Pettengill Campground is a small, rustic 3-site campground in the Beaverhead-Deerlodge National Forest located where the Wise River meets Pettengill Creek, offering direct access to fishing and nearby hiking trails along the Pioneer Mountains Scenic Byway.

Each site features a paved pad (suitable for RVs up to 24 feet), picnic table, and fire ring, with ADA-accessible vault toilets available; however, there is no potable water or garbage service, so campers must bring their own water and pack out all trash.

The campground operates mid-May through September at $15 per night and is located approximately 10 miles south of Wise River on Forest Service Road 73.
