Water Adventures: Snorkeling, Diving & Boat Tours

John Pennekamp Coral Reef State Park: America’s First Underwater Preserve

John Pennekamp Coral Reef State Park protects a massive underwater ecosystem full of living coral, colorful fish, and sea turtles. Visitors can swim right off the sand at Cannon Beach, take a boat trip out to deeper reefs like Molasses Reef, or rent a kayak to paddle through the coastal mangrove creeks.

Arriving before 8:30 AM helps visitors beat the daytime crowds, secure easy parking, and get on the water before the afternoon wind stirs up the sea. Morning boat tours offer the clearest visibility for spotting marine life. Day-use entry is $8 per vehicle (2–8 people) plus a 50¢ Monroe County surcharge per person; single-occupant vehicles pay $4.50; pedestrians and cyclists pay $2.50 (fees include the surcharge).

Christ of the Abyss: How to See the Famous Underwater Statue

Christ of the Abyss is a 9-foot bronze statue resting in about 55–60 feet (17 meters) of water at Dry Rocks reef; snorkelers can see it from the surface on calm days, but divers get the closest view. Because the water is shallow enough in parts, snorkelers and scuba divers can view the famous sculpture easily from the surface or below.

Booking a morning tour with local operators gives visitors the calmest sea conditions and brightest sunlight for taking underwater photos. Waterproof phone housings or simple action cameras capture the best pictures when the morning light shines straight down through the clear water.

Mangrove Kayak & Paddleboard Eco-Tours

Mangrove tunnels are narrow, shaded water paths winding through dense red mangrove trees along the upper keys. Paddling through these quiet creeks near mile markers 98 to 102 lets visitors spot juvenile nurse sharks, upside-down jellyfish, and wading birds in their natural habitat.

Renting a kayak from Hidden Key Marina costs between $40 and $70 for a half-day adventure. Going at dawn provides the smoothest water surface, cooler morning temperatures, and the highest chance of seeing wild manatees feeding near the shoreline.

Glass-Bottom Boat & Sandbar Tours (For Non-Swimmers & Families)

The Key Largo Princess Glass Bottom Boat takes passengers on a cruise to the edge of the living reef without requiring anyone to get wet. Large glass viewing panels set into the floor of the boat let families watch parrotfish, stingrays, and yellowtail snapper swim below.

Sandbar adventure tours take smaller groups out to shallow knee-deep water flats for relaxed swimming and sunbathing. These trips work great for families with young children who want a fun boat ride and safe wading spots.

Plan Your Trip: Maps, Mile Markers & Getting Around

The Florida Keys use a mile marker system starting with Mile Marker 127 near the mainland boundary down to Mile Marker 0 in Key West. Key Largo spans roughly from Mile Marker 110 (or MM 127 at the mainland boundary) down to Mile Marker 90 along the Overseas Highway (US-1). John Pennekamp State Park sits around mile marker 102.5, while Snook’s Bayside rests near mile marker 99.4, and the REEF center operates near mile marker 98.3. Renting a car remains the easiest way to travel between mile markers, as public bus transit is limited and ride-share options can be sparse on the upper keys.
