We camped here in a tent for a week and used it as home base to fish, visit Yellowstone and other nearby attractions. It’s inexpensive $12 a night with a Montana Fishing License or $18 without as a nonresident.
It is located on the Yellowstone River which was nice. Starting in the morning there is quite a bit of traffic using the boat launch.
There is a long gravel road that leads you to the boat launch and the campground. It is very dusty. They added more gravel one morning and our tent, even though completely closed up was covered in dust on the inside.
There is one vault toilet. There are no water spigots, showers, or trash cans. You must pack in and out all your trash. Food must be stored in bear proof containers or your car.
There is minimal shade and pretty much an open field other than a few camp spots on the river. It is also very windy most days and nights. You need a durable, well structured tent or it will collapse. Easy Ups aren’t a great idea unless you take them down if you leave for the day or when the wind picks up.
