Lago Titicaca

The highest navigable lake in the world, sitting at 3800m, is also the largest in South America. Lake Titicaca, once believed to be a sacred, inland sea by the Incans, is a marvel, straddling the border between Perú and Bolivia, South American countries with the highest per capita indigenous populations. It is not surprising that the ancient civilizations were in such reverence of the lake, with its sheer enormity, the sun rose and set along its horizon.

Argued to be the birthplace of the Incans, Sun Island sits on the lake, with many ruins alluding to its past. The lake is just another testament to Bolivia and Peru's geographical diversity, complete with desert, rainforest, mountains and the lake.
