Mount Roraima is a spectacular tabletop mountain (tepui) located at the tripoint border of Venezuela, Brazil, and Guyana, with the largest portion lying in Venezuela’s Canaima National Park. Rising about 2,810 meters (9,219 feet) above sea level, its sheer cliffs and flat summit create a dramatic and otherworldly landscape often shrouded in mist. Mount Roraima is considered one of the oldest geological formations on Earth, dating back around two billion years, and it inspired Sir Arthur Conan Doyle’s novel The Lost World due to its unique biodiversity and remote, mystical appearance.
