Admiralty Dive Center Dive Sites


Navy Barges: With ribs reaching upward like the very skeleton of an extinct dinosaur the Navy Barges provide a home for an array of tropical fish and colorful coral. The 45-foot depth allows plenty of bottom time for your voyage into the past.

Cartanzar Sr: A derelict freighter that was moved from Charlotte Amalie harbor and set near Buck Island Cove, was broken into three parts by hurricane Hugo and rolled into 45 feet of blue water.

Now a home to countless tropical fish, eels, rays and occasional sharks, it's a great dive for the novice to experienced diver.

East Wind: Corporate yacht that fell victim to a squall and ended up on the rocks in the late 60s.

Time and hurricanes have reaped their toll and have scattered the remains among the colorful reef, with swim-throughs, a large population of tropical fish, lobsters, occasional sharks and turtles, making this 50-foot dive a beautiful and exciting dive.

Miss Opportunity: A 300-foot plus hospital ship that was used as an office complex now lies 3/4 upside down in 90+ feet. Home to a huge Jew fish, and other pelagics, make this an adrenaline-pumping dive. (Advanced dive)

W.I.T. Shoal: The premier dive of the Virgin Islands. 400+ foot freighter, laying upright in 90+ feet of crystal blue water. Home for large Jew fish, snappers, roaming pelagics, turtles and tropicals. A photographer's dream, as light penetrates the holds and passage ways. Penetrate the ship by entering the smoke stack openings, enter the very soul of the W.I.T. Shoal. (Advanced dive)

Other Wrecks: Grain barge, W.I.T. Concrete, Aaron's barge, Kennedy and Tow boat.

With so many beautiful reefs to choose from, we will always choose the best site for conditions and diver ability. The majority of our reefs are in the 40-foot to 60-foot range. Sea conditions and diver experience are always a consideration for your fun and safety. Requests are always considered.

Flat Cay: A playground for tropical fish and slow flying sting rays. Depths from 17 to 70 feet make this an ideal dive site for experienced divers to snorkelers.

Dry Rocks: Grottos, overhangs and crystal blue water make this an ideal habitat for tons of tropical, pelagic and reef fish. Occasional turtles and sharks add to the wonderment of this 30-foot to 70-foot dive.

Stone Face: Large coral-encrusted fingers starting at 50+ feet, reaching shoreward to 10 feet make this dive seem like a walk in the park. Enjoy the wildlife as you slowly weave through the rows of coral.

Sprat Point: Picture frame swim throughs, billows of coral, make this a wonderful dive. With the average depth of 40 feet, it's a memorable experience.

Easter Reef: A sea mound laying in 80 feet, is home to a bevy of sea life, from the tiny bassets to a shy Jew fish. Often times you may be greeted by turtles, free-swimming eels, eagle rays, sharks and all the wonderment mother nature has to offer. (Advanced dive)

Aqua Action Dive Center 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.

French Cap (south side)
French Cap is an uninhabited island approximately 6 miles south of St. Thomas. Because it is unprotected, the seas must be relatively calm before we even THINK about going there. In 90 feet of water this is one of the few places you will see Black Durgeons & huge schools of Sennet fish.

Lobsters are in abundance here, as are any number of the larger game fish, hog fish & permit, just to name a few. We usually do both dives on French Cap, with a shallower dive to 60 feet on the northwest side of the island. On the second dive you will be treated to a swim-through that has a nice cathedral ceiling you can actually surface into.

Blue Island Divers
Blue Island Divers are the first operation on St. Thomas to use research to discover may wrecks previously unknown to St. Thomas dive operators. This untapped SCUBA Diving has opened up St. Thomas diving and is forging Blue Island Divers as the wreck-central of the Caribbean.

Their new wreck sites range in depth for the new diver as well as the advanced or technical diver. Many sites are of an ideal depth for Nitrox. All of this is, of course, is as well as offering pristine reefs for the reef enthusiasts and conservationists.

Blue Island Divers is located near Admiralty Dive Center (see listings above) so you can see the dive sites and descriptions on their listings.

Dive In! Dive Sites

Carval Rock
20-70 feet
About four miles northeast of St. John, about halfway between St. John and St. Thomas, is Carval Rock, a dive area visited by dive operators from both islands, weather permitting. Even on a good day, the current resulting from tidal flow from Pillsbury Sound can be substantial, thereby classifying it as an advanced dive.

