This is a steep and wonderful trek. 6-7 hours of trekking uphill will bring you to the sacred lake Chillata. This lake is shrouded in legend and mystery, home to Inca ruins and witches can sometimes be seen at the shore communicating with the lake in a bid to heal people. A further climb to 5,038m brings you to the Glacier – striking and surrounded by small floating icebergs. Hummingbirds fill the silence with the fantastic views of Illampu and the stunning sunset completing this beautiful scene.
