Threemile Campground

 This USFS campground is very close to the eastern entrance of Yellowstone, and maybe that’s why it had such a busy, chaotic vibe. We drove through it on a Friday afternoon in  and all the sites were taken. To tell the truth, I’m not sure if we would have stayed there even if a spot was available. The sites were dusty and open with little privacy. 

Gendered handicap accessible vault toilets, dumpsters, host on site.

$15/night. Reservations can be made here, apparently, as there were several empty sites marked with a “reserved” sign. Each site has a bear box, fire pit, and picnic table. No tent camping allowed here due to bear activity. Hard sided campers only. Keep your food and anything that smells like food inside!! 

Closes in the fall for the season. 16 day stay limit. No cell service.

Potable water, trash, pit toilets, bear box, fire ring, picnic table

There are some great river sites.  A beautiful rail fence goes along the campground boundary.  Nice level sites and long enough for mid size RV's.  The backdrop of the mountains are wonderful.  I see no reason to travel into Yellowstone to camp.  Enjoy less crowded spaces and enjoy the Shoshone River as it bounces along side the rocky shore.

Threemile Campground is a nice campground just three miles from Yellowstone NP.  However this campground is not for tent campers as only hard sided campers are allow due to bears in the area.  The campground has 21 sites, all with picnic tables, metal fire rings and poles to hang your lantern on and bear lockers for food storage.  Vault toilets serve the campground.  Water is available as well as a bear proof dumpster for your trash.  And about those bears, two black bear cubs were seen just a few miles down the highway.   Campsite are nicely spread apart and sit in a mature pine forest.

We were able to drive in and choose a spot (September 9) but I can imagine during the summer peak times, it's probably fully reserved in advance. The location is great and a bear box is on site. The sites are a bit close together, and the bathrooms are clean.

After touring this campground, it had not yet opened for the season, we pulled back onto the road, and there was a GRIZZLY. There is a reason this, and other, campgrounds are hard sided only.

I can't wait to come back to this one though. So close to Yellowstone. The drive from this direction into the park is spectacular!

The campground is right on the Shoshone River. There is a water spicket that requires you to pump (old school method) to get drinking water. With no other services, make sure to being everything you need. There is a handicap vault toilet.

The sites are generous and private. The views are amazing. Check out the photos and vids.

Enjoy this true back to nature spot. You won't regret it.

Great spot close to Yellowstone. Was able to pull up and get a spot. The campground fills up on weekends but weekday arrivals it’s easy to just pull up. This is hard side only camping no tents due to bears.

I was one of the lucky scouts that went to buffalo bill during the philmont forest fire and it was one of the best experiences 2nd to none from philmont I highly recommend going if ur looking for somthing that will give u a challenge

This campground is popular with locals as well as travelers because of the beautiful scenery and wildlife viewing opportunities. It provides the chance unplug and truly relax, as there is no cell phone reception. There are 15 large sites; those along the west loop are a little farther from the road and quieter, and many sites offer a nearby view of the Shoshone River Bear spray is a necessity if you plan to fish the river or do any hiking in the area. It's always worth taking a drive into Yellowstone at both dusk and dawn for maximum wildlife spotting.