In good conditions, this is a site worth experiencing. You have a little bit of everything - dramatic rock formations, coral gardens and a fish community that includes open-water species. Anywhere from 20 to 80 feet, divers are bound to find a host of surprises.

Congo Cay
29-90 feet - Novice with instructor or divemaster Boat
About three miles northeast of St. John is Congo Cay, a dive area visited by dive operators from both St. Thomas and St. John. It is part of a series of small islets or cays that extend between the two large islands.

Located near Carval Rock, it is a 30-minute boat ride from St. John and only slightly longer from St. Thomas.

Congo Cay is distinguished by its reefs, rocks and boulders. Between 30 and 60 feet, divers will find the most marine activity. A series of seamounts off the west end of the island provides a vibrantly colored tapestry, ideal for photographers.

You will find some of the best photo opportunities between 20 and 40 feet. The northern side of the Cay plunges to 75 feet, where lobsters hide among large boulders and the chances of spotting eagle rays, tarpon, and even manta rays are good.

This is also a great spot to see a diverse array of invertebrates that make their home on the rocks. Orange tubastrea carpets the rock faces and, at night, explodes in full bloom to create a spectacular tangerine-hued garden.

Grass Cay
55 feet max - Novice with instructor or divemaster Boat
Although Grass Cay is located only 10 minutes by boat from the dock at Stouffer Grand Beach Hotel on St. Thomas, the site attracts dive operators from St. John as well.

The dive area, which is situated in a sandy anchorage on the south side of Grass Cay, is one of those places to which divers like to return.

The dive begins fairly shallow at about 20 feet. From 20 to 50 feet, the terrain is a variegated carpet of densely packed coral that conceals a plethora of surprises at a distance.

But upon closer observation, the coral heads reveal an abundance of invertebrate life from dainty Christmas tree worms and featherdusters to bristle worms and tunicates.

Large sea fans sway almost imperceptibly because there is generally little or no current, which also contributes to the above average visibility. There is no shortage, of fish life either. Chromis, hamlets, grunts, creole wrasse, trunk fish, and large hermit crabs inhabit this territory.

Barracuda cruise by regularly. In the summertime, turtle encounters are not unusual. This dive site has some of the best hard coral formations in the area.

Tunnels at Thatch Cay
45 feet - Novice with instructor or divernaster Boat
Just off the northwest point of Thatch Cay is a dive site considered by some divers to be the "piece de resistance" of dive sites - Tunnels of Thatch Cay.

A relatively shallow dive, averaging about 40 feet, it is an easy but wonderfully varied underwater experience to be enjoyed by all levels of divers. It is recommended that novices be accompanied by a divernaster or instructor only because the surge can be difficult to negotiate at times, especially for less experienced individuals.

The high level of ambient light and the diversity and dramatic sculpturing of the terrain make this an excellent dive for underwater photography. For fish portraits or wide-angle photography, you will find tarpon, especially during the summer months, a host of tropical fish, expansive clouds of silversides, and interesting coral formations including the highly photogenic pillar coral.

Wreck of the Major General Rogers
42 to 62 feet - Intermediate Boat
Located almost directly in front of one of the most delightful resorts in St. Thomas, Stouffers Grand Beach Resort, is the wreck of the Major General Rogers. A 120-foot, steel-hulled, self-propelled auxiliary Coast Guard vessel.

Marine life is abundant and flourishing on this wreck. Tube sponges, hard and soft corals, purple tunicates, curling hydroids and striped bristleworms provide splashes of color all over the gray hulk. Within the confines of her open cargo holds and around the hull, pompano, Spanish hogfish, and schools of grunts and snapper circle rhythmically. Curious barracuda hover silently nearby.

About 200 feet from the General Rogers is a second wreck. This vessel, which was sunk at about the same time as the General Rogers is an overturned self-propelled Coast Guard barge.

It is not recommended for divers to swim inside because the interior is very cramped and silty. A line attaches the two wrecks and they can be explored on the same dive. However, the General Rogers has so much to offer that it is likely divers will expend their bottom time without ever leaving this wreck.

Ledges of Little St. James
15-40 feet - Novice Boat
Located on the southwest side of the island is a unusual dive site with huge, deeply indented ledges and prolific tropical marine life. It is ideal for the novice diver because it is well-protected from currents or surge and offers a maximum depth of only 40 feet.

The most interesting features of the dive can be experienced to the fullest in depths from 15 to 25 feet. Within this shallow range, you will find several exquisite stands of pillar coral including one that majestically looms at 8 to 10 feet tall.

