The Wolftone-Curran trail is part of a larger loop and is best runed in the direction shown. Climb a dirt road to the start of the trail which will be an ATV track. The ATV track will take you over the ridge and across to a pass where the true singletrack starts.
From the pass, you'll drop a little ways before continuing to traverse across the ridgeline. From the ridgeline, there will be a couple ups and downs before the final big downhill.
When you start to hit the switchbacks you are into the downhill proper. The switchbacks will drop you out to the creek. Once in the creek you'll descend with a couple short up and downs, as the trail winds on. In the end, you'll have a cold creek crossing across Deer Creek to finish out the loop along Deer Creek.
