The Grinder is a difficult trail that contains a mix of old-school hand built Galena singletrack and new-school machine-built singletrack. Certain sections are very fun to ride on a bike and other sections will make you question why you like biking.

It is recommended that bikers ride the west section of the Grinder from FSR 189 to Psycho Ridge for the most enjoyment. This section contains some of the most technical riding at Galena. The Grinder can also be used to access Mineshaft via Horsefly Hill.

Like all of the singletrack trails at Galena, the Grinder Trail is open to two-way traffic and shared use by hikers, horseback riders, runners, and bicyclists. Watch for and yield to others - on this and all trails. All Galena singletrack trails are closed to E-Bikes.

Access Info

Access from Horsefly Hill, FSR 189, Psycho Ridge, Mineshaft.

Disclaimer

The USFS has implemented the Big Wood Travel Plan which includes decommissioning many old mining roads in the area.

Adaptive Bike Info
aMTB 3 Rating: Major obstacles exist. You will not be able to ride this solo. Support rider needed.

Old-school hand-built singletrack between Horsefly Hill and FSR 189 poses significant challenges like off camber sections, skinny singletrack and steep bench-cut sections.

The new-school section of the trail from FSR 189 to Psycho Ridge offers a wider trail width but poses challenges in the form of frequent trail obstacles like rock gardens.

      West of FS 189 is in great shape. A couple down trees but easily bypassed.

      Don’t need suspension. Better on a gravel bike

      The Grinder is definitely fun. Appropriately named though since there are many punchy climbs, but downhill sections have decent banked turns. Went clockwise.
