Sun Valley Company reports updated Bald Mountain Trail closures:
Construction crews are ramping up work across the mountain to finalize the lift projects and get ready for winter. Starting Monday, September 14, most biking and hiking trails will be closed so crews can work safely.

Closed Starting September 14:
- River Run bike trails, up and down: Pale Rider, River Run, and Mindbender
- Hiking up those same trails, and up the middle of River Run to Olympic Lane/42nd Street to the Traverse trail
- Warm Springs Trail: Closed due to snowmaking upgrades and World Cup finish area work.
- Bald Mountain Trail (BMT): No estimated opening at this time

With BMT closed, hiking and biking access to the top is currently limited to Cold Springs only (out and back). Warm Springs is not an option for coming down from the top while this closure is in place.

Please respect all posted closures

Wildlife closures have been lifted on Cold Springs and Warm Springs trails.

All trails on Bald Mountain are non-motorized, and electric mountain bikes (e-bikes) are not allowed. Additionally, mountain service roads not designated as part of the trail system are closed to bike traffic.

Hiking: Hikers have numerous options on Baldy, with Trail #201 being the most direct and popular route. Beginning at the River Run Base Area, it follows the Big Wood River before climbing steadily through shady forest. The trail eventually opens up to grassy, sunlit slopes filled with wildflowers near the Frenchman’s lift area.

Many hikers take advantage of service road crossings for shorter loop options. Reaching the summit involves a strenuous climb of over 3,000 vertical feet, but it's a rewarding challenge for many outdoor enthusiasts.

Mountain Biking: Bald Mountain offers an expanding network of trails for mountain bikers. The Sun Valley Company has been actively developing and improving the system

With these and other trails, Bald Mountain now provides a wide variety of options for riders of all levels. Thank you to Sun Valley Company and its dedicated trail crew for these outstanding improvements.

Lift Access: During summer, the Sun Valley Resort operates the Roundhouse Gondola and Christmas Chairlift to the summit. This offers easy access for downhill mountain biking, dining at the Roundhouse Restaurant, and sightseeing and enjoying panoramic views.

For detailed maps, trail descriptions, and information on the history, geology, and wildflowers of the Wood River Valley, pick up a copy of Exploring Sun Valley online or at local shops.

Please check Sun Valley Company's website or the Sun Valley Company app for trail updates and information.

The City of Ketchum is building the Warm Springs Connector, a new trail from the Warm Springs Preserve to River Run on the west side of the river. During construction, the Bald Mountain Trail from River Run to the Traverse Trail and the French Connection cat-track will remain closed until sometime this fall.
