A shallow shore-diving site right at the southern edge of George Town, where two limestone outcrops (Eden Rock and Devil's Grotto) rise from a sandy 40-foot bottom riddled with swim-through tunnels, caves, and silver schools of resident tarpon. The dive entry is from a small ladder at Eden Rock Dive Centre.
Snorkellers can do the shallower swim-throughs in 10 feet of water; certified divers can go through the deeper caves on a single tank. The tarpon are unbothered by visitors and will let you swim through their schools — one of the better in-town dive experiences in the Caribbean.
