From Park, go down the asphalt up to a bridge.
If it's busy, from the parking take a dirt road south-west, a spur to avoid the asphalt. The spur (unsigned) runs all the way up to the Noble Canyon Trail head.
Cross the bridge and go down towards the creek and more or less follow the creek.
At the Noble Canyon Trail Head Road, follow the asphalt to the Noble Canyon Trail Head.
A somewhat rocky trail heads uphill, watch out for mountain bikers.
Along the route there is plenty of shade.
As the Noble Canyon Trail, turns east keep on heading north-west up to the parking.
How to get here:
From the S1, exit on the gated unsigned Pine Creek rd at mile 28, and follow the asphalt, once below at a gate, turn left heading downhill.
The road is somewhat maintained, mostly a one lane asphalt road, with some gravel and deep potholes.
Some ground clearance is needed because of the potholes.
There are several spots to park and primitive campgrounds along the road.
Gates are sometimes unpredictable closed.
Now park at point "Park" (free).
From Old Hwy 80, turn on Pine Creek Rd, exit on the Noble Canyon Trail head.
No gates here, a good 2 lane asphalt road.
A large parking with a parking fee (Adventure pass).
