Technical Downhill. Nasty. You can fly down this thing but you better bring your A-Game.A few switch-backs on the way down. Set your suspension wide open. When you see your line, stick it. Too steep to change your mind mid-ride.

Access Info

Access this trail via halfway through Upper Tilley. Assuming that you are going counter-clockwise, after the downhill section, instead of a left to complete Upper Tilley Loop, turn right. There are signs located at the turns.

       Great trail. Extended rock sections all the way down, maybe 75% of the trail. Multiple technical lines to choose from on the way down, and possible to bomb. Anywhere from 6 to 18 inch drops / rolls along the way. Occasional tight turns while on rock faces. Not excessively rutted (as of Oct '19). If you can ride JM in Oakland, specifically the Chaparral trail, this is comparable, and maybe slightly less chunky.
