This is the basic approach for all of the Plateau areas.
Drive to campground and leave your car either to the campground parking or drive a little further. If the further parking is full, fall back to campground parking, the space does not run out.
The walk-in is around 600m, and should take around 10 minutes. On the way to Poison Dwarf, the Human Energy is on your right side.
The walk to Far Plateau is another 200m, Arch Valley is around 300m.
You can also take a short cut from Arch Valley to Dihedral boulders. The short cut starts from the far end of Arch Valley and it's around 400 meters.
