Lake Titicaca, about 3810 m/12,500 ft above sea level), extends from southeastern Peru to western Bolivia. The lake is 196 km (122 mi) long with an average width of 56 km (35 mi).

Lake Titicaca is the remnant of an ancient inland sea and the blue waters make a beautiful contrast to the parched altiplano. Modern residents fish the lake using nets, much as their ancestors did.

Lake Titicaca is the center for archaeological and cultural studies as well as a favored tourist destination. If you go plan to visit in the summer months but take warm clothing. The days may be pleasantly sunny but the nights can be very cold. The lake is still sacred to the Aymara people who live there.
