Best Scuba Diving & Snorkeling in Key West

Local Experts' 10 Best Scuba Diving & Snorkeling

The Florida Keys are home to the only living barrier reef in the United States – meaning the reefs are found in the deeper waters further from the shore. They are abundant with marine life including hogfish, butterfly fish, blue tang, snapper, swordfish, and barracuda – not to mention some gnarly species of coral. Since the reefs are so far off the coast, you’re going to have to make a day of it on one of Key West’s copious snorkeling excursions. While many opt to join the masses on a catamaran for a booze and snorkeling trip, we recommend catching a ride on smaller vessels that offer a more personalized experience.  Divers also flock to the area to explore the Vandenberg and other modern shipwrecks and Spanish galleons, some of which the famous treasure hunter, Mel Fisher, made his fortune on. Adventure Watersports and Dive Key West are just two of the many outfits that offer dive trips. Here is our list of 10Best scuba diving and snorkeling companies to help you plan your underwater venture.

Sebago Watersports has it all: jet skiing, snorkeling, fishing, and kayaking – among other water adventures. The company also partners with the Schooner Appledore II, a traditional sailing vessel built by the Harvey Gamage Shipyard in South Bristol, Maine. From November through mid May the Appledore II is located in Key West, where it sails on day itineraries as well as its "Tall Ships and Tapas" sunset cruise featuring menu items like duck empanadas, crab sliders, Moroccan beef tenderloins, and some fruity sangria.

Local Expert tip: When the Appledore II leaves for Maine in May, Sebago continues to offer day cruises on its catamaran.

Danger Charters specializes in sunset cruises, including their signature Wind and Wine cruise. As the sun slips below the horizon, eight different fine wines, a selection of cheese, fresh fruits, beer, and hors d'oeuvres are served aboard the Danger Prize, a 65-foot schooner. The company also offers half and full-day snorkeling and kayak trips that are equally as memorable, plus a 10 percent discount for returning customers. Half-day tours include snacks and equipment and full day snorkeling also bundles a picnic lunch.

Local Expert tip: If you opt to book both tours in one day, go for the half-day tour. Several hours on the water can be exhausting by the time sunset rolls around.

Kayak Kings is a new venture by a veteran kayak guide, Alec James.

One of Florida's best kept secrets are the Dry Tortugas, a series of remote islands accessible by seaplane, private boat, or the Yankee Freedom II, a high-speed catamaran that departs from Key West. The Dry Tortugas are a protected national park with crystal-clear waters, spellbinding coral reefs, and the curious Fort Jefferson, which doubled as a prison during the Civil War. Tickets include the 70-mile, round-trip ride, breakfast and lunch, snorkeling rentals, and a 40-minute tour of Fort Jefferson on Garden Key. On board the vessel, guests will find amenities such as a galley, cash bar, air conditioning, cushioned seats, restrooms, and a souvenir shop.

Local Expert tip: The ride can be rough for those prone to sea sickness.

This company offers both fishing and diving charters, including trips to the pristine Marquesa Keys, a doughnut-shaped chain 25 miles west of Key West that consists of 10 uninhabited islands that are the only natural atoll in the Western Hemisphere. With numerous unmarked shipwrecks and clear waters, the diving here is nonpareil. Adventure Watersports Charter brings divers on a 10-hour day trip that includes four dives and lunch.

Local Expert tip: Don't be surprised if you spot Cuban refugee boats on the shores of the Marquesas. There are frequent landings on the islands.

A trip on Floridays includes an hour of snorkeling at the reef with a two-hour ride (there and back) on a gorgeous, intimate sailboat.

The crew is very informative and tells patrons exactly what to expect of the water conditions.

Lost Reef Adventures

Unlike some of the other snorkeling trips, Lost Reef gives guests two full hours of snorkeling at two different coral reefs. One day scuba dive "sample" courses, as well as more advance reef and wreck dives are offered as well. If the seas are rough during the dive, the staff will poll the divers and give them the option of diving or not. Up to 16 divers can travel on their 40-foot custom boat and a smaller, 26-foot vessel ferries parties of four to more remote sites east and west of the island.

Local Expert tip: If you visit during the winter, be aware that it is also the windy season and seas can be rough from time to time. Bring Dramamine.

Captain Seaweed, the owner's slightly spoiled dog, rides along on some dolphin-spotting voyages and will jump in and swim alongside these marine mammals. The owner, Donna, believes that Seaweed is convinced that these trips are "made for her" and that travelers just come along. Excursions combine snorkeling in the backwaters of Key West, dolphin watching, and eco-tours in the mangroves plus snacks on board the vessel "Bite Me."

Local Expert tip: Full charters area also available.
