The forest of undiscovered creatures
Aprada tepui, a remote rainforest mesa on the border of Venezuela and Guyana, is so little explored that in 2006 researchers discovered a cave - Cueva del Fantasma - large enough for a helicopter to fly into it. The area is also home to rare poison dart frogs, carnivorous plants and hundreds of other undiscovered species - and who knows, maybe a cave that can accommodate a jumbo jet.
Getting close:Orinoco Tours offers a 13-day hiking tour of Auyan Tepui, a similar mesa near the Rio Acanan, for around £1,000
