River Trail (223) is an excellent hiking trail with a variety of views, habitat and topography. Parts of the trail follow the Clarkfork River, while other sections wander away from it. There is one stretch along a rock outcrop across a talis slope that should be crossed with caution. Although this is a designated mountain bike trail it should be noted that there are sections on both ends that are considered quite challenging. Not for beginners.
