Gilligan's Island Guánica, PR
one of several mangrove cays – the Cayos de Caña Gorda – that form part of the Guánica Biosphere Reserve


The municipality of Guánica is full of natural wonders ready to be discovered by visitors to Puerto Rico’s southwestern coast. Among these is Gilligan’s Island, a perfect place to feel like a castaway. This “island” is actually one of several mangrove cays – the Cayos de Caña Gorda – that are in turn part of the Guánica Biosphere Reserve.

Venturing into the grotto involves a short ferry ride: visitors board the “lancha de Gilligan” on the Guánica shore. The welcome sign reveals Gilligan’s original name, Cayo Aurora. Although these small cays are uninhabited, the crowds can get large on weekends and holidays, so it’s best not to expect the isolation its “TV show”-referencing name suggests.

Gilligan’s does represent quite a different experience for beachgoers. Stretches of sand are scarce, so visitors mainly leave their scant supplies on the shore or hanging from a mangrove, then proceed to wade on the gentle, clear, shallow waters. The hours seem to melt away in this relaxing setting, so do make sure to bring appropriate protection for the sun.

Popular activities here include snorkeling and kayaking.
