Canaima

Canaima is the central hub for tours and excursions to Angel Falls and the Kamarata Valley. The tourist camp was the idea of one of Jimmy Angel's best friends, Charlie Baughan, one of the region's most interesting historical characters. He chose his spot well.
The camp is situated on the shores of a beautiful palm-fringed lake with exquisite falls in the foreground, while tepuis tower in the distance.

Most people use Canaima as their starting point for Angel Falls, but there are numerous falls nearby, including the Salto Sapo, where you can walk behind the curtain, and Salto Yuri. Tour operators abound. At the last count there were at least ten.

A Pemon community lives near to the tourist camp and they sell arts and crafts. There are two overpriced shops in the area. There are now telephones and faxes, but no banks. Most tour operators will change money or cash travellers' cheques. It's best to come prepared.
