Welcome to John Pennekamp Coral Reef State Park

Key Largo’s John Pennekamp Coral Reef State Park is one of a kind, offering an amazing glimpse into the underwater world.

Renowned for being the country’s first undersea park, John Pennekamp Coral Reef State Park encompasses an impressive 70 nautical square miles. While many visitors view the park’s colorful coral reefs and teeming marine life on a glass-bottom boat tour, one can get an even closer look by scuba diving or snorkeling.


Canoeing and kayaking through the park's waters are popular activities; fishing is permitted in designated areas.

Visitors can also enjoy walking on short trails through tropical hammocks, picnicking or swimming at the beach. The visitor center features several large saltwater aquariums filled with sea creatures, and nature videos are shown in its theater. Full-facility and youth/group campsites are available.

Dive in to explore Florida’s Coral Reef at the park.

Sergeant Majors at John Pennekamp

Sergeant majors are one of the many fish you can find at John Pennekamp's reefs - and one of the most feisty. Their name comes from their coloration rather than their attitude: They have prominent, vertical black bars on their sides, reminiscent of the insignia of a military sergeant major.

Artesian Well at Pennekamp

An uncommon sight in Florida, John Pennekamp is home to an extremely deep well that serves as an integral part of the park's ecosystem. The well has created a pond that drains into a small creek, which in turn flows into the marina. The brackish-water creek is perfect habitat for the mangroves growing there.
