Site Overview

Inside the Grand Anse Marine Protected Area — a no-fishing zone that guarantees the fish stay — the artificial reef structures sit on open sand doing the slow, optimistic work of becoming coral reef. The young colonisation is the story: encrusting sponges, branching transplants and the first generations of damsel and grunt staking out territory around the modules, with the whole sand plain humming with settlement. Structures top out near 8 m with the sand floor at 15-18 m — a short, deep-ish lap with very long no-deco times. The site sits in South Coast (Atlantic Side), one of Grenada's core dive areas, with water at 27-29 °C and typical visibility of 10-25 m. Directly off Grand Anse beach — the quickest boat ride of any site on this list. Not Grenada's most famous structure, but quite possibly its most forward-looking dive — repeat visits over a week show genuine, visible change on the modules. Trade winds blow almost constant over the Caribbean, and it is their lulls and builds that set the daily diving schedule around Grenada. Water temperature stays in the high twenties year-round and the island sits outside the main hurricane belt, so the dive boats run twelve months a year.

Dive Briefing

“Drop onto the nearest module cluster and transect the structures at your own pace; guides point out the colonisation markers and the transplanted coral heads along the way. Depth management: plan the dive to a maximum of 18 metres and turn early. The sheltered Caribbean side is usually glassy, while the Atlantic-facing south coast runs with the trade-wind current that makes its drift dives so special. Staged ascent above the structures with the safety stop taken looking at the colonisation, not a rope. Newer divers can comfortably dive this site, staying within the range flagged by the guide. Several of Grenada's best waters are protected - the Grand Anse Marine Protected Area, the south-coast preserves and Carriacou's Sandy Island/Oyster Bed MPA all use mooring buoys and small user fees to keep anchors off the coral. Local operators hold the final say on which sites run each day, because a shift in wind or swell can change conditions between two bays.”