The deep undercuts for which the dive site derives its name reveal a variegated patchwork of encrusting corals. Nearby boulders are similarly encrusted with coral from which colorful Christmas tree worms and fragile featherdusters timidly emerge and retract. Beware of the mustard brown fire coral and the occasional black sea urchin.

There is no shortage of marine activity. If you have the patience of a saint, a circling juvenile spotted drum may permit you to take a photo. Porcupine fish, lobster, schooling grunts, big lizardfish, as well as queen and gray angels are among the permanent residents in the area.

This is also a superb night dive. The water is generally calm. The color is vibrant. You will find it quite easy to find wonderful creatures all over the site. This is a must for macro photography.

Cow and Calf Rocks
25-40 feet - Novice with instructor or divemaster Boat
If you head off the southeast end of St. Thomas, you will come upon some rocks that barely break the surface of the water. As legend goes, the larger of the rocks were mistakenly identified by a nearsighted mariner as migrating humpback whales, a cow and her calf.

At the west end of the "Cow," there is an H-shaped network of coral tunnels that is roomy enough to accommodate two divers. Inside the tunnels, with the aide of a dive light, you'll see the rough-hewn walls transform into a kaleidoscope of dazzling colors as the red encrusting corals, yellow sponges and orange tubastrea come to life.

Even though this particular site has little silt to stir up, be careful not to kick up the bottom so divers who swim through after you can enjoy the experience as well.

This is an ideal spot for the curious diver. With a maximum depth around 40 feet, you are unlikely to run out nooks and crannies to explore before you run out of bottom time.

This is not a particularly deep dive, but it is generally recommended as an intermediate dive due to the surge conditions. For divers with some experience, this is simply an inconvenience.

The Wreck of the Cartanser Senior
25-35 feet - Novice Boat
According to various versions of Cartanser Senior's demise, the 190-foot steel-hulled freighter had served to transport goods during World War II. Later it operated as an inter-island freighter, and rumor has it that its cargo was not altogether legal.

It was eventually deserted by its captain and crew for reasons that may or may not be a mystery. Abandoned and unmanned, it began to take on water and ultimately sunk in the Gregerie Channel in St. Thomas harbor.

As the Corps of Engineers prepared to destroy the vessel, which presented a clear navigational hazard, an underwater picket line of divers successfully intervened to preserve their "dive site." Cartanser Senior was relocated to the west side of Buck Island. A few years later, Hurricane Alan saw to it that the wreck was relocated once again.

This dive is ideal for a first wreck dive or for the novice diver. Situated in a well-protected cove, there are no heavy currents or surge on this wreck. Visibility is generally good so divers can view a large portion of the wreck at one time. It is no wonder that Cartanser Senior is one of the most popular dives in St. Thomas.

Homer's Scuba and Snorkel Dive Sites
Hull Bay has some of the best shore and kayak diving on St Thomas and can put most of the best boat diving sites to shame on the south side of the island where most of the diving is done.

The depths range anywhere from 30 to 60 feet and no one has ever been disappointed. The reefs are in better shape than most because no one ever dives here except Homer. The diving on the north side is dictated by the weather and the summer months are the best.

Red Hook Dive Center Dive Sites

North - Atlantic Exposure

Arches & Tunnels of Thatch Cay
Arches and Tunnels is one of the most requested sites in the area due to its amazing bottom topography consisting of, you guessed it, a series of arches and tunnels. Swim under the Welcome Arch and begin a fantastic adventure packed full of swim-throughs, silversides, tarpon, and a colorful variety of corals and fish.

The rock formations are the highlight of the dive but there is no shortage of marine life as you navigate through the Haunted House and Dog Leg. Located on the Northwest end of Thatch Cay, this site may not be dive able certain times of year due to weather conditions.

Jaws has a scary name but don't worry, you will be laughing when you hear how it came about. A nice combination of low laying reef, rock formations, crevices, and a beautiful Cathedral. Another great place to see an abundance of tarpon, silversides, and often nurse sharks.

Congo Cay
Congo Cay is probably our most frequently dived site on the North side due to its very colorful scenery, rock formations, and larger fish. This dive is adjacent to a little deeper water and offers the chance of seeing big stuff like eagle rays, reef sharks, and occasionally dolphins.

There is a large sand flat bordering the are which attracts sting rays and nurse sharks. Located on the west end of Congo Cay, you will have a nice down island view into the British Virgin islands.

