Go on a six-mile (10 km) cruise down the Rio Grande, the longest river in Jamaica. Sail on a bamboo raft for two poled by an expert raftsman who can share information on the flora and fauna of the region.  Originally used to transport bananas from the interior of Portland to the coast for export, the bamboo rafts began to be used in the 1940s for pleasure after Port Antonio's most notorious resident, movie idol Errol Flynn, arrived and started organizing raft races. The Earl of Mansfield later built the landing site, shops, and restaurant at Rafters Rest. Fuel your adventurous side on this 2-3 hour rafting cruise.
