York's Islands Fishing Access Site offers a concrete boat ramp and 10 well-spaced primitive campsites with picnic tables and fire rings along the Missouri River, located just off Highway 287 south of Townsend.

The site accommodates larger RVs (up to 52 feet reported), features a vault toilet, and provides direct river access for boating and fishing, though visitors should note there is no potable water and trash must be packed out.

Camping fees are $18 without a Montana fishing license or $12 with one; the rough dirt access road requires slow driving but is passable for most vehicles.
