Escambrón Marine Park

Escambrón Marine Park is a protected reef off the beach in San Juan, reached as a shore dive with no boat needed. The site runs 15 to 40 feet deep and is sheltered, with coral ledges, seagrass beds and old ruins on the bottom, plus plenty of fish. Dive schools use it for training, and snorkelers swim out on calm days. Visibility is best on calm mornings, before the trade-wind chop picks up, and the site can be dived year-round.

The shallow depth and short swim from shore keep the logistics simple.
