Alien-Looking Landscapes You Can Actually Visit on Earth

21. Mount Roraima, Venezuela – A Lost World Above the Clouds

Towering above the rainforest at the borders of Venezuela, Brazil, and Guyana, Mount Roraima is a breathtaking plateau that looks like it belongs in a fantasy novel rather than on Earth. This flat-topped "table mountain" is often surrounded by mist, giving the illusion that it floats above the clouds. Its towering cliffs rise nearly 1,300 feet (400 meters) straight up, creating an impenetrable fortress-like appearance. The landscape atop the plateau is equally mesmerizing—bizarre rock formations, crystal-clear pools, and carnivorous plants that seem to belong to a prehistoric world. Thought to be one of the oldest geological formations on Earth, this mystical destination even inspired Sir Arthur Conan Doyle's novel The Lost World. Trekking to the summit feels like stepping onto an untouched alien land hidden from time.
