Travel with Turpial Travel to one of the largest national parks in the world and the second largest in Venezuela. Canaima National Park astonishes visitors with the drama of its spectacular landscapes and biological diversity. Its signature landmarks are the tepuis, unique rock formations that rise up out of the surroundings to create huge ecological islands (the most famous, Roraima, inspired Conan Doyle's novel, The Lost World) punctured by waterfalls, including Angel Falls, the planet’s highest. In 1994, UNESCO declared Canaima National Park a World Heritage Site. The organization calls the park a "unique biogeological entity". It is best to visit Canaima National Park and the famous Angel Falls during the rainy season (from May to November) as dry season the rivers can run almost completely dry.
