The third trail, The Mangrove Trail, takes you through the swamps and mangroves native to the park. 

Many people enjoy taking tours on the glass bottom boats, kayaking, canoeing, and paddleboarding. SCUBA diving, snorkeling, and swimming are popular ways to get acquainted with the park’s life under the sea. Fishing is allowed in the park but only in specified areas. Camping and boating are popular in the park with bathrooms/showers and washers/dryers.

The park is home to more than 600 species of fish, 70 types of coral, manatees, crocodiles, dozens of species of birds, and lizards. The John Pennekamp Coral Reef State Park is open year-round from 8 am until sunset. The entrance fee is $8.00 per car plus 50 cents per person.

Six miles off the Key Largo coast is the USS Spiegel Grove Wreck. This popular diving site was intentionally sunk in 2002 as an artificial reef. It is one of the largest ships to ever be scuttled for this purpose. Almost instantly, fish and corals started making the ship their new home — creating a whole new ecosystem, making an incredible diving experience. You must have an advanced open water certification or higher to dive the reef.

There are several dive trips that you can book to take you out to the wreck, where it is requested that you take a special class on how to dive the Spiegel Grove Wreck. Because of its enormous size, nearly two football fields long, there are special instructions for divers. If you plan to see the entire ship, you’ll need to schedule about 4 dives!
