Definitly ride from East (US395) to West (SR49).
The climb to Sonora pass is unbelieveable...twisties like you wouldn't believe, but be careful, there are no warning signs and the road is hard to read.

Stunning highway wonderfully maintained by CalTrans.
This is an incredible daytrip from the Valley.
As soon as you get east of Oakdale, the terrain gets interesting.
108 is full of sweepers and hairpin turns.
The road is smooth asphalt and generally clean.
As you climb in elevation, the temperature drops and the views are unbelievable.
It's a really great ride leaving the valley and climbing quickly into the Sierras, just to see the diversity of California.
Be sure to go during the summer months as the pass is closed most of the winter and mountain weather can change quickly.

SR 108 takes a wide and slow path up from Highway 49 on the west slope, but as you get further up the mountain the road really narrows up and gets REALLY twisty!!
(Spend to much time taking in the breath taking scenery you will be road kill.)
The road surface stays good, being black asphalt most of the time.
Be sure to watch out for sandy/dirty corners from cagers clipping the shoulders!!
I suggest stopping often when safe to do so and take in this AWESOME pass over the Sierra Nevada range.
IMHO, SR108 is one of the most spectacular rides one can make in the central Sierra range, a MUST DO if you get the chance.
