Traditionally regarded as the highest navigable body of water in the world (though there are higher lakes in Chile and Peru), Lake Titicaca is immense: its dimensions measure 233km (145mi) from northwest to southeast and 97km (60mi) from northeast to southwest, and it features an indented shoreline, 36 islands and exceptionally clear sapphire-blue water.
Titicaca is revered by the Indians who live on its shores; the Islas del Sol and de la Luna, two islands in the lake, are legendary sites in Incan creation myths.
The main town in the area is Copacabana, which has a sparkling white Moorish-style cathedral and is host to the Fiesta de la Virgen de Candelaria. Isla Suriqui is world-renowned for its totora reed boats, Isla Kalahuta for its stone tombs and Isla Incas is reputed in legend to have an underground network of passageways linking it to the old Inca capital of Cuzco in Peru.
