Mount Roraima is a gaint. It 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. It is About 9 miles (14 km) long and 9,094 feet (2,772 metres) high.
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. It is the source of many rivers of Guyana, and of the Amazon and Orinoco river systems. Due to the altitude, nights on the summit are cool. You may find yourself having to ascend or descend the path up the cliff in heavy rain in which case there will be torrents of water rushing down the track and waterfalls in the upper areas that will hit you like a fire hose.
the mountain has long held significance to the indigenous people of the area and features prominently in their myths and folklore. It is the source of many rivers of Guyana, and of the Amazon and Orinoco river systems.
