Riding in the Lower Bay. You will need to walk out from the shore and then launch in knee deep water, riding over a couple of square miles of waist deep crystal clear water with white sand bottom.
Perhaps the finest beach in the world, definitely one of the quietest - it's normal to walk for miles and never see a soul. Sand is like talcum powder.
The island has a small airstrip and you can fly in from Beef Island (EIS) Airport on Tortola. Via Antigua from the UK or Puerto Rico from the US. Best way is to rent a boat as the BVI is the sailing capital of the world. Lots of expensive yachts but a few good deals to be found as well. The island is only 28 feet high but 14 miles long and 3 miles across. Just a big beach and reef in the middle of nowhere. Get to The Settlement and get somewhere on the water.
