This road is great for its natural beauty You'll spot some of the local fauna, spread around the Andes pre range and range. This used to be the old pass to Chile. Make sure you take something for your nausea because there are 365 turns and you may get dizzy. The road leads to Uspallata and from there you can...
Their wildlife give you the opportunity to see a lot of Cóndores & Huemules in their own habitat.
Their 365 views are breath taking and the route (52) is totally well recommended during spring, summer and fall.
This drive up to the summit was amazing with a lot of wildlife and breath taking views this climb up to about 2880 passing over to the main Andes above the clouds!!! We done this in a 4+4 and would definitely recommend this as roads are un paved!
