Lake Titicaca, Peru (between Bolivia and Peru)

At 12,725 feet above sea level, the world's highest navigable lake is actually quite cool indeed. Although the summer (January through March) sun can cause dreadful sunburn, the weather is still quite chilly and the water icy cold.

Subsistence farmers and herdsmen of llama and alpaca eke out a living in the shadow of nearby Puno's spectacular 18th-century stone cathedral. Catedral Basilica San Carlos Borromeo has an elaborate, baroque exterior and austere interior -- decorated with only a carved-marble altar plated in silver. Each February, more than 50,000 locals celebrate Fiesta de la Candelaria, which combines elements of the Catholic faith with those of Andean religions.
