Snorkeling at Dry Tortugas
Dive into crystal-clear waters teeming with sea turtles, tropical fish, and pristine coral reefs surrounding America's most remote national park.
Why Dry Tortugas Has the Best Snorkeling in Florida
Seventy miles from the nearest landmass means zero runoff, zero pollution, and water so clear you can see 100 feet to the bottom. The reefs here look like the Caribbean did 50 years ago—untouched, vibrant, and teeming with life.
Unlike the heavily-trafficked reefs of the Florida Keys, Dry Tortugas remains pristine thanks to its remote location and national park protections. Only a few hundred visitors experience these waters each day, compared to thousands at more accessible sites.
"The snorkeling at Dry Tortugas is hands-down the best I've experienced in the continental United States. The visibility and marine life rival anything in the Caribbean."
Top Snorkeling Spots
From beginner-friendly shallows to advanced drift snorkels, Dry Tortugas offers something for every skill level.
Fort Jefferson Moat Wall
The iconic moat wall offers protected waters perfect for beginners. Spot sergeant majors, parrotfish, and the occasional nurse shark along the historic brick structure.
Loggerhead Key
The second-largest island in the Dry Tortugas, Loggerhead Key offers pristine reefs and the historic lighthouse. Excellent for sea turtle sightings and diverse coral formations.
Little Africa Reef
Only accessible by private boat, this pristine patch reef system features brain corals, elkhorn formations, and abundant marine life rarely seen by visitors.
South Coaling Dock Ruins
Historic underwater ruins attract massive schools of fish. This is the best spot for sea turtle encounters—they're often seen grazing on seagrass nearby.
Duck Key
Shallow protected waters ideal for beginners and wildlife observation. A peaceful spot away from the main fort with excellent visibility.
Garden Key Beaches
Easy shore entry with calm conditions perfect for first-time snorkelers. Walk right in from the beach and start exploring.
Marine Life You'll Encounter
The waters of Dry Tortugas are home to an incredible diversity of marine species protected within the national park.
Sea Turtles
Loggerhead, green, and hawksbill turtles are regularly spotted grazing on seagrass beds.
Tropical Fish
Angelfish, parrotfish, grouper, goliath grouper, snapper, and over 300 other species call these reefs home.
Coral Reefs
Brain coral, staghorn, elkhorn, and star coral formations create underwater gardens.
Nurse Sharks
Docile nurse sharks rest under ledges during the day—exciting to spot but completely harmless.
Swimming with Sea Turtles
Dry Tortugas is one of the best places in Florida to encounter sea turtles in their natural habitat. Three species—loggerhead, green, and hawksbill—nest on the islands and forage in the surrounding waters.
Unlike crowded snorkel spots where turtles have learned to avoid humans, the turtles at Dry Tortugas are remarkably calm and curious. With a respectful distance, you can often observe them for several minutes as they graze on seagrass or surface to breathe.
Green turtles are the most commonly spotted, often seen munching on seagrass in the shallows near Garden Key. Early morning snorkels offer the best chance for close encounters before the day heats up.
Snorkeling Tips for Dry Tortugas
Make the most of your underwater adventure with these expert tips from our captains.
Go Early Morning
The calmest, clearest conditions are typically before 10 AM. Plus, marine life is most active in the cooler morning hours.
Use Reef-Safe Sunscreen
Regular sunscreen damages coral. Choose mineral-based, reef-safe formulas or wear a rash guard for sun protection.
Float, Don't Kick
Gentle movements disturb less sediment and won't startle fish. Let the current carry you and save energy for longer sessions.
Look Under Ledges
Nurse sharks, lobsters, and moray eels often hide in crevices. Shine a light (but don't touch!) to spot hidden creatures.
Stay Hydrated
Saltwater and sun are dehydrating. Drink plenty of water between snorkel sessions, even if you don't feel thirsty.
Don't Touch Anything
Coral is fragile and some marine life can sting. Observe from a distance and never stand on the reef.
