John Pennekamp Coral Reef State Park

John Pennekamp Coral Reef State Park in Key Largo is the United States’ first underwater park, protecting a vibrant portion of the Florida Keys reef tract. Visitors come for snorkeling and diving among coral formations, tropical fish, and shipwrecks, or to view the reef via glass‑bottom boat. Kayaking and paddleboarding through mangrove trails offer quieter wildlife encounters, while sandy beaches and picnic areas suit relaxed days. The on-site visitor center features aquariums and reef exhibits that add context to marine conservation. It’s an ideal stop for travelers seeking accessible, family-friendly reef experiences without venturing far offshore.
