Mudslide Forces Indefinite Closure of Grandjean Campground and Trailhead

The Grandjean Campground and its associated trailhead, located approximately 7 miles down Grandjean Road/Forest Road 524 from Highway 21, are closed until further notice. This decision follows a significant mudslide that occurred earlier this week, leaving the site covered in heavy debris.

Authorities from the Sawtooth National Forest issued an alert confirming the indefinite closure, noting that the site remains inaccessible to the public while assessments continue. The Grandjean Trailhead is a key gateway for hikers exploring the Sawtooth Mountains; those with plans to traverse the area are urged to adjust their itineraries and avoid the vicinity for their own safety. Updates regarding the cleanup process and potential reopening dates will be provided by the Forest Service as they become available.
