Floreana is one of the most southerly islands in the Galapagos archipelago and was the first island to be settled by humans. At Punta Cormorant there is a large, brackish lagoon inhabited by one of the largest flamingo populations in the Galapagos Islands. There is excellent snorkelling at Devil’s Crown, a sunken cinder cone with numerous reef fishes inside and larger fish outside the crater. Post Office Bay is mainly of historical interest with its wooden barrel ‘post office’ where visitors can leave postcards and collect and send cards left by previous visitors.
