Our family stayed in camp site number 3. We were pleased! It was not close to other campers. Shade all day in different spots, and large enough for our big tent. The bathrooms were clean for vault toilets. Well water worked just fine, and a quick walk to the river to splash around.

Pretty nice. Takes a hot minute to pump your water from the well but otherwise a fantastic campground. Fishing was good but the fish were small.

Facility was clean and peaceful, however the restrooms on Sunday were out of Toilet Paper And the biggest thing was the water had to much Chlorine to be used for drinking. There needs to be a warning on the reservation website about this. Many people use this water source while camping in the area as well as in Blackrock.

Blackrock is a great campground with easy access to the river. It is 20 mi down FS 327, which is not paved. But we took it with our travel trailer and did not have an issue. The entrance seems steep and narrow, but it is manageable.
The sites are pretty well spread out. For RVs, I would recommend not staying in the first 3 sites as they are small and have lots of obstacles.
