Shoup Bridge  Campground is a small Campground surrounding cottonwood trees along the banks of the Salmon River. It is also right along the Highway.  We found this a pleasant campground to stay in, plenty of flat ground for our tents and only $5 a night.  A few sites are quite small, but still room for a tent. This was our Scouts jumping off point for a backpacking trip the next day.  While next to the highway we expected a lot of noise during the night, but that was not our experience, the only real road noise we had was in the early morning with worked out as it helped wake us up.  Each site has a picnic table and metal fire ring.  Water is available and the area has a vault toilet and trash cans.  Campground has a boat launch.
