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.

      Recent work on this trail is a great example that you CAN do trail maintenance/re-work to a challenging and natural trail without completely changing its character. The experience seems pretty much intact compared to riding this trail before the forest management work that took place over the past year.

      If this trail taught me anything, it’s that I am not one who can corner hairpin switchback turns well. That said this was a pretty cool trail and one I’d love to get better at.

      We hope you've been enjoying Trailforks!
