Want to feel on top of the world where the craggy peaks meet the clouds? The 2-billion-year-old Mount Roraima is where you should be head. Made famous for inspiring Sir Arthur Conan Doyle’s novel, ‘The Lost World’, and more recently Disney’s Pixar film, Up, the mountain rises more than 9200 feet above the ground making it the tallest peak of the country. Roraima, a massive tepui (table-top mountain), lies on the Guyana Shield and its sandstone cliffs ride straight up from the lush rainforests all around. At the peak, the vegetation is scanty, yet the vast majority of species of fauna exist only on tepuis like Roraima. This magical landscape features surreal rock formations, the quartz crystals of Crystals Valley, and endemic orchids, carnivorous plants, and the intriguing Roraima bush toad. Mount Roraima is definitely a must-see destination in Guyana.
