Little Bighorn River mouth of the Little Bighorn canyon there is a gravel road maintained by Bighorn County. However, from the point at which the river flows out of the canyon (at about the Wyoming-Montana state line) the road continues upstream in the canyon for only about 2 miles. There are two (and sometimes three) unbridged stream fords. This portion of the road is unmaintained and is a two track road with tight turns. It is primitive, rough, ungraded, and littered with partially buried boulders. When it rains large puddles accumulate in low spots. It is impassible in the winter after snow accumulates
Little Bighorn River and after the two stream fords, fed by springs, partially freeze over. When not closed by winter weather, this road still requires vehicles with high clearance, preferably with 4X4 gearing. In Wyoming, and particularly in the Little Bighorn Canyon, all the land adjacent to the road and the stream is private, and a sign noting this is posted at the entrance to the canyon. At the furthest point of the road, two miles upstream from the canyon mouth, on the US Forest Service boundary there is a parking area maintained by the Wyoming Game and Fish Department but signage prohibits
