Three Mile Canyon Park sits along the Columbia River near Boardman, Oregon, giving campers direct views of the water from dispersed sites. Rattlesnake warning signs are posted at the bathrooms, which are stocked with toilet paper. The park draws crowds, particularly on summer weekends, so noise from neighboring groups is a realistic possibility.
