Head on down
Hang up your sunhat and head underground to Harrison's Cave (001 246 417 3700; harrisonscave.com; B$40/£13), pictured, in the central highlands. This stream cave system – first documented in 1795 but not excavated until the 1970s – meanders for a mile through the coral limestone rock on which Barbados is built. Let a solar-powered tram speed you through tunnels and caverns, stopping for closer inspection of the pools, streams, cascades and waterfalls. Highlights include the Great Hall, a huge cave decorated with some quite spectacular stalactites and stalagmites, and the Rotunda Room, with its creamy-coloured formations.
