Located 30 miles south of Santa Cruz, Floreana is the sixth largest of the islands. A one-time colony, today only a handful of people live here. A relaxing and interesting place to visit, wildlife concentration is not as great as other neighbouring islands but it has some of the most interesting human history. At Post Office Bay 19th century whalers kept a wooden barrel that served as post office so that mail could be picked up and delivered to their destination.
