Mountain Biking Safety

  • Stay in control at all times.  It is your responsibility to avoid other persons and objects around you.
  • Do not stop where you obstruct a trail or are not visible from above.
  • When entering a trail or staring downhill, you must look uphill and yield to other riders.
  • Please assist if you are involved in or witness a collision or accident and identify yourself to the Bike Patrol or Bike Trail crew.
  • Keep off closed areas and obey all signs and warnings.
  • Stay on marked trails.  Do not cut switchbacks.
  • Stay off lifts and out of the Bike Park if your ability is impaired through the use of drugs or alcohol.
  • You must have sufficient physical dexterity, ability and knowledge to safely ride and unload lifts.  If in doubt, ask the attendant.
  • Hiking in the Bike Park is not permitted.
  • Do not feed, provoke or approach wildlife.

The Mountain Biker's Responsibility Code has been developed to help inform riders about the information, decision-making and actions every rider should know and take prior to and while riding on the variety of trails within a ski area’s trail network.

Similar to the 10 points of Your Responsibility Code, this code reminds riders that there are elements of risk in mountain biking that common sense and personal awareness can help reduce. Check with area employees to see if there are other local considerations for which you should be aware, such as wildlife.
