West Boulder USFS Campground offers 10 sites along the West Boulder River with direct fishing access, picnic tables, fire rings, and vault toilets, though potable water is only available May 25 through September 1.

Located 16 miles south of Big Timber via US 298 and West Boulder Road, the campground accommodates trailers up to 20 feet and is open year-round, though winter access is limited by snow.

A $12 per night fee applies Memorial Day through Labor Day, and this is a pack-in/pack-out facility with a 16-day stay limit.
