Trails on the north side of the highway are multi-use and can be used year round by mushers. Trails on the south side of the highway by the visitors center can only be used late in the season once they're opened for multi-use.
Fish Creek, Lolo NF Highway 12
Another nicely maintained trail due to high snowmobile traffic. As far as we've experienced, an out and back trail.
East Fork, Lolo NF Highway 12
A few members of our group say they skijor here regularly. The teams have only run 3 miles up the trail. Good trail, beautiful, wide. Maintained by heavy snowmobile traffic.
