Trail begins in a large grassy hillside, climbs steadily to a ridgetop, and ties into Kachess Ridge Trail 1315. This trail is the primary access to Thorp Mountain Lookout. Continue north on 1315 for 0.5 mile, then north on 1315.2 another 0.5 mile to the lookout. The lookout is sometimes staffed and provides an outstanding panorama. There is no water along this trail but there is a spring 0.25 mile north of trail 1315.2, along trail 1315.

The first notable mention should be to the roads; Forest Service Road 4308 (French Cabin Rd) is a typical forest service road with gravel and washboards and is fine but the last couple of miles on Road 120 up to Knox Creek could be hazardous to a passenger car. It is narrow, mostly due to brush, with many ruts and rocks. A high clearance vehicle would be recommended and some buffing may be in order on your paint job when you get home.

The first mile, with an 1100’ gain, started with a series of switchbacks across a brushy hillside fully exposed to the sun. The trail is very overgrown in sections. However, the short and quick access affords you stunning views as you crest the ridge!
