The largest lake of the world stretches over 2.000 m of altitude, and the highest navigable lake (3.808 m). It measures 194 km long by 65 km wide, it covers 8.710 sq. km (5.260 in Peru, 3.450 in Bolivia) and it's 281 m deep at the most; it's difficult to imagine that it takes almost a day to cross it in boat.
At this altitude, because of the pure air, the lake is especially clear (65 to 15 m); and for the exceptional light quality, mountains that seem very close are in fact at 20 or 30 km.
This lake offers an extraordinary fauna composed of ducks, fish like suche, capache and trout, as well as alpacas and llamas among others. The flora is composed, among others, of reed, that is used not only for food but also as a building material for houses, canoes, etc.
You can find Uros, living on floating islands on the lake, made of reed, which are the descendants of one of the oldest people of America.
The weather is dry and cool (20°C to 0°C), and the rainy season is from December to April (annual precipitation 728 mm).
