13 World Wonders You Can Still Visit Without the Crowds

13. Mount Roraima (Venezuela/Brazil/Guyana): The Lost World's Tabletop Mountain

Rising dramatically from the clouds at the border of Venezuela, Brazil, and Guyana, Mount Roraima is a colossal tabletop mountain, inspiring Arthur Conan Doyle's "The Lost World." This ancient tepui is a geological marvel, its sheer, 1,300-foot cliffs guarding a unique ecosystem of bizarre, endemic plants and animals found nowhere else on Earth. Its summit is a surreal landscape of alien rock formations, hidden pools, and constant mist. Reaching Roraima requires an arduous trek, preserving its untouched, mystical allure as a true natural enigma and a final frontier of exploration.
