Salt Island is one of the islands of the archipelago of the British Virgin Islands located about 4.7 miles south east (151 degrees true) of Road Town, the main town on Tortola. It is named after its salt ponds, which were once an important resource. The wreck of the Rhone is one of the best scuba diving sites in the Caribbean. Some of the underwater scenes in film The Deep were filmed in and around the wreck. The island is often visited by yachts and gets an occasional smaller cruise ship. Where before there were twenty or more households there are now only three or four derelict houses.
