One of Montana's newest state parks, designated in 2008, Yellowstone River SP's 200 acres leverage public access to almost 10,000 acres of adjacent wildlife management areas, offering prime hunting, hiking, and wildlife access, as well as 5 miles of eminently fishable Yellowstone River frontage.
Characterized by sandstone bluffs, canyons, and coulees, the acreage is currently undeveloped for camping, and a year-round fire restriction remains in effect at the time of writing.
Mourning doves, meadowlarks, mallards, Canada geese, wild turkeys, pheasants, sage grouse, sharptailed grouse, Hungarian partridge, mule deer, whitetail deer, pronghorn antelope, and an occasional elk frequent the landscape.
The road and parking are not recommended for RVs. The park is best suited, so far, for foot-traffic: hikers, hunters, fishermen, and snowshoers and Nordic skiers in season.
