Tri-Forest Snowmobile Trails Conditions Report

General conditions:

 Trail grooming is completed weekly based on weather and other limitations. Please see individual trail grooming and conditions report (below).

Know before you go! Visit http://shastaavalanche.org/ for weather and avalanche forecasts and snowmobile trail conditions.

Welcome to the Tri-Forest Snowmobile Trail Conditions Report. We have four snowmobile parks that are linked by over 250 miles of Groomed Trails over three forests. The trails are maintained by two groomers. One is stored at Pilgrim Creek Snowmobile Park (Shasta-Trinity National Forest ) and covers between Pilgrim Creek and Deer Mtn. The other groomer is based at Four Corners Snowmobile Park ( Klamath National Forest ) and covers between Four Corners to Door Knob / Medicine Lake area.

Depending on snow conditions, trail grooming usually begins in December or January and usually ends by April.

Grant dollars from the California State Off-Highway Vehicle Fund financed the development and maintenance of these snowmobile parks and trail systems.  Trails are maintained and groomed by the Forest Service, volunteers, and members of the Mt. Shasta Sno-Mobilers.  Visit their web page for more local snowmobiling information.

The Trail Conditions Report is updated as we receive information from the Shasta-Trinity NF and Klamath NF groomers.
