Painted Rocks State Park is a 23-acre park at 4,724 feet in a remote pine-forest setting in the Bitterroot Mountains, offering boating, camping, and fishing. It is named for the green, yellow, and orange lichens on the canyon rock walls. Painted Rocks Dam was built in 1939 for irrigation and water management, and the area is the historic homeland of the Salish. The campground has 25 campsites, six of them reservable May through September, and can accommodate RVs up to 35 feet. There is no potable water, but vault toilets, a dock, and a boat ramp are available. Visitors can fish, boat, swim, canoe, hike, bird watch, and photograph. Wildlife includes elk, mule deer, black bear, moose, and reintroduced bighorn sheep and peregrine falcons.
