Very beautiful spot in the Andes, hidden from regular tourism, very authentic and preserved. The trip to there was a bit stressful (to me who has fear from heights), as the road does not look the safest and goes along the mountains growing in altitude with every meter. The camping place is also very nice, they rent sleeping bags and tents but bringing your own is better and cheaper, as the walk to the campsite is not even that much.
The altitude may be a problem, but a Sorochi pill resolves everything in an hour. Also at night could be extremely cold. Locals sell wood for campfire which is very convenient and important at night. Special equipment or at least 3 layers of warm clothes are a necessity there! Other than the inconveniences of the cold and the altitude, the hike is not the easiest but rewarding with some of the most beautiful views I've seen. Definitely worth visiting, I went twice :D
