About Puno

On the western shore of Lake Titicaca, Puno is a base for the floating Uros islands and for Taquile, where weavers work in traditional patterns. The lake is the highest navigable in the world, and boats leave its harbour through the day. Inland, the funeral towers at Sillustani stand above a lagoon, with the lake road running towards Bolivia. May to September brings clear skies and cold nights; December to March is milder but cloudier.
