Southwest Idaho Mountain Bike Association


The following Idaho State Parks offer bike trails:

Idaho is blessed with over 14,000 miles of single track trails available to mountain bikers and at least twice that in 4-wheel dirt roads. Idaho is a jewel waiting to be discovered by mountain bikers. Many of the trails have not been ridden yet, partly due to their remote locations and difficult terrain. The primary providers of mountain bike trails in Idaho are the U.S. Forest Service, Bureau of Land Management, and Idaho Department of Parks and Recreation.

Trail Etiquette

  • Ride on Open Trails Only
    Respect trail and road closures (ask if not sure), avoid possible trespass on private land, and obtain permits and authorization as may be required. All wilderness areas are closed to cycling.

  • Leave No Trace
    Be sensitive to the dirt beneath you. Even on open trails, you should not ride under conditions where you leave evidence of your passing, such as on certain soils shortly after a rain. Observe the different types of soils and trail construction; practice low-impact cycling. This also means staying on the trail and not creating any new ones. Be sure to pack out at least as much as you pack in.

  • Control Your Bicycle
    Inattention for even a second can cause problems. Obey all speed laws.

  • Always Yield The Trail
    Make known your approach well in advance. A friendly greeting (or bell) is considerate and works well; don't startle others. Show your respect when passing others by slowing to a walk or even stopping. Anticipate that other trail users may be around corners or in blind spots.

  • Never Spook Animals
    All animals are startled by an unannounced approach, a sudden movement, or a loud noise. This can be dangerous for you, for others, and for the animals. Give animals extra room and time to adjust to you. In passing, use special care and follow the directions of horseback riders (as if uncertain). Running cattle and disturbing wild animals is a serious offense. Leave gates as you found them or as marked.

  • Plan Ahead
    Know your equipment, your ability, and the area in which you are riding an prepare according. Be self-sufficient at all times. Wear a helmet, keep your machine in good condition, and carry necessary supplies for changes in weather or other conditions. A well-executed trip is a satisfaction to you and not a burden or offense to others.
