Jamaica's water experiences are Caribbean and specific to an island shaped by the sea on every side. Blue Hole mineral spring river boat and waterfall experience near Ocho Rios — a natural freshwater swimming hole reached by bamboo raft and a cliff jump — are the most specifically Jamaican freshwater experience. Montego Bay sunset sailing and snorkelling catamaran cruises, Negril Seven Mile Beach glass-bottom boat tours above the reef, and Boston Bay to Portland Portland Bight Protected Area boat snorkelling tours add the coastal options. Rio Grande bamboo raft tours from Moore Town — a traditional journey on hand-lashed bamboo rafts down a mountain river, with the forest canopy closing over the water and the Blue Mountains above — and Port Antonio deep-sea fishing charters for blue marlin complete a water programme that carries the relaxed confidence of a country entirely comfortable in and on the sea.
