The surrounding area of Painted Rocks State Park was once the original homeland of the Salish Indian Tribe. The Salish tribe revered the area for its plentiful food that includes numerous berries, fish, and animals to hunt.

RV Rentals in Painted Rocks State Park



Painted Rocks State Park will be one of the more challenging state parks that you will have to drive to during your time RVing within the United States. There are quite a few different ways to get to Painted Rocks State Park from Montana State Route, with the most popular being by taking the West Fork Road. Traveling south from Darby is a challenging drive through rugged mountains and narrow roads. Along this drive, you will encounter plenty of hairpin turns and numerous curves that follow the banks of the river. If your rig is on the larger side and you are traveling at a slow speed, you should use turnouts when possible to allow for steady traffic flow. Once you arrive at Painted Rocks Reservoir, just north of the park entrance, you will encounter two hairpin turns that are also challenging to navigate.
The area is quite remote, and there are no major towns or cities within a close drive, so you must come prepared for this trip. You will need to haul in all of your water since there is no potable water available at the park, so it is best to get your supplies when you are closer to a town. Darby is the closest town to the park at around 24 miles to the north and the perfect place to get supplies.
When you arrive in the park, you will find more comfortable driving conditions. There is one somewhat narrow road, and caution should be used while driving on this road. You may find congestion in the park around the boat ramp and campground area if you are visiting during the weekends in the summertime, but besides these times, the park is not usually too busy. There will be plenty of parking if you just plan to visit for the day, but most travelers will opt to stay the night since this park is quite remote.
