TTFs on TrailBerm, Drop, Jump, Rock Face, Rock Garden, Skinny
THE most technical trail in the Aldefer/3 Sisters network and for good reason. Test and build your technical skill with this short but steep up-and-over trail that runs through a notch below south Sister. Typically ridden West to East, the trail starts with large slabs and boulders to a series of ultra tight switchbacks choked with rocks. Only the most skilled and technically adept riders will clean these sections to the high point. \Rolling down the other side, drops, berms, ledges and more tight switchbacks will test the very best. No dabs and you are the King of the 3 Queens. Bring your "A" game to get'er clean.
