Okay...I've written to some folks down there and asked around. It looks as if the only cave dive (if it really is a cave dive) known in the BVI is called Grand Central Station near Guana Island and it is described as a tunnel leading under the island itself with depths ranging from 55 to 75 feet. I don't see any mention of cave certification or extereme warnings of hazards, so I would tend to believe it's a cavern to us. I would have to see for myself and I don't have plans to be down there real soon.

I would like to thank "We Be Divin" (http://www.webedivinbvi.com) in Cane Garden Bay, Tortola, BVI for getting me on the right track to find this information. They have recently recieved permission from the government there to take small groups diving off of Anegada, if anyone is interested, and I work for The Catamaran Company, so I encourage anyone heading to the BVI to charter with us (http://www.catamarans.com).
