Lake Titicaca, which straddles the border with Peru, evokes images of Greek islands and Norwegian fjords. In 1872, a steamer was hauled to the lake piece by piece and reassembled on its shores. When the ship was put in the water, Titicaca became the highest navigable body of water in the world—a title it holds to this day. Lake Titicaca is the birthplace of two of the largest Andean cultures, the Tiwanaku and the Inca. You can learn about these vast and powerful empires as you trek along the shore of the lake or visit the Islands of the Sun and the Moon. At 3810 meters, the lake is surrounded by the snowy peaks of the Cordillera range of the Andes Mountains—many of them exceed 6000 meters. The lake seems like a huge blue oasis in the vast desert of the Bolivian altiplano.
