A classic shore dive at Crash Boat Beach in Aguadilla, where a collapsed military pier has become an artificial reef and the surrounding sand and seagrass keep the dive feeling varied rather than fixed in one lane. The site works for relaxed snorkeling or scuba, with coral on the pilings, fish around the structure, and open room for macro hunting in the nearby flats. It is the kind of dive that rewards easy buoyancy, a slow pace, and time spent looking both under the pier and away from it. Clear water and simple shore access make it an easy day dive when conditions are calm.
