Little Weiser River

The Little Weiser River winds through the rolling foothills and forested slopes of western Idaho in Adams and Washington Counties, descending from higher elevations in the mountainous terrain east of Cambridge before joining the Weiser River just southwest of the town. Its course passes through a mix of open ranchlands, riparian corridors, and wooded stretches typical of the region’s transition from the West Mountains toward the broader Snake River Plain. Anglers seek rainbow trout and cutthroat trout along its clearer upper reaches, while the nearby Little Weiser River Trail invites hikers, mountain bikers, and horseback riders to explore moderate paths with seasonal water crossings and quiet forest scenery, offering a peaceful outdoor escape amid the quiet rural landscape.
