This campground is perfectly situated next to, some sites are almost on the trail, the Tunnel Hill trail. The campground is clean and well maintained and all sites have electric. handy for charging up all your electronics at the end of the day. Water is also available. bathrooms are pit style and one negative would be lack of a shower house. Great place to stay if you are riding the entire Tunnel Hill trail.

Alto Pass is a pretty little town on the River to River Trail. It has great views and a little country store. Here (at the intersection of Chestnut & Main) you're in the perfect spot to hike northeast or west on the River to River Trail, or you can hike the Quetil Trail, just southeast of here, to a bluff overlook.

Panther Den Wilderness is a spectacular mix of forest and massive, building-sized chunks of rock with narrow walkways between them. You can primitive camp anywhere in the wilderness as long as you stay out of designated natural or research areas, which should be marked with yellow posts. The area around here can be especially convenient because of its proximity to the creek for water; keep an eye out for old fire rings so you won't have to build one.

Karnak is not the end of trail but it is the last point on the trail to camp. The Main Brothers camp ground is pretty simple but it is the only campground at the south end of the trail. The campground is clean and in the main campground there are spots for tents.
