River Junction is a Montana Fish, Wildlife & Parks fishing access site located at the confluence of the North Fork and main Blackfoot River, offering 6 campsites with limited facilities (vault toilets only) and a carry-in boat launch for non-motorized watercraft.

The rough dirt road access and 7-day camping limit make it suitable for backcountry camping and fishing, though visitors should bring their own water and expect difficult road conditions, especially in wet weather.
