Oxbow Creek Campground (Sand Creek Access Area) offers free camping along the Yellowstone River with multiple dispersed camping areas accessible via gravel road off I-90.

The site features vault toilets, scenic creek access with a nearby waterfall, and accommodates both RVs (up to 34 feet with careful maneuvering) and tent camping with a 5-night stay limit.

Note that the access road is washboard gravel and can be challenging for larger rigs; smaller vehicles and tent campers are better suited for the main East Oxbow area, while additional pull-offs downstream accommodate larger vehicles.
