SCUBA Diving with...


Aqua Action Dive Center

Known for its white beaches and turquoise waters, St. Thomas is home to the capital city of the U.S. Virgin Islands. National Geographic has rated St. Thomas among the top destinations for sailing, fishing, and SCUBA Diving.

Our focus is on custom-tailored dive trips and small, fun groups of people! All of our dives are led by one of our qualified and experienced Instructors or Dive Masters. They know the dive sites well and can point out the highlights of each site. Safety is our primary concern so you will receive a briefing before each dive so you will know what to expect while you are down below. All SCUBA equipment is included at no additional charge on all our trips (dive computers are available at an additional charge). Where we dive each day is determined by the composition of our divers, where they have been and/or want to go, and of course weather/sea conditions.

Our two-tank morning dive trips typically leaves at 9a (8:30a check-in) from our dive center at Secret Harbour Beach Resort.

Our afternoon dive trips can be either one- or two-tank dives upon request. We welcome snorkelers on our afternoon trips (for those divers with snorkelers in their group).
Our night dives, either by boat or from the shore, are available upon request (dive lights included).

Our staff is happy to accommodate private groups of up to 12 upon advanced request.

Our dive boat is a well maintained, USCG-Inspected 30ft Island Hopper designed for diving. It has easy entry into the water from the dive platform and a large ladder for coming back aboard. Our captains are U.S. Coast Guide licensed captains and our crew is random drug tested as part of our safety program. We offer fresh fruit and water on all of our trips. Our crew is always ready to assist you with your SCUBA equipment or any other of your diving needs.

Below is a sampling of some of our many dive sites...


Buck Island Wall (south side)

Buck Island wall can be one of two dive sites - Dive Flag Rock or Andres' Reef. This site is on the outside of Buck Island and is one of the deeper dives that we can do. We don't have the continental shelf drop offs that St. Croix has, but this wall is one of the nicer reefs we dive. There are pieces of machinery that were left in the 1960's and has been invaded by schools of blue and brown chromis, and the occasional eel or shark. The sand is in 60-70 ft of water and the top of the reef is in 30 feet for a nice multi-level dive. Sting rays and Eagle rays regularly cruise by as well.

Calf Rock (south side)

Calf Rock is right next to Cow Rock but it is a totally different dive site. Calf has lots of ledges to look under and crevices to peek into where you might be rewarded by the sight of a huge green moray or lobster (that won't fit into a normal cooking pot). There is a large field of soft corals and gorgonians that sway with the waves and huge stands of Elkhorn coral for the smaller fish to hide under. Fairy Basslets hang out under one large overhang by the dozens. The clear blue water and shallow depth at this site makes it a fantastic dive for photographers.

Carvel Rock (north side)

Carvel Rock was mistaken by some ancient seafarer as a ship who was so sure of his identification that he fired on the ‘ship.’ Upon approach to the site, you will see perhaps 100 yards of rocks that get larger from west to east.The mooring ball is on the south side of the largest rock and you always have to check the current, lest you wind up in Tortola. You’ll be treated to schools of bait fish and tarpon. Also to be seen are coral encrusted rock formations with interesting sponge structures, sea fans and tunicates.The north side is the deepest at 80 ft and the most fun, as you’re swimming through a canyon with almost totally vertical walls.

Congo Cay (north side)

This dive is at the western end, near the point, and the normal dive route takes you through canyons, around pinnacles and a sand chute that’s like an underwater ski jump down to 80 ft. For some of the dive, you’ll be treated to white sand and octocorals and at other aerial rocky encrusted coral makes up the terrain housing invertebrates galore. This site is great for fish watchers, who are treated to large schools of silversides, and even the possibility of sharks and bottlenose dolphins. More likely than not though, you’ll be seeing stingrays buried in the sand.

Cow Rock (south side)

Cow Rock has a series of swim-throughs with any number of cool critters residing in the crevices and a maximum depth of 45 feet. We regularly see lobsters clinging to the ceiling, brittle stars in between the rocks, and spotted drum in the swim-through. There's also the "Champagne Cork" - when there's enough wave action, this swim-through has the distinct feature of sucking you up spitting you out the top - just like a cork. Winding in and around the rocks you will be able to watch the waves breaking out over the tops of the formation. You'll see tarpon and usually a turtle or two.
