Fat Biking

Winter Lift-Served, Downhill Fat Tire Biking

Spirit Mountain introduced winter lift-served, downhill fat tire biking to our operations during the 2015/2016 winter season.  With great success and a heck of a lot of fun, we will bring lift-access fat biking back for the 2016/2017 winter.  Thanks to the volunteers from COGGS and our Bike Park Crew for keeping the trails dialed-in all year long....enjoy! 

Begins:  Typically, Sunday's in early-January through end of winter season, weather & trail condition permitting. 

Hours:  10am-4pm

Cost:  Regular lift ticket price of $49 or a winter season pass


  • minimum tire width 3"
  • brakes for each wheel
  • helmets 
  • a seat/seat post and overall bike inspection is required prior to allowing any bike on a chairlift.  Inspection performed by Spirit Mountain
  • must abide by the Mountain Bike Responsibility Code, Rules of the Trail and Trail Code = SAFETY INFORMATION

Trails Open: Update for Sunday, February 26 - Our plan is to resume fat bike operations this weekend!  At this point in time, we would plan to have our integrated slopes of Juggler Joe & Timber Cruiser available for fat bike ops.  We will continue to evaluate Happy Camper, Candyland and Calculated Risk...but as of today, it is highly doubtful these trails will be in rideable condition for Sunday...unless we get that FOOT of snow from a rogue winterstorm coming through!?!  Regardless, come on our and enjoy the trails as it is always a good time for downhill fat biking here at Spirit!  Frosted Fatty Weekend is only a WEEK away!!

Please Note: on our integrated ski slopes, skiers & snowboarders have the right of way...bikers must yield to skiers & snowboarders while on the slopes.


Trail Head & Parking:  All fat biking operations roll through our Grand Avenue Chalet.  This includes lift tickets, mandatory bike check, etc.  Grand Avenue Chalet is located at 8551 Grand Avenue, Duluth MN
