Free camping along the Tongue River draws RVs and tent campers to this Montana Fish, Wildlife & Parks site located 12 miles south of Miles City. The single-lane access road opens to a grassy clearing with roughly eight camping spots, though site boundaries remain informal. RVs up to 20 feet can navigate the entrance and find level ground.
Two vault toilets serve the area and stay well-maintained according to multiple visitors. Each designated site includes a picnic table and fire ring, with the closest spots to the dam offering direct water access for fishing and dog play. "No real shade, as you get closer to the river," notes CATHLEEN B., though some sites farther from the water provide more tree cover.
The location stays relatively quiet despite nearby farms and occasional highway noise. Cell service reaches 2-3 bars on AT&T networks. Campers report clean facilities and mowed grass throughout the season. Black flies can be heavy during summer months, particularly in July.
No water or trash services are provided, so visitors must pack out all waste. For additional camping options, travelers can find campgrounds near Miles City within 15 minutes of this fishing access site.
