Laguna Alcacocha is a high mountain lake at an elevation of 4.350m (14,271ft) above the sea level located at the top of the Andean mountains in the Pasco region of Peru.
The road to the lake is called 103. It’s gravel, narrow, and very muddy and slippery after rains. Avalanches, heavy snowfalls and landslides can occur anytime, being extremely dangerous due to frequent patches of ice. The climb is simply terrible, with a notorius lack of oxygen that tests the organisms and a high degree of steepness. Most people feel altitude sickness at around 2,500-2,800 meters.
