The largest hotel on Jost Van Dyke [1] has six rooms, and most accommodations are in individual villas. There are a few no-frills apartment-style rooms and an excellent campground. Most visitors to the island sleep aboard sailboats. Land-based accommodation is found exclusively in Great Harbour [2] or White Bay [3], although some villas are under construction along the ridge.