Carval Rock
Carval Rock is another of St Thomas Island's most beautiful dive sites because of the large variety of sea life that are always present. Named after a 17th century fast fighting ship, and located just northeast of Lovongo Cay and east of Congo Cay, this spectacular dive site rewards divers with a magnificent view of nature's underwater environment.

From rock formations, swim throughs and wide variety of corals and fish at depths of 15-80 feett this always proves to be a popular request. This is a popular dive site for those tarpon lovers who want to get a great photo, up close and personal.

Pillsbury Sound

Mingo Passage
Mingo Passage is a very colorful, shallow reef with a higher concentration of small fish. This site is also a great place to find eels, lobsters, and sometimes octopus.

The reef becomes more dense throughout the dive and is complemented by large black sea fans and huge barrel sponges. Make sure to look around during the dive so you don't miss spotted eagle rays or schools of fish passing by.

Mingo Bay
Mingo Bay is a sloping reef that tapers down to a vast sand flat. The sand flat is anything but void of sea life... garden eels, upside down jelly fish, conch, and hermit crabs are frequently present.

In addition, there are mounds or islands of reef that are very colorful and create a perfect place for fish and other marine life to take shelter. The upper part of the reef is a shallow shelf and creates a perfect environment to have a close encounter with either a green or hawksbill turtle.

Squidville is another great sloping reef that offers an easy entry with a sandy bottom and then progresses into a beautiful reef packed with fish. One never knows what to expect here. Sting rays, turtles, all sizes of fish, lobsters and eels are common. This is a common site for our Discover Scuba divers but is a great dive for all levels of experience.

Grass Cay
Grass Cay is a nice combination of large coral heads, sloping reef, and mounds on the sand flat. Navigate around the mounds out on the sandy area, swim around the coral heads, and then work your way along the sloping reef for a diverse bottom topography.

Coral Gardens
Coral Gardens is a maze of large coral heads to navigate around. This colorful, dense reef is a great place to see barracuda, eagle rays, and larger fish.

Wreck of the Major General Rogers
The wreck of the Major General Rogers is one of the only wreck dives we have on this part of the island. This wreck is encrusted in growth, creates a great hiding place for marine life and even has some areas to swim through. Due to its location, this site may not be dive able certain times due to weather or current.

South - Caribbean Exposure

Cow Rock
Cow Rock, often mentioned with its counterpart Calf Rock, is one of the most popular sites on the South side. Consisting of a rocky bottom topography that is covered in colorful growth, these natural formations create several swim throughs that attract many divers.

In addition, this site and others in the area fall within the protected waters of a marine preserve. An abundance of fish, turtles, lobsters, rays, and sharks can be seen here.

Calf Rock
Calf Rock, located right next to Cow Rock, is a separate dive and does not have swim through's This site has a lengthy ledge that creates a great hiding place for crabs, lobsters, and nurse sharks. The similar colorful, rocky bottom has some shallow areas that host beautiful examples of elkhorn, stag horn and pillar corals.

Stragglers Reef
Stragglers Reef is a combination of healthy reef and large boulders that are covered in life. Start this dive by making your way out to the reef in search of snappers, grouper, lobster condos, and eels! As the tour continues, prepare to navigate in between large cracks and crevices filled with colorful tropical fish.

Ledges of Little St. James
Ledges of Little St. James is just what it sounds like, a series of ledges, overhangs, and undercuts. This creates a wonderful habitat for schools of fish to hide in! Surrounded by a colorful, low-laying reef, this site is also a good place to encounter lobster, turtles, nurse sharks, and octopus. Ledges is also a perfect place for snorkeling.

Rays Rise
Rays Rise is a fringe reef that is adjacent to a large sandy area. Dive along the edge keeping an eye out for large southern stingrays, garden eels and queen conch in the sand. This site has rocky areas that provide a great habitat for lobster and eels.

Castle Reef
Castle Reef is one of our best dive site secrets... it's not marked with a mooring buoy but we will get you there if the weather is right. This is a colorful finger reef that is surrounded by sand flats. Also within the marine preserve, we frequently see rays, eels, octopus, turtles, large nurse sharks and lots of lobsters.

Fish Bowl
Fish Bowl is our farthest site to the west, near Buck Island and also one of our deeper dives. This site is a vast spread of coral heads in the deeper area and a sloping perimeter that creates a bowl effect.

The upper edges of the site have larger coral heads and are busy with smaller tropical fish and colorful growth. Keep an eye out for the Atlantis Submarine so you can wave and take pictures of the reciprocating passengers.
