Dive-site story
Escambrón Marine Park is San Juan's central shore-diving site. Natural rock breakwaters and artificial reefs shelter a quiet inner lagoon that gives way to an outer reef track, where divers encounter submerged columns known locally as the Atlantis ruins. Navigation remains simple across a seabed of sand, scattered coral heads, seagrass patches, and concrete reef balls.

Location
Use the map to plan with your operator and confirm the exact entry point on the day.
Seasonality
Summer offers the calmest seas and clearest water; winter swells stir up sediment outside the cove.
