Anybody in Flag on a mountain bike can tell you how to get there.
Good luck finding detailed descriptions of the aforementioned trails, they are local's secret.
Just keep riding around and you'll find enough loops to keep you going for days. Keep your bearings on the Peaks and it is near impossible to get lost. If you need a guide, get cosmic ray's book. Get it at Cosmic cycles on your way out, you'll see it at the corner of beaver and fort valley road. At 10 miles, best quick loop in town.
