Agree with the below, stunningly wild.
Seriously windy, but we were fine two up on our g/s motorbike north to south and in a tent for the night.
Take your time on the route, some really rough/slippy/steep patches, normally all three at the same time!
I’ve included a couple of route photos, bit like the Bolivian alti Plano but without the horrendous washboard. About two dozen mad hairpins at the north of the route; steep corners with gentle route between them, many currently almost grassed over.
