Accessed from the Upper Fear & Loaming Trailhead, Gnarstow is an extremely steep & technical DH descent with alternating difficult option/feature lines. There are multiple mandatory steep chutes that require a high level of skill. Alternate routes are available in places but are much steeper than anything you'll experience over at Fear & Loaming.
You'll encounter a few mandatory jumps along the way. SCOPE THE ENTIRE TRAIL BEFORE RIDING AT SPEED. Expect loose rocks/boulders and variable, unpredictable conditions.
Trail terminates at Drift Creek Road, far away from Fear & Loaming.
Access Info
Park at the Upper F&L Trailhead, 1/4 mile down Zone 1 of F&L, make a left at the Gnarstow sign and cross the road. The trail terminates at Drift Creek Road.
