Places to camp along the way
There is a great camping spot where the trail crosses Chittam Creek, short of halfway to Sheep Creek but a good break after the climb from the pack bridge. There is also good camping at Johnson Saddle. The beach at Sheep Creek has some nice places both on the beach and across the bridge to camp but there are small patches of poison ivy here and there so watch for that. Along the Salmon River, there are good places to camp at beaches along the trail.
Note: Please contact the Slate Creek Ranger District, Nez Perce-Clearwater National Forest, if you plan to make this a pack trip with stock. As of late April, the trail from Wind River Pack Bridge to Johnson Saddle had four logs across it but the Forest has plans to clear it summer 2022. Otherwise, the trail is in great shape as the Forest maintains it every year.
Things to consider
The trail along the river is at a low elevation and can be very hot in the summer months. Plan accordingly! There have been reports in the late spring of numerous rattlesnakes along Sheep Creek and there are patches of poison ivy here and there along the Main Salmon River trail.
