The Ledges

The Ledges of Little St. James

Depth: 20–60 ft | Beginner | Staff Favorite

Dramatic limestone overhangs and deep “shelves” create a stunning visual playground for underwater photographers and nature lovers alike. Sunlight filters through the crevices, illuminating the white sand below and creating a mesmerizing play of light on the reef. It’s a primary resting spot for Nurse Sharks, moray eels, and Green Sea Turtles.
If you are looking for a scuba dive crash course (DSD), this is the perfect site to start your journey in calm, clear water.

“Steph’s Tip: Look closely under the deep ledges—it’s the favorite nap spot for our local Hawksbill turtles!”
Cow and Calf Rocks

Cow and Calf Rocks

Depth: 25–45 ft | All Levels | Protected Park

Explore a vast network of wide swim-through tunnels and “The Cathedral,” a stunning archway where light streams through to the reef fish below. This site is famous for its intricate rock formations that shelter an abundance of marine life, from schooling French Grunts to elusive Caribbean Reef Squid. This is a must-see for certified divers looking for incredible photos in a protected marine park.

“Tommy’s Take: The ‘Champagne Cork’ swim-through is an absolute blast—it gently pops you right back out onto the reef!”
Fish Rock

Fish Rock

Depth: 15-30 ft | Beginner | Relaxed

Fish Rock is a dramatic pinnacle dive that rises from the depths, acting as a magnet for diverse marine life. The site is constantly visited by large schools of tropical fish, creating a shimmering curtain of color. The swirling currents often bring large Southern Stingrays and patrolling Tarpon, offering divers a front-row seat to the local food chain. This relaxed site is a frequent request for those booking exclusive private charters.

“Mich’s Note: Keep your eyes on the blue—you never know when an eagle ray will cruise by!”
Cabrita Point

Cabrita Point

Depth: 30–70 ft | Drift Potential | Vibrant Reef

Located on the eastern tip of St. Thomas, this sloping reef offers a dynamic dive experience. It is densely covered in massive Sea Fans, colorful Plume Corals, and sponges that create a vivid underwater garden. The topography features a notable drop-off that feels like floating in space, making it a biodiversity hotspot where you’ll often find Spotted Eagle Rays gracefully cruising the current along the ledge.

“Zach’s Tip: The current here is often just right for a lazy drift dive—let the ocean do the work!”
Packet Rock

Packet Rock

Depth: 40–60 ft | Wreck Site | History Dive

Dive into the past at the 1816 wreck site of the HMS Warwick. This site is a captivating blend of natural reef and historical artifact. Even after two centuries, you can still find remnants of the ship’s cargo embedded in the limestone reef, including broken pottery shards and roofing tiles. It’s a gentle, thought-provoking dive that connects divers to the maritime history of the Virgin Islands, all while surrounded by modern schooling fish.

“Crew Favorite: It’s like a literal underwater treasure hunt. Don’t touch, but do look closely!”
Coral Bowl

Coral Bowl (Shark Bowl)

Depth: 30–80 ft | Natural Amphitheater

The Coral Bowl is a breathtaking natural amphitheater, ringed by tiers of mature hard and soft corals. The structure creates a dramatic circular “bowl” that provides a protected habitat for marine life. Because of its unique geography, it is a premier location for spotting larger marine animals, including Caribbean Reef Sharks and large Southern Stingrays that often congregate in the sandy center to feed. The verticality and scale of this site make it feel truly expansive.

“Abby’s Take: The verticality here is stunning—it’s like a three-story house made of coral!”
Fish Sticks

Fish Sticks

Depth: 40–80 ft | Drift Style Dive

Named for its unique, pillar-like rock formations that extend vertically from the ocean floor, Fish Sticks offers an incredible drift diving experience. As the currents carry you gently along the reef wall, you’ll pass through huge schools of Creole Wrasse, snapper, and hunting Jacks. The wall is alive with dense patches of healthy coral polyps, making it one of the most visually stunning drift dives in the St. Thomas area.

“Ben’s Hint: The ‘sticks’ aren’t just rocks—they’re home to some of the healthiest coral polyps in the islands.”
Stragglers

Stragglers

Depth: 30–60 ft | Intermediate | Staff Favorite

Stragglers features a series of volcanic “fingers” that stretch out from the coastline into the deep blue. The dramatic landscape gives the site a wild, adventurous feeling, separating it from the typical shallow reefs. It’s an intermediate site where we frequently spot larger pelagics like Spotted Eagle Rays and curious Reef Squid patrolling the edge of the reef. The open-water feel makes for an unforgettable excursion.

“David’s Note: Make sure to compliment the eagle rays on their spots—they love the attention!”
The Cartanza

The Cartanza Senora

Depth: 35–60 ft | WWII Wreck | All Levels

This 190-foot WWII freighter is one of the most iconic wrecks in the USVI. Resting in three distinct sections on the sandy bottom, the wreck has become a sanctuary for marine life. The structure provides ample shelter for Sea Turtles that often rest on the deck, and hidden crevices where Octopuses reside. It’s an accessible, beautiful wreck dive that offers plenty of exploration opportunities for all experience levels.

“Lewis’s Tip: Exploring the rusted ribs feels like a real treasure hunt—keep your light handy!”
Dog Island

Dog Island

Depth: 25–50 ft | Marine Sanctuary

Dog Island is a pristine marine sanctuary that showcases the Caribbean at its best. Because of its protected status, the coral growth here is exceptionally healthy, featuring large stands of Elkhorn coral and vast gardens of swaying sea fans. This high level of biodiversity makes it a reliable site for spotting Hawksbill Turtles and enjoying exceptionally clear, calm conditions. It’s an ideal location for a relaxed, nature-focused dive.

“Duke’s Tip: Even though I’m the shop dog and don’t dive, I hear this island is named after my ancestors—so you know it’s good!”
Dive Flag Rock

Dive Flag Rock

Depth: 30–60 ft | Intermediate | Cleaning Station

Named for the distinct jagged rock that breaks the surface like a beacon, this site is a bustling underwater highway. It serves as a major natural cleaning station where Hawksbill Turtles pause for a scrub from cleaner shrimp, and Spotted Eagle Rays frequently cruise the corridor. The intersection of reef and open water creates constant activity, making it an incredible spot to visit on a private charter where you have maximum bottom time to watch the marine traffic.

“Crew Note: Keep a sharp eye on the ‘cleaning stations’—you’ll see tiny wrasse and shrimp working hard on the bigger fish!”
