Diving in St. Thomas is easy and accessible, and offers an array of experiences for everyone. And because the U.S. Virgin Islands is a territory of the United States, you’ll enjoy the added safety of diving within U.S. waters. This means that all dive boats are inspected by the U.S. Coast Guard and captains are USCG-certified.

More than 500 species of fish, 40 types of coral and hundreds of invertebrates inhabit the water. Vibrant blue tang, silvery horse-eye jacks, queen triggerfish, spiny Caribbean lobster, spotted eagle rays, Creole wrasses, and cleaner gobies are just a sampling of the marine life populating the underwater terrain. As the sun sets, octopuses, sea horses and moray eels make their appearance. Hawksbill, green, and leatherback turtles, call the USVI home and can be seen on many a dive. Lucky vacationers may even witness turtles hatching at one of the many turtle-nesting grounds.

Most dive operators teach a full range of PADI (Professional Association of Diving Instructors) and NAUI (National Association of Underwater Instructors) courses from beginner scuba to instructor training. Specialty courses such as underwater photography, peak buoyancy, wreck, drift and boat diving are also available through many operators. Training for those with physical disabilities is available at several dive outlets.

St. Thomas is surrounded by some of the Caribbean’s healthiest reefs, and it offers more than a dozen shipwrecks. Here are a few of the local dive operators’ favorite sites:

Navy Barges

The twin barges originally housed men’s quarters during WWII. After the war, they were demolished and sunk, creating the ideal habitat for marine life. Trumpetfish, big angelfish, feather dusters and Christmas tree worms hang topside, while squirrelfish, bigeyes and channel clinging crabs hide out in the crawl spaces.

Wit Shoal II

Situated southwest of the St. Thomas airport, this former Navy tank-landing ship sunk in 1985. Now a thriving artificial reef, the ship is home to yellowtail snapper, barracuda and grouper which patrol its five decks. Brilliant orange cup coral and sea fans are among the amazing coral communities.

Cow & Calf

Located off the southeast coast of St. Thomas, the two largest rocks that break the surface are said to look like whales—a cow and her calf. Cow & Calf boasts dramatic ledges, wide canyons and large caves.

Tunnels of Thatch

The black rock arches and lava tubes are indicative of the volcanic origin of the islands. The tunnels are a part of Thatch Cay, an island northwest of St. Thomas. Bright cup corals and sponges are visible from the moment of entry. Divers wind their way through a series of tunnels, past big boulders and gorgonian patches actually swimming though the island. Butterflyfish, parrotfish and trumpetfish spend their days in the gorgonians, while tarpon pursue schools of silversides. Moray eels and spiny lobsters are regular residents of the reef.

Coki Beach

Adjacent to the popular Coral World Ocean Park, Coki Beach is home to two fringing reefs located 50 yards offshore and separated by a sandy flat. Beginner and advanced divers enter the pool-like conditions to find bar jacks, grunts, yellow headed jawfish and cleaner shrimp. An occasional stingray or turtle can be seen passing by.
