Trekking the rainforest of Guyana (Times Online): "For Guyana’s lucky few visitors, the excursion into rainforest paradise usually begins on the Upper Essequibo River, at the Iwokrama reservation, just a few hours south of Georgetown."

But the author and crew had another destination in mind: the base of "Kaieteur Falls, among the most powerful in the world, located in the Guiana Shield mountain range, where precipitous sandstone peaks jut up out of the most extraordinary rainforest imaginable."

Enjoy the account of exploring untouched areas of Guyana's rain forest.
