Painted Rocks State Park

About

Painted Rocks State Park encompasses 23 acres along Painted Rocks Reservoir in the remote West Fork Valley of the Bitterroot Mountains, approximately 40 miles southwest of Hamilton. The campground features 25 sites set in a western pine forest, offering a mix of tent and small RV camping. Sites include established fire pits, grills, and picnic tables, with vault toilets available throughout. Campers must bring their own drinking water and pack out all trash. The reservoir provides excellent fishing opportunities for rainbow and brook trout, along with boating, swimming, and paddling. A boat launch and dock are available, though low water conditions may limit motorized boat access. The surrounding Bitterroot National Forest offers additional hiking and wildlife viewing opportunities. Six sites are reservable Thursday through Sunday from Memorial Day to Labor Day through Reserve America, while the remaining 19 sites operate first-come, first-served year-round. Most sites accommodate vehicles up to 25 feet, with two sites allowing up to 35 feet. The narrow access road and small camp spurs make this campground unsuitable for large RVs or trailers.
