Mountain Biking
Known for flowy, laomy buff singletrack complemented with more rowdy, advanced terrain in the sub-alpine and alpine, riders can turn it up for weeks on end without ever repeating the same ride. In a place where every ride takes you somewhere magical, it's as though you've arrived in mountain bike nirvana. As of summer 2014, Sun Valley Resort added lift-accessed mountain biking on Bald Mountain. With 3,400 feet of vertical drop to the valley floor, the European-style ski mountain lends itself quite well to a hair-on-fire big mountain experience on two wheels.
Be Trail Kind
No matter our differences in backgrounds or how we choose to enjoy the great outdoors, trails create common ground that connects us. Access to trails is a privilege we acknowledge and can only safeguard through our actions toward one another. Treating each other with kindness in how we share the trails and interact with each other is more important than it has ever been. Everyone deserves to pursue happiness in nature. Let’s rise together to ensure a positive trail experience for all.
Guided Experiences
The best way to get the most out of your time in Sun Valley is to link up with one of the many great guiding services in town. Guides not only know all the best trails but also how to avoid crowds and adapt a trip to the best of your abilities.

E-Biking in Sun Valley
E-bikes have created incredible opportunities for a wide range of users to get out on two wheels. From cruising the local bike paths to exploring the single track, these machines can take on a wide array of terrain.
We're fortunate to have some 200 miles of e-bike friendly trails to enjoy here in the Sun Valley, Idaho area.
Unfamiliar with e-bikes? An e-bike is any form of bicycle that has an electronic motor that allows for pedal assist, throttle, or any form of motorized assistance to the rider.
E-Mtbs Trail Access
E-Mtbs are only allowed on designated trails. They are considered their own user group and follow similar motor vehicle guidelines. They are allowed on ebike and motor vehicle labeled trails or where otherwise designated by the overseeing land management entity. You can hover over trail names on the BCRD Summer Trail Link to see whether a trail is e-mtb friendly or not.
It is the responsibility of the land management agency to provide signs with route numbers on all trails. It is up to YOU, the user, to know what trails are motorized or not.

Mountain Biking Trail Etiquette

- Stick to Open Trails | Abide all trail rules, regulations, and closures and only ride open trails. Don't trespass over private property or federal and state protected lands.
- Share the Trail & Yield | Be a courteous rider and yield appropriately to others. Bikers should yield to hikers, horses & uphill moving dirt bikers. Yield with one foot on the ground and two wheels on the trail. When yielding for horses, step to the downhill side of the trail. Downhill bikers yield to uphill riders. In many cases, hikers will yield to uphill bikers.
- Leave No Trace | Stay off of muddy trails don't cut corners, or skid your turns to help us maintain the integrity of the trails. We also ask that you pick-up any wrappers and trash that you might accumulate along the way.
- Stay in Control | Keep your riding in control and be sure that you can safely stop for others.
