Best Dive Sites at Green Turtle Cay

The diving around Green Turtle Cay offers real variety, from shallow coral gardens and dramatic cavern systems to historic wrecks and active restoration sites.

Depth: 25 to 60 ft | Level: Open Water+

Coral Caverns

The signature dive site. Towering coral formations create dramatic swim-throughs, cathedral-like arches, and deep cuts where nurse sharks rest and massive groupers cruise. The topography is unlike anything else in the Abacos: walls of coral rising from sandy channels, with light filtering through overhead gaps. It’s right next to the coral nursery, making it a natural pairing for a two-tank dive.

Depth: 30 to 50 ft | Level: Advanced Open Water

The Catacombs

A labyrinth of interconnected tunnels and overhangs in a massive reef structure. Schools of tarpon hang in the darker recesses, while lobster and moray eels tuck into crevices. This site rewards slow exploration; every nook reveals something new. A favorite for underwater photography.

Depth: 30 to 45 ft | Level: Advanced Open Water

USS Adirondack (Civil War Wreck)

A United States Navy steam frigate that sank in 1862 during the American Civil War. Now encrusted with coral and home to a thriving ecosystem of reef fish, the wreck sits in relatively shallow water with good visibility. It’s one of the most historically significant dive sites in The Bahamas, and a magnet for sharks and large pelagics.

Depth: 10 to 25 ft | Level: All Levels

Reef Rescue Network Coral Nursery

More than a dive site: a working coral restoration project. Underwater “trees” hold hundreds of staghorn and elkhorn coral fragments growing to outplanting size. On RRN Expeditions, divers harvest corals from the nursery and plant them onto nearby reef sites under scientific guidance. Even as a recreational dive, seeing the nursery in action is striking.

Depth: 5 to 15 ft | Snorkeling

Turtle Lagoon

A sheltered area where wild green turtles and hawksbill turtles feed on seagrass beds. Accessible by boat, it’s a world-class snorkeling spot where you can observe turtles in their natural habitat from just a few feet away. No certification needed, and perfect for non-diving companions.

When to Visit

Best Months for Diving

March through July offers the best combination of warm water (78 to 84°F), peak visibility (80 to 100+ ft), and calm seas. April is particularly special: coral spawning season begins, and PIMS runs its annual coral restoration expedition.

November through February brings cooler water (75 to 78°F) and occasional cold fronts that can reduce visibility, but there are fewer visitors and the marine life is still excellent.

Hurricane season runs June through November, with August and September carrying the highest risk. Travel insurance is always a good idea.

Where to Stay

Green Turtle Cay has a range of accommodation, from charming guesthouses to waterfront villas:

  • Bluff House Beach Resort & Marina: The island’s largest resort, with a hilltop pool, restaurant, and its own beach. Good base for divers with marina access.
  • Leeward Yacht Club: Boutique waterfront cottages with a full-service marina. Popular with boaters and divers alike.
  • Vacation rentals: Several private homes and cottages are available through VRBO and Airbnb. Best for groups or extended stays.
  • New Plymouth Inn: A historic guesthouse in the heart of the settlement, walking distance to restaurants and the ferry dock.

Island Culture and Things to Do

Green Turtle Cay isn’t only for diving. The main settlement of New Plymouth is one of the most charming communities in The Bahamas: pastel cottages with white picket fences, a population of about 550, and a genuine warmth that makes visitors feel like neighbors.

  • Miss Emily’s Blue Bee Bar: The legendary birthplace of the Goombay Smash. Essential.
  • Albert Lowe Museum: The oldest museum in The Bahamas, covering the island’s Loyalist heritage dating back to the American Revolution.
  • Sculpture Garden: An outdoor gallery by renowned local artist Alton Lowe.
  • Coco Bay Beach: A pristine crescent of white sand on the island’s Atlantic side. Often empty.
  • Sundowners: Watch the sunset from the deck with a rum punch. The name says it all.

Dive + Conservation: The PIMS Expedition

If you want more than recreational diving, the Green Turtle Cay Expedition run by the Perry Institute for Marine Science is the best way to experience the island. Over 7 nights, you’ll:

  • Dive the Coral Caverns, Catacombs, and USS Adirondack
  • Plant corals on degraded reef sites alongside PIMS marine scientists
  • Earn your PADI Reef Rescue Diver specialty certification
  • Snorkel with wild green and hawksbill turtles at the Turtle Lagoon
  • Join a small group of just 8 divers for an intimate, mentorship-driven experience

The 2026 expedition runs April 12 to 19. It sells out quickly, with only 8 spots available.
