Fat biking is a fun way to explore our winter trails at the Cross Country Ski Center. We welcome fat biking on designated trails when conditions allow. A daily fat bike ticket or fat bike season pass is required to access the trail system.

Always check the grooming report to find out if fat biking is permitted each day.

What Is Fat Biking?

Fat bikes are just like a regular mountain bike with extra fat tires, designed to travel on snow or sand. We offer machine-groomed and snowmobile-packed trails for fat biking and offer fat bikes for rent (subject to conditions and availability). We recommend wearing a helmet and appropriate winter gear at all times while riding a fat bike.

Fat Bike Tickets and Season Passes

  • A daily fat bike ticket or fat bike season pass is required to ride the trails at the Cross Country Ski Center.
  • Fat bike day tickets and season passes are sold separately from ski tickets and season passes. Additional purchase is needed if a fat bike pass holder wishes to ski or snowshoe. Ski season pass holders can ride at no extra cost if they rent a bike from us, otherwise an additional pass purchase is required.
  • Season passes can be pre-purchased online at Shop TD or at Alder Creek Adventure Center during the season. Pass holders are required to scan their passes at Alder Creek Adventure Center when accessing the trail system.
  • Fat bike season pass holders are welcome to ride as early as 7AM, when conditions permit. Day tickets are available from 8:30AM when conditions permit. Trails close at 5PM.

Fat Bike Rentals

We have a limited number of fat bikes available to rent on a first-come basis.  See rental rates here.  A fat bike trail pass is also required.

Please be sure to check the daily grooming report before leaving home and check with staff on arrival to confirm fat bike riding is permitted that day, and be prepared to ski or snowshoe if all bikes are out, or if it’s too warm or soft for a positive biking experience. Rentals are available on a first-come basis and cannot be reserved.

Trails Open or Closed for Fat Biking?

The snowpack has to be firm for fat biking. Riding when conditions are too soft is no fun and damages the ski surface. The grooming report will indicate if fat biking is allowed for the day and on which trails. Be sure to check the daily grooming report before leaving home, and check with staff on arrival as conditions change.

As a general rule, fat biking will not be permitted when:

  • There is more than six inches of fresh snow
  • The air temperature is forecast to be above freezing
  • Conditions are soft or wet

Rules and Etiquette for Fat Biking

  • Riders must confirm trails are open for riding and respect non-riding days/times as specified on the daily grooming report and communicated by staff.
  • Riders must purchase a fat bike day pass or season pass to ride within the Cross Country Ski Center boundaries.
  • Riders must remain on designated fat bike trails. 
  • Only purpose-built fat bikes are permitted! Bike tires must be wider than four inches and have pressure less than 10 psi.
  • Riders may not ride if tires leave a rut deeper than one inch. 
    • If you are leaving a trough deeper than an inch or are having a hard time riding in a straight line, it is too soft to be on the trails.
    • If you have to get off and push your bike, the snow is too soft and you should not be on the trails.
  • To avoid tracking mud onto the trails, bikes must have clean tires .

Sharing the Trails with Other Users

  • Yield to other trail users.
  • Ride single file, leaving room for skiers to pass.
  • Stay on the right side of trails when coming around corners.
  • Avoid riding in the middle of the trail as it is often soft.
  • Please stay out of the classic ski tracks.
  • Stay on your bike. Footprints damage the trail.
  • Be prepared to encounter dogs off leash on our dog-friendly trails.

Failure to abide by these rules may result in loss of daily ticket or season pass and other privileges.
