Six miles offshore, the view is beneath the waves. It’s Molasses Reef, the most accessible living coral reef in the United States, a slice of the Caribbean in the Florida Keys.
And it’s the main reason that John Pennekamp Coral Reef State Park exists.

About the Park
Established in 1960 to protect the reef – with onshore lands added after 1963 – it’s a 70-square-nautical-mile wonderland of corals, sponges, and tropical fish.
Molasses Reef is easily visited on a dive or snorkeling trip with a park-sanctioned outfitter or via glass-bottomed boat. See our images of a glass-bottomed boat trip below.
Not up for the open ocean? A small beach and snorkeling trail serve up a place to splash near shore.
The park offers landlubbers fun as well. Start off at the visitors’ center to see the saltwater aquariums, including a 30,000-gallon tank, that orient you to the sea life found on the reef.
Then explore the park’s nature trails to look for tree snails in the tropical hammock and (non-native but huge) iguanas hanging out in the mangrove forests.
A small native plant and butterfly garden adjoins the visitor center, with identified trees and plants.
You’ll find a picnic area on the north side of the parking area, close to the mangrove forest.
