Aquanauts Grenada Review – True Blue Bay, Grenada

Resort & Accommodation

Aquanauts Grenada is based at True Blue Bay Boutique Resort in St. George’s, about 15 minutes from the airport. The resort sits on a sheltered bay overlooking the marina and offers four pools, a gym, a restaurant, two bars, and a free beach shuttle to Grand Anse and BBC Beach. It’s a comfortable base for a dive trip.

The dive shop at Aquanauts also arranges dive‑and‑stay packages, which are worth considering if you’re starting fresh. I booked the resort separately through Expedia to use expiring travel points, but arranged the dive package directly with the shop — a quick and efficient process.

This trip was actually the second leg of a longer Eastern Caribbean swing. Before arriving in Grenada, I spent time on the island of Carriacou diving with Deefer Diving. Carriacou, a smaller island within the nation of Grenada, is just a short ferry ride away and pairs naturally into the same trip.

Dive Operation & Facilities

Aquanauts runs four purpose-built dive boats, which gives them a meaningful operational advantage: divers are grouped by experience level across boats, so advanced divers aren’t slowed down, and newer divers aren’t rushed. It’s a simple concept that not every shop executes well, and it makes a difference.

The daily schedule covers sunrise dives, two-tank morning dives, afternoon single-tank dives, and night dives. A selection of longer-range Atlantic wreck dives is also available on a more limited basis, carrying a small premium over the standard rate — and worth it.

Briefings happen right on the boat, where you’ll find dedicated camera tables and rinse tanks for your gear. Nitrox is available to certified divers, and since Aquanauts also caters to technical divers, they stock specialty gas blends for those deeper wreck penetrations. Entry is by giant stride; afterward, you can either climb the ladder back aboard with gear still on or hand it up to the crew first for easier reboarding.

Divemasters Frankie and Bruce led most of my dives. Both were knowledgeable, attentive, and good at reading the group. Marine life spotting was strong throughout the week.

Diving & Marine Life

Grenada has earned its nickname as the Shipwreck Capital of the Caribbean, with over 19 wrecks and 50+ dive sites spread across six reef systems and a handful of uninhabited islands. The variety really delivers.

I logged eight dives over the trip, including two-tank mornings, an afternoon dive, and a night dive. Two of the standout dives were the long-range Atlantic wrecks — the kind that take a little more planning and cost a bit extra, but absolutely justify it once you’re down there. These aren’t your typical Caribbean wreck dives. Grenada’s deeper wrecks feel like a different category altogether, and they were a major part of what made this trip so memorable for me.

Reef diving rounded things out nicely. It was classic Caribbean in the best sense — healthy coral, solid seagrass beds, and enough variety on each dive to keep things interesting. Over the course of the week I came across rays, nurse sharks, spiny lobsters, slipper lobsters, octopus, spotted and green moray eels, bearded fireworms, banded coral shrimp, whitespotted filefish, southern stingrays, French angelfish, porcupinefish, pufferfish, scrawled cowfish, and trumpetfish. But the night dive was probably the one that stayed with me most. Watching a roaming octopus work its way through the reef after dark felt like one of those simple but memorable encounters that ends up defining a trip.

The Underwater Sculpture Park, designed by Jason deCaires Taylor and the first of its kind in the world, is another notable draw. I’ve dived it on a previous visit to Grenada, though I couldn’t fit it into the schedule this time. Still, it remains one of the more unusual dive experiences in the Caribbean, and I’d recommend it if it’s your first trip to the island.

Grenada continues to stand out as one of the strongest all-around dive destinations in the Caribbean. The wreck diving alone gives it a clear edge for serious wreck divers, but the reef diving adds enough balance and variety to make the trip feel complete. Aquanauts made it easy to access both, and the operation felt organized, efficient, and comfortable throughout the week.
