      Generally handdug/hand maintained trails. Some access issues, be mindful of hikers and horsepeople (centaurs). Most climbs are of the paved/fireroad variety, most descents are a mix of loose rock, fixed rock, and good dirt. Gets dry in the summer. High elevation trails are clear May-October, bring plenty of water.
      Primary Trail Type: All-Mountain & Downhill
      Shuttleable: YES
