Arc du Vero - Carriacou & Petite Martinique, Grenada
Site Overview
Arc du Vero is a shallow labyrinth of coral-arched swim-throughs — the kind of site that turns certified divers into children, because every passage opens onto another coloured room. The arches themselves are the star, draped in tube sponges and coloured growth, with octopus in the crevices, snake eels threading the sand moats, and every window framing a different fish scene. Everything happens between 6 and 12 m — a long, deep-breathing, low-air-consumption playground. The site sits in Carriacou & Petite Martinique, one of Grenada's core dive areas, with water at 27-29 °C and typical visibility of 20-30 m. A short boat ride directly from West Side along Carriacou's sheltered leeward coast, inside the MPA boundary — the water here stays diveable even on breezy days. Some sites impress; Arc du Vero just delights — the anchor scene here, full of tank-drifting photographers and arch-looping kids, is Carriacou at its happiest. 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
“Enter over the sand moat, then work the arch sequence at will; the guide takes the group through the main arcs one at a time so nobody surfaces from the wrong hole. Depth management: plan the dive to a maximum of 12 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. Ascend through any of the open columns — the whole site is safety-stop depth. 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.”

Traveler Notes
Who is this for?
The most fun a mixed group can have on one anchor: beginners thread the shallower arches, photographers stay married to the site for a whole tank. The 6-12 m range suits divers of most certification levels. It is also one of the island's best teaching sites for buoyancy and overhead-avoidance awareness. The crevices, wreck rooms and sculpture plinths hold the usual Caribbean small life - damsels, blennies, shrimps and the occasional rare frogfish or black seahorse. Night dives on the shallow reefs and harbour wrecks turn up a completely different community of hunters.
For Non-Divers
West Side is easy to enjoy without a cylinder, and most operators run snorkel trips on the same bays. 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.
