This amazing trail system was started by miners 50 years ago, and today they are maintained by Sheep Mountain Lodge Sheep Mountain Lodge owner Zack Steer. Zoom down Thriller on your mountain bike, enjoy a picnic with a view at the top of Corkscrew, search for a geocache site or come berry picking in the fall. There are 12 miles of maintained trails, which are groomed for cross-country skiing in winter. Peak blueberry season is from Aug. 15 to Sept 10 and the low bush cranberry is peaking all of September. On weekends during these times, there will be as many as 40 pickers on the trails. The “bucket brigade” Zack calls the Anchorage folks, mostly Natives, who come to harvest their wintertime berry supply. The trails are on public land, and can be accessed at Sheep Mountain Lodge or at the public airstrip off the highway. The Steer’s ask for a wintertime donation of $5 to offset the costs of grooming the trails.
