Grassy-Briery Professional Review and Guide
"A difficult ride that takes in a portion of the Flatwoods, then heads off to explore the more remote sections of Grassy and then Briery Creek. You’ll find it a mixture of sandy, rocky trails and smooth forest trails.
There are stream crossings, technical climbs and at least one real teeth-rattling descent. The ride surface is 9.8 miles of double/single track. Highlights include rocks, roots, stream crossings, sand, waterfall, winter views, and whoops."
