Priest River Campground, Idaho This Corps. of Engineers campground is a very clean, well-maintained facility. This is one of the very rare occasions where we opted for a fee campground. In September 2001, the nightly fee was $14. The showers are extra: 25 cents for about 4 minutes. The campground hosts were a joy to visit with and we took many photos of spotted twin fawns that liked to romp on the hosts' lawn and eat their pansies!
