Martha Brae's Rafters Village 

(Montego Bay; ): Martha Brae's Rafters Village offers the best river-rafting experience in and around this popular resort. You sit on a raised dais on bamboo logs and watch the river scenery unfold.

The Black River 

(South Coast): You can explore what feels like real Tarzan country, with mangrove trees and crocodiles in the wild, on an outing with South Coast Safaris . Lots of wild things grow in these swamps, and birders delight in the bird life. 

Green Grotto Caves

(Discovery Bay; ). These limestone caves were once used to hide runaway slaves. They're a world of stalagmites and stalactites, with seemingly endless chambers and eerie Grotto Lake, which you can visit in a boat.

Somerset Falls

(Port Antonio): Waters from the Daniels River race down a deep gorge through a rainforest. Flowering vines, waterfalls, and foaming cascades form a lush backdrop. You can swim in the deep rock pools.

Rafting on the Rio Grande

(Port Antonio; ): Shades of Errol Flynn, this is the grandest rafting experience in Jamaica. The rafts are propelled by bamboo poles.

Exploring the Blue Mountains

(outside Kingston; ): This is one of the biggest, wildest, and greenest parks in the Caribbean, ideal for exploring. You must hike 5 to 6 hours through thick vegetation (hearing amazing birdsong on the way) to reach the summit.
