This is a delightful USFS campground along the North Fork of the Shoshone River just 3 miles outside of the East Entrance to Yellowstone with several of the sites on the river. There are no hookups and only HARD SIDE campers are permitted due to BEAR country. Each site has a fire ring & grill, picnic table and bear-proof food cabinet. The sites are all wooded with centrally located vault toilets and bear-proof dumpsters. Some of the sites can be reserved through www.recreation.gov, but many of them are "walk-up first come". A 14-day camping limit is imposed with your USPS Golden Age Pass entitling you to a 50% daily discount. It is about a 30-minute drive to Yellowstone's Fishing Bridge and commercial area! I have stayed there several times and it is our go-to-campground when visiting the park.

Threemile Campground is a well-kept, dry federal site about three miles from Yellowstone’s East Entrance along the North Fork Shoshone River. Wooded sites provide privacy and several sit right on the river; many are pull-through. It’s first-come, first-served with basic amenities only — vault toilets, a potable water pump, gravel roads, and no hookups or dump station; cell service may be unreliable. Camp hosts are described as helpful. Expect quiet evenings with occasional highway noise, nearby trail access, seasonal closure, and wildlife (including bears), so bring supplies and practice proper food storage.
