From the guide
Three to start with

Crash Boat
Heads up: on 18 August 2025 part of the historic pier at Crash Boat collapsed in hurricane swell and the Municipality of Aguadilla closed the pier structure indefinitely, so check its status before diving.
Shore diveto 55 ft (17 m)Aguadilla & Northwest
El Natural
Heads up: El Natural in Aguadilla has no sign or parking lot, and the shore entry crosses jagged rock, so water shoes are essential and a local operator advises going with a guide to find the right entry.
Shore dive30–80 ft (9–24 m)Aguadilla & Northwest
Escambrón
Heads up: the swim-throughs are overhead environments, and a local operator warns of surge in the open water.
