Contadora one of the most visited of the Pearl Islands, and gets its name because it was a counting house for pearls. This island is only about a 750 acres in size, but it features 13 spectacular beaches and 5 coral reefs surrounding it that offer incredible snorkeling opportunities. One of Contadora's beaches, Playa de las Suecas, is the only official clothing-optional beach of Central America. Several roads cross the island, which can be walked around in about an hour. Excursions to other less inhabited islands are available. Contadora is a 15 minute plane ride or a two hour ferry ride from Panama City. You can't fly directly from Tocumen International Airport, but domestic flights depart daily from Albrook airport, which is about a 30 minute drive from Tocumen.
