The park is proud to offer multiple-use trails to serve a variety of visitors and outdoor enthusiasts in fulfilment of the Idaho Department of Parks and Recreation’s mission to; “Improve the quality of life in Idaho through outdoor recreation, and resource stewardship.” We are innovators in outdoor recreation, committed to excellent service and resource stewardship. We foster experiences that renew the human spirit and promote community vitality.

In order for all to safely enjoy the trails they share, it is essential to extend courtesy to other users.

  • Be aware of trail etiquette and yielding to other users
  • Be mindful of any one-way trails.
  • Those on snowshoes and fat-tire bikes need to be mindful of and stay off the groomed ski track.
  • Fat-tire bikers should have a minimum width of 3.7-inch diameter tires with pressure of 5 P.S.I. or less. Also, be aware of trail conditions– Ride on the most firm part of the track.  Do not ride in soft snow conditions; if you leave a rut deeper than 1 inch, it is too soft.


The park offers a variety of educational and experiential programs on Saturdays throughout the winter. Self-guided activities for kids, such as the Jr. Ranger and Jr. Snow Explorer Backpack programs are available every day!


  • Motor Vehicle Entrance Fee: $7 per vehicle, Idaho State Parks Passport, or Annual Pass
