Three people fat biking along a snow trail

Fat Biking

Fat Tired Freedom

We were the first ski resort in the United States to embrace and endorse winter fat bikes on our Winter Sports Trail System. In Alta, Wyoming, biking is a year-round sport, and fat bikers can enjoy access to over 9 miles of groomed Nordic track.

Fat bikers must purchase one of the following to ride our Winter Sports Trail System: a Full Mountain Lift Ticket, Winter Season Pass, Nordic Trail Ticket or a Nordic Season Pass.

Purchase Tickets

Please check the Lifts & Trails Report for the most accurate information and trail status. Please note that Fat Biking is not allowed if we've received more than 3 inches of fresh snow. 


  • Helmets are encouraged and recommended.  
  • Bikes should yield at all intersections. 
  • Bike Lane: Ride to the left of the classic track and yield to all skiers. Stay to the right side of the trail around corners in case of oncoming skiers. 
  • Do not ride on the classic track. Only ride on designated shared cross-country trails. 
  • Ride Rick’s Basin Loop and Quakie Loop counterclockwise only. This is the best direction for the least amount of hill climbing and the best downhill. 
  • Please let the track set–up until 10:00 am on the mornings when the track is groomed. 
  • Do not ride in soft conditions. Hard-packed conditions on trails with 2″ of new snow are allowed, but more than 2″ makes climbing and descending very difficult. During a snow cycle, 12″ or more with freshly groomed trails can be too soft. If you are leaving a rut, the trail is too soft to ride. 
  • Fat bikes must have tires that are 3.7″ or wider. 
  • Fat bikes need to keep tire pressure between 3 and 7. You should be able to crease the sidewall when squeezed.  If you are leaving a rut, reduce air pressure in your tires. 
  • Standard mountain bikes and e-bikes are not allowed on trails. 


  • Nordic Trail ticket or Season Pass is required to access the Winter Sports Trail System.  
  • Hours of operation: 9:00am – 4:00pm daily. 
  • The Winter Sports Trail System will be closed when it snows more than 3″. 
  • Nordic trails are typically groomed, and the classic track set, on Tuesday, Thursday, Saturday and Sunday, conditions permitting. Please check the Lift & Trails Report for updated grooming information. 
  • Resort boundaries are not marked. It is recommended to stay on designated trails. 
  • Trail system is shared with Nordic skiers, snowshoers, and fat bikers. Treat other users with courtesy and respect. 
  • Keep the volume on your headphones at a reasonable level. 
  • Dogs are not permitted on trails. 
  • Over-snow vehicles may be encountered at any time, please give them plenty of space.  
  • Teton Pass is closed until further notice. Please visit the Getting Here page on our website for more information on how to update your travel plans accordingly.
