About This Beach

History & Background+

Cayo Aurora (Gilligan's Island) is located in Guánica municipality on Puerto Rico's south coast. This mangrove cay sits within a protected coastal ecosystem where shallow channels and sheltered waters create ideal conditions for marine biodiversity. The surrounding mangrove forests provide critical habitat for fish, crustaceans, and seabirds.

The beach offers clear waters with excellent underwater visibility and diverse marine life, making it a premier snorkeling destination. Unlike the northern coast's Atlantic-facing exposure, Guánica's southern location provides calmer, more protected waters. The municipality has deep historical roots in Puerto Rico's maritime heritage, and Cayo Aurora reflects the ongoing relationship between coastal communities and the sea.

Whether visited by local families on weekends or travelers discovering the area, this secluded cay carries the character of its pristine surroundings and remains largely undeveloped due to its remote boat-access-only status.
