The City of Washington was a steam ship built in 1877 and sunk in Key Largo’s Elbow Reef in 1917. It lies at a depth of 25 feet (minimum depth 16ft and max depth 34ft) and is easily reachable with a 30 minutes boat ride. The shipwreck is relatively shallow, making it also one of the most popular snorkeling spots on Key Largo.

The Duane Shipwreck was a U.S. Coast Guard Cutter built in 1936 and sunk on November 27, 1987 in the Molasses Reef. The wreck lies upright on a sandy bottom in 120 feet of water one mile south of Key Largo.

Besides amazing wreck dives, you can also dive spectacular reefs in Key Largo. The most famous one being the Molasses reef.

Molasses Reef, located off Key Largo, is one of the most popular dive spots in the Florida Keys. This vibrant reef boasts an array of colorful corals and sponges that attract diverse marine life such as parrotfish, angelfish, and nurse sharks.

Islamorada: Paradise for Beginner Divers and Snorkelers

Islamorada is home to French Reef, a popular dive site with a variety of coral formations and marine life, including nurse sharks and spotted stingrays.

If you are travelling with a snorkeling partner, of if you are a newly certified diver, Islamorada is definitely for you. Most diving spots in Islamorada have a starting depth between 10 to 15 feet, making it ideal for shallow recreational diving.

Despite the shallow depths, Islamorada also offers a wealth of reefs and shipwrecks. Among the most famous dive spots, you will find the Alexander Barge and the Alligator Reef.

The Alexander Barge is an amaznig wreck dive at a depth from 80 to 105 feet. This shipwreck was deliberately sunk in 1984 to form an artificial reef, that was complemented a year later by the remains of the old Whale Harbor Bridge. Nowadays, both hard and soft corals have started forming on the artificial reef and plenty of marine life has started inhabiting it. Among others, you will be able to spot snappers, grunts, jack fish, barracudas, lobsters, and large groupers.

Key West is home to the Dry Tortugas National Park, which boasts some of the most pristine and untouched coral reefs in the world.

The park is only accessible by boat or seaplane, but the journey (2 hours by private speedboat or 40 minutes by seaplane) is worth it to see the abundant marine life, including green moray eels, sea fans, and large schools of fish.

If you are planning on diving the Tortugas National Park, you will need to book a private dive trip as the seaplane is not an option and the ferry will not allow you to carry scuba tanks. The only dive shop that is currently organizing dive trips to the Dry Tortugas National Park is the Finz Dive Center.

The day trip might be a bit expensive, however note that the diving at Dry Tortugas National Park is way superior than in any other place in the Florida Keys. This is one of the very few places where you will spot 30” hogfish regularly, black groupers and huge Goliath groupers.

Lower Keys

The Lower Keys offer a variety of dive spots, including Looe Key, an underwater paradise with a diverse array of marine life, and the Adolphus Busch, an artificial reef created by sinking a former shrimp boat.

Marathon

Marathon is home to Sombrero Reef, a shallow coral reef system that is perfect for beginner divers and snorkelers. The reef is teeming with colorful fish and sea life, including parrotfish, angelfish, and sea turtles.

Sombrero, a mostly shallow dive, is also a perfect spot for snorkeling. If you are interested in a snorkeling trip, i recommend checking out The Starfish. They offer daily snorkeling tours to Sombrero.
