Any Guyana adventure should include a visit to Kaieteur Falls, a one-hour flight from the capital city of Georgetown. At 741 feet, this spectacular falls is one of the largest single-drop waterfalls in the world – and flying above its edge in a 5-seater plane is a dizzying, jaw-dropping experience. During the wet season, the water thunders down with amazing volume and power, while the smaller flow during the dry season means visitors can walk right up to the edge (no guard rail here). Along with this natural wonder, Kaieteur National Park contains rare species like the Guianan cock-of-the-rock and the tiny, brilliantly colored golden dart-poison frog. Yet the area is still largely undiscovered. As the only visitors, we had the falls to ourselves.
