The Cayes and the Belize Reef are a paradise for water sports enthusiasts, offering all the swimming, snorkeling, scuba diving, sailing, windsurfing and fishing anyone could ever wish for. If that's still not enough, travelers can canoe on the Macal, Mopan and Belize Rivers around San Ignacio and tube through caves along the Chiquibul River. The best hiking trails are in Mountain Pine Ridge Forest Reserve and the Cockscomb Basin Wildlife Sanctuary. Bird-watchers should check out the rivers, swamps and lagoons of the Crooked Tree Wildlife Sanctuary, midway between Belize City and Orange Walk, which attract flocks of migrating birds between November and May.
