punta Espinoza) On this morning we visited the youngest island, Fernandina. We disembarked in a dry landing for a one-mile walk. Fernandina has an amazing combination of barrenness with lots of wildlife. Having no introduced mammals, Fernandina has a very unique environment with the highest density of marine iguanas, sharing their island habitat with sea lions, sally-light foot crabs, and hawks. The lava terrain called for good walking shoes. After visiting this island we sailed along the Bolívar Channel, where we saw astonishing views of the Galápagos’ youngest volcanoes.
