Site details

Triumph Reef is a shallow patch reef on the outer reef line at the southeastern edge of Biscayne National Park, north of Pacific Reef Light. Like the park's other named outer reefs (Long, Ajax, Pacific), it is boat-access only and protected under National Park rules, with healthy hard corals, sea fans and abundant reef fish in clear, warm water. Its shallow crown suits snorkelers while the surrounding slopes give easy novice scuba profiles.
