Cool, deep waters await you at Titou Gorge, in the rain forest that leads up to the famous Boiling Lake. If you're wearing water shoes and a flotation device, you can make your way upstream through a series of pools that ends at a waterfall. The gorge's smooth cliff walls were created by molten lava. If you've seen Pirates of the Caribbean: Dead Man's Chest, then you've seen Titou Gorge! Portions of this movie with Orlando Bloom were filmed in this very spot.
