Lake Titicaca (Bolivia)
On the border of Bolivia and Peru is the highest navigable body of water in the world—Lake Titicaca. At an astonishing 12,500 feet above sea level, it is revered as sacred by ancient cultures as the birthplace of the sun. Here, indigenous culture continues to thrive in a unique water-based way of life. Isla del Sol is one of the highlights of the Bolivian side of the lake. Less than nine miles long, it is home to a Yumani village where the fountain of youth is rumored to exist, as well as many Inca sites like the ancient palace of Pilko Kaina and the labyrinth-like Chincana ruins. It is also here that the Roca Sagrada, said to be the birthplace of the first Incas, can be found.
