Gilligan’s Island information
Gilligan’s Island and Isla Ballena (Whale Island) are small mangrove islands off the tip of the Caña Gorda peninsula and are technically part of the dry forest reserve. Neither is too sandy, but both offer good sunbathing and passable snorkeling. The ambitious can reach these via kayak (rentals are available at Playa Caña Gorda, the Copamarina Beach Resort and Mary Lee's by the Sea) or you can catch a ferry in front of Restaurante San Jacinto every hour, barring bad weather.
If Gilligan’s is packed, pony up a couple more dollars to the captain and try the less-visited Ballena.
