John Pennekamp Coral Reef
Overview
John Pennekamp Coral Reef State Park stands as a landmark destination for travelers seeking the natural beauty of the Florida Keys. Established in 1963 as the first undersea park in the United States, it spans approximately 70 nautical square miles of diverse ecosystems. For RVers, this park offers a unique opportunity to stay within a protected marine sanctuary, where the focus is entirely on the vibrant coral reefs and the tropical wildlife that inhabits the surrounding mangroves and Atlantic waters.
Location & Surroundings
Located at Mile Marker 102.5 in Key Largo, the park serves as the gateway to the Florida Keys. The landscape is a lush mix of tropical hammocks and winding mangrove forests that open up to the crystal-clear waters of the Atlantic Ocean. Its position provides a serene escape from the busier commercial stretches of the highway, allowing guests to wake up to the sounds of tropical birds and the gentle rustle of palm fronds in the salt breeze.
Amenities & Park Features
The campground at Pennekamp is designed for convenience while maintaining a rustic, natural feel. It features 47 campsites that accommodate both RVs and tents. Each site is equipped with full hookups, including water, sewer, and 30/50-amp electrical service. Travelers will find gravel pads, picnic tables, and grills at every site. On-site facilities include clean restrooms with hot showers, a laundry room, and a large saltwater aquarium within the visitor center that showcases the local marine life.
Nearby Attractions & Things to Do
The primary draw here is what lies beneath the surface. Visitors can book glass-bottom boat tours or join snorkeling and scuba diving excursions to see the famous Christ of the Abyss statue. For those who prefer to stay on top of the water, the park offers rentals for kayaks and canoes to explore the intricate mangrove trails. Fishing is permitted in designated areas, and the nearby town of Key Largo offers world-class seafood dining and local boutiques just a short drive away.
Who This Park Is Best For
This park is ideal for active outdoor enthusiasts and families who want to immerse themselves in water-based activities. If you enjoy snorkeling, kayaking, or educational nature programs, you will feel right at home here. It is particularly well-suited for RVers who prefer a state park atmosphere over a commercial resort, favoring natural conservation and direct access to the ocean over luxury amenities like swimming pools or clubhouses.

What makes this place special? The "Diving Capital of the World" Key Largo is the first and largest of the Florida Keys, renowned worldwide for its incredible underwater ecosystem. This location is a paradise for marine enthusiasts, home to the John Pennekamp Coral Reef State Park—the first underwater park in the U.S.—and key dive sites like the Molasses Reef and the impressive USS Spiegel Grove shipwreck. Beyond the water, its unique location offers access to the tropical hardwood forests of Dagny Johnson Key Largo Hammocks State Park. It’s the perfect blend of seaside relaxation and serious ocean adventure. Tips for Fellow Local Guides: For Divers/Snorkelers: Mention that the Christ of the Abyss statue is a must-see. The shallow reefs are excellent for beginners and snorkelers, while certified divers can explore the deeper wrecks. Dining: Key Largo is famous for its sunset views. Advise visitors to find a bay-side restaurant (Gulf side) around sunset for the best dining experience. Fresh seafood is a given, especially the local catch-of-the-day. Accessibility: As the closest Key to the mainland, it's easily accessible from Miami (approx. 1-2 hour drive). The Overseas Highway (US-1) is the main route. Note that public beaches are limited, so water activities usually start from marinas or parks.

John Pennekamp State Park is an absolute gem in the Florida Keys! This place is so cool, with stunning natural beauty that's perfect for sightseeing. We loved exploring the trails that wind through the lush mangroves—it's like stepping into a tropical adventure. There's a convenient boat ramp for easy access to the water, plus clean showers and bathrooms that make it super family-friendly. A food truck onsite kept us fueled with tasty bites, and the beach area is ideal for relaxing or dipping your toes in. Kayaking here was a highlight, gliding through the clear waters spotting marine life, and the walking paths are great for a leisurely stroll. It's the perfect spot to spend an entire day immersed in nature—highly recommend! 5 stars!

The Park was such a great experience and the perfect start to our Florida Keys road trip. We rented a double kayak and, even without any experience or navigation skills, we were able to follow the recommended route easily on our own. Everyone was incredibly friendly and helpful, so we felt comfortable and safe the entire time. It’s a wonderful place to explore independently and to enjoy the beautiful nature. Just make sure to bring sunscreen and mosquito spray – there can be quite a few mosquitoes in the mangroves, but luckily the park’s own shop has you covered if you forget anything!
