With over 400 miles of singletrack spread throughout the valley, the mountain biking is some of the best and most scenic in the country. Bald Mountain now boasts America's longest purpose-built downhill trail and over 3,100 vertical feet of thrilling lift-accessed trails. For a milder, family-friendly experience, head to the White Clouds trail network or meander through town along the leafy Wood River Trail, with over 30 paved miles to explore.



While you can hike or bike up Bald Mountain from multiple points, the only lift-served access is located at River Run Plaza (tickets available here and at the River Run Ticket Office). Please note, due to the Warm Springs Lift Project and forest health work from the Bald Mountain Stewardship Project, perimeter trails (Warm Springs & Cold Springs) are closed for 2023. From here you can load your bike on the state-of-the-art gondola, traveling 2,000 vertical feet in eight minutes.  You can load your bike on the Christmas quad chairlift all the way to the top, or take a few laps on the lower half of the mountain.
