Volunteer Trail Cleanup Event: Lemhi Mountains, ID

onX Offroad and Toyota are partnering with Idaho Parks & Rec and Salmon-Challis National Forest for a fun-filled weekend of building a new bridge in the backcountry of the Lemhi Mountains of Idaho. We’re calling for volunteers to help move building materials and assemble a bridge to mitigate impacts on the creek habitat while keeping trail access open. Sign up below to volunteer, and come ready to put in some work and help make a difference. 

Please Note:

  • This is a two-day volunteer trail work weekend. There is camping at Big Creek Campground at the trailhead, as well as plenty of other dry camping in the valley for Friday and Saturday nights. 
  • North Fork Big Creek is a multi-use trail—so dirtbikers, hikers, mountain bikers, and horseback riders are all welcome to participate.

🔥Win a Chainsaw! Not only will you feel good keeping trails clear, but one in every ten attendees will take home a brand-new chainsaw from each Trail Revival Project!
