Altiplano & Lake Titicaca
The highest navigable lake in the world, Lake Titicaca is a massive body of water with borders in both Peru and Bolivia. The elevation is 3,812 m (12,507 ft), which is high enough to leave you with a headache if you’re not yet acclimated to the altitude.
Culturally, it’s home of the Tiawanaku culture and according to some legends, the birthplace of the Incan culture. The name should probably be spelled Titiqaqa and it means “stone puma” in Aymara. You’ll see puma heads painted and sculpted onto just about everything.
There are two islands where most travelers go for a homestay: Amantaní and Taquile. They are small enough that they don’t have hotels or cars but large enough to have plenty of families to host as many travelers as arrive. There are also the famous Uros floating islands, which are smaller though they also have a homestay system.
