The Durrance Loop is a new winter-only groomed trail accessible to Cross Country skiers, dogs, and Fat Bikes.  The trail is available as part of a one-season trial in winter of 2014 made possible by the Sawtooth National Recreation Area and the Blaine County Recreation District.  The trail is accessed by a trailhead located on the west side of the SNRA parking lot at the southern gateway to the Sawtooth National Recreation Area just 10 minutes north of Ketchum, Idaho on Highway 75 and joins the other winter trails groomed and maintained by the BCRD as part of the North Valley Trail system.

The Durrance Loop is intended to offer great cross-country skiing as well as access for an increasingly popular form of healthy, active recreation: Fat Biking.  Please be mindful of the critical conditions of use and other information below so that we can ensure great skiing and safe, complementary experiences for all users.  The Trail requires a valid BCRD Nordic season pass or Nordic day pass.  Fat Bikes are NOT allowed on any of the other, existing BCRD cross-country and snowshoe trails under the BCRD season and day pass, however, Fat Bikes are welcome on the groomed, 20 mile Wood River Trail (a.k.a. the 'bike path') throughout the year with no fee required.

What is a Fat Bike?

  • All terrain bicycle
  • Provides additional float & traction in soft conditions
  • 3.7-4.7 inch wide tires (2-3 inches wider than a mountain bike tire)
  • Can be used on snow machine trails, Nordic groomed ski trails, mountain bike trails, city streets or paths, beaches and other packed snow surfaces.

Fat Biking Code of Etiquette

  • Riders must purchase and display a BCRD Nordic day or season pass when riding on groomed trails where passes are required
  • Trail access for Fat Bikes is dependent on conditions and riders should check the daily grooming report at winter for detailed trail access information
  • Purpose built Fat Bikes only!  Both tires must be wider than 3.6 inches and tire pressure must be less than 10 psi.  No exceptions!
  • Fat Bikes yield to all other users.  Stay out of the classic ski tracks and give skate skiers a wide berth.
  • Stay on your bike.  Footprints damage the trail.
  • If you are leaving a rut deeper than one inch or having a hard time riding in a straight line, or pushing your bike, then the snow is too soft and you should not be biking on the trail.
  • Be respectful of others - slow down, smile, and say 'hello'.
  • Be prepared to encounter dogs on shared trails.
