Spread over 3 million ha in south-eastern Venezuela. Roughly 65% of the park is covered by table mountain (tepui) formations. The tepuis constitute a unique biogeological entity and are of great geological interest. The sheer cliffs and waterfalls, including the world's highest (1,000 m), form a spectacular landscape.
Canaima was established as a national park in 1962 and its size was doubled to the present area in 1975. The park is best known for the unique table mountain (tepui ) formations: there are numerous waterfalls, including Angel Falls with a free drop of 1,002 m. The high level of endemism found on the summits of the tepuis has led to the recognition of Pantepui as a unique biogeographic entity.
The park protects the headwaters of the Caroní River which supplies Guri, the country's largest hydroelectric power station and source of 60% of the nation's energy. The savannah portion of the park is inhabited by the indigenous Pemón people, many of whom are settled and dependent on three Capuchin missions. A main road from Ciudad Bolivar runs along the eastern border of the park, bisecting its south-east corner and providing easy access for tourists. There are no other metalled roads within the park, the western section being accessible only by air.
