Mount Roraima is surrounded by three different countries (Venezuela, Brazil, and Guyana) whose borderlines intersect on the massive shelf, with all four sides being sheer 400-meter high cliffs. While its cliff walls are only scalable by the most experienced of climbers, there is a path up the mountain’s natural ramp-like path (usually a two-day hike).
However, the mountain is worth a visit for more reasons than its impressive cliffs. Mount Roraima, part of Venezuela’s 30000-square-kilometer Canaima National Park, is the site of the highest peak of the country of Guyana’s Highland Range. The mountains of this range, including Roraima, are considered to be some of the oldest geological formations known, some dating back to two billion years ago. Its near daily rains have also created a unique ecosystem which includes several endemic species, such as a unique carnivorous pitcher plant, and some of the highest waterfalls in the world.
