The trail does cross a small area of the Red Buttes Wilderness and there is a junction with the wilderness spur trail. The trail crosses from California into Oregon near Donomore Meadows. Pack and Saddle Stock Water can be scarce along the trail and feed is in short supply, so you may choose to camp near one of the adjacent lakes or meadows reached by spur trails. There is good feed and water in the Carter Meadows area though not in the established horse camps. Shelly Meadows can be lush and Marble Valley is a good break for grazing and water.
Paradise Lake has sufficient grass and camp sites east of the lake in the firs.
I found water at Reeves Ranch Spring which was one half mile from the trail, and at Alex Hole Camp one quarter mile from the trail, and Mud Springs two tenths of a mile from the trail. The camping is good at Mud Springs and Alex Hole Camp. It is a good idea to contact the local ranger district of the Klamath National Forest for up todate information on the area you will be traveling in.
