Imnaha River Trail

This information provided USDA Forest Service

This trail (from access #1) is one that offers early spring access.There are many wildflowers along the trail in the spring. This trail is popular for its prime fishing, hiking and horseback recreational opportunities. The lower Imnaha River is dramatic with its steep, jagged canyon and white water. Remnants of an old mining town from the late 1800s and early 1900s are still visible at Eureka Bar/Mountain Chief complex, near the mouth of the Imnaha River. There are a few dispersed campsites at Eureka Creek. This trail also offers excellent wildlife viewings; you may even catch a glimpse of some of the bighorn sheep that reside in the area.


The trail is well maintained with no major stream crossings. Limited parking is available. The trailhead is on private land so please be respectful of the land and it’s owner. The trail is open to two-wheeled vehicles and mountain bikes but only to the confluence of the Snake River and Imnaha River. There are certain sections of the trail which are difficult to pack stock. There is an abundance of poison ivy along the trail and be on the lookout for the Western Rattlesnake, which is common to the Hells Canyon Country.
