Lake Titicaca

Lake Titicaca is the world's highest navigable lake at 3,812 metres, offering a unique cultural immersion on 42 floating reed islands built by the Uros people since the 15th century. These islands, constructed from totora reeds that require monthly replenishment, support a community of about 1,200 Uros who sleep on reed mattresses and cook on reed stoves. A boat tour from Puno costs roughly $15 per person, which is 70% cheaper than a typical day trip to the Nazca Lines. The lake's depth reaches 281 metres, making it larger than any high-altitude water body in the Andes.
