Neat formations

Free camping in Custer Gallatin NF. No water, no trash collection. Many sites are really private with long driveways. Not all had tables and/or fire pits. Only a couple other campers there. Good views of The Castle which is part of Slim Buttes. Bathrooms needed some attention. Lots of flies. There is a map of campsites at entry off of SD20.

Quiet and private

This campground is amazing. The geological formations around us are beautiful, and this place is isolated. Granted, I am here on a weeknight, but there are only two other groups camping here. The campsites are spread out so you get tons of privacy.

Unique and beautiful

Yes, it is out of the way which makes it all the more desirable. This is a very private camping area with great access to vault bathroom facilities. Accessible It is an outcropping of rock, buttes and ponderosa forest with spectacular views of distant grazing land. It is quiet, remote and rustic. Bring your own water.

So peaceful

Such a quiet campground! There looks to be about 10 official spots? 6 with gravel back ins. There is 1 pull through spot. The official spots have a metal fire ring and picnic table. There are 4 vault toilets spaced out throughout the campground which is nice! They aren’t being cleaned at this time but still being stocked with TP. Extremely peaceful and not frequently used. During my 3 night stay, I had 1-2 campers I was sharing the campground with. There’s a nice picnic area at the entrance. There’s also an electric outlet up front if you need to charge something, with a donation box. I had 2 bars of LTE via ATT basically anywhere before the first camping loop. After that, 1 bar of 4G. Saw a forest ranger drive through one day. I’d definitely stay again and it’s free!

Nice Forest Service Campgroumd

Small campground most sites are private the vault toilets were very clean and the campground was quiet. Easy access and not far from Buffalo SD for gas and or other supplies. Very pretty scenery. We used it as a stop over on the way to the black hills and will do so for future trips

Quiet and beautiful

We stayed Wednesday and Thursday nights before the 4th of July. It's a beautiful, well kept no fee campground. A not difficult path leads you upward to a beautiful view of The Castles formation in the Slim Buttes. We will stay here again.

Solitude with a view

Great little campground nestled in the pines of the Slim Buttes. Views of more buttes and the prairie to the west with certain spots. Area is gorgeous in one of the most remote areas of SD. Can drive to campging spots a fair distance in to be away from the highway, although the traffic is almost nonexistant.

Some trails to the north of Highway 20 and on the south end of Highway 79 that can take you above and along the cliffs of the buttes with some more spectacular views. You can do some back-country camping if you camp within a certain distance of the trails (grab a forest service map at the campground for reference of trails/roads and private property).

Camping spots in the campground are clean, mowed and have a small fire pit.

Quite spot, lots of room

Really liked this free spot a few miles east of the main hwy. Great if you are traveling to the Badlands from the north. Lots of spacious sites here with established fire pits and several toilets. Coyotes serenaded us throughout the night!
