Fat Bike Trails

Fat biking is a fun alternative way to explore our winter trails at the Cross Country Ski Area.  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.

What is Fat Biking?

Fat bikes offer a fun alternative way to explore the trails.  Fat bikes are just like a regular mountain bike with extra fat tires which are specially 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 at all times during fat bike riding, as well as wearing appropriate winter gear.

Fat Bike Tickets and Season Passes:

  • A daily fat bike ticket or fat bike season pass is required to ride the trail at the Cross Country Center.
  • Fat bike day tickets and season passes are a separate product from the regular 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 the Alder Creek Adventure Center during the season. Pass holders are required to scan their pass at the Alder Creek Adventure Center when accessing the trail system.
  • fat bike Season Pass holders are welcome to ride starting at 7am, when conditions permit trails to be open. 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.  Rental is $34 for up to 2 hrs. (A fat bike daily ticket is an additional $15 for Members, $19 for public).

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

Fat Bike Trails

Fat bike trail access can change daily and even hourly depending on conditions. Fresh snow and warm temperatures can lead to ‘no fat biking’ days or times, or reduced access. Visit the daily grooming report before leaving home, and check with staff on arrival as conditions change.

Fat bikes are allowed on the following 7km of machine groomed ski trails daily when conditions permit (see “Fat Bike Trails Open or Closed?” below)

  • Piece of Cake
  • Cup of Tea
  • Silverstreak
  • Dogonit
  • Aspen
  • Rust Never Sleeps
  • Upper Big Dipper
  • Lower Boot Hill
  • Dogs in Space
  • Crazy Horse between Dogs In Space entrances

Fat bikes are also allowed on all 11km of snowmobile packed ‘singletrack’ snowshoe trails daily when conditions permit (see "Fat Bike Trail Open or Closed?" below).

On Tuesday and Sunday mornings fat bikes will be allowed on all Home Range and Sunrise Bowl Trails (40km) before 11am when conditions permit. Riding is not permitted on the Euer Valley Trails or on the Interconnect to the Downhill Area.

Fat Bike Trail Open or Closed?

  • Fat biking is not permitted if conditions become too warm, soft or wet. We want you to have a good time out there!
  • Visit the daily grooming report before leaving home, and check with staff on arrival as conditions change.
  • As general rules:
  • If there is more than 6 inches or fresh snow or the air temperature is forecasted to be above freezing, conditions may be too soft for biking on the trails and fat biking will not be permitted.
  • 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.

Rules and Etiquette for Fat Biking

  • Riders must have purchased a fat bike daily ticket or fat bike season pass to ride within the Cross Country Ski Area boundary.
  • 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 only ride on designated fat bike trails; no biking on non fat bike trails or off-piste.
  • Only purpose-built fat bikes are permitted! Bike tires must be wider than 4 inches and have pressure of less than 10 psi.
  • Riders may not ride if tires are leaving a rut deeper than one inch
  • Riders must only ride with clean tires to avoid tracking mud onto the trails.

 Sharing trails with other users

  • Riders yield to all other users, stay out of the classic ski tracks (the two parallel lines groomed into the snow), and give skate skiers a wide berth.
  • Riders should ride single file leaving room for skiers to pass and stay to the right side of trails when coming around corners.
  • Stay on your bike. Footprints damage the trail.
  • Riders should be prepared to encounter dogs off leash on our “Dog Friendly Trails”.

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