The Guffy Trail is easier to find going down from Guffy Camp. If you want to find it from Lark, go up Lark past the last curve, where it gets really steep. On the left, there's a gate & a (sometimes vague) road between houses. (The trail is not maintained.) Go around the gate & up the road. If you stay about on the top of the ridge, you meet up with the trail (which was fixed up by the U.S. Fosrest Srevice after one of the recent fires).
* NOTE * I haven't been on it in a year or so, so the access may have changed.
The trail goes up along the west side of one of the slides to Guffy Camp. In some places, you get a LITTLE too close to the edge of the slide and the trail is undermined. Avoid these spots, or name me as a beneficiary.
Just below Guffy, there's a small cinder block building on the west side that houses a spring. Quail are ususally abundant in the area.
Please let the rest of us know if the landscape has changed. Happy hiking!
