Easy enough drive up to KM2.75. On this stretch there are small, yet aggressive waterbars approximately every 50m. I don't think these would cause much trouble in a AWD crossover type but would need to be taken slowly. The first 2 hairpin turns are very sharp however, each has a very large area to turn around or even park.

After KM2.75 I'd rate this road 4x4 HC. You'll definitely want something with a good low range as its very steep. I had no issues with traction whatsoever however, I was aired down and had a couple hundred pounds in my bed. The small switchbacks KM2.75-3 were fine driving up in 4x4 unlocked diff without having to do a 3 point for the turns.

After the steep switchbacks you go up and over the highpoint, then back down another steep section. From there is a pretty easy drive until just before the end where there's another steep hill. I didn't bother to drive up and parked at the bottom. Theres enough room to park at the top, but its still on a pretty good slope.
