Benjamin Loop is directional for bikers, and the direction changes approximately every four weeks. Please follow posted signs. The preferred direction from the Link Loop is clockwise (not that you have a choice, just be excited if that's the direction du jour). A moderate climb is rewarded with a swoopy descent through the pine trees that will have you feeling like Princess Leia on Endor (watch out for oncoming Stormtroopers). The are a few rocks and a little bit of exposure that may make this trail tricky for beginners.

Disclaimer

Trail closed to bikes on Wednesday and Saturdays. Please ride the posted direction.

      CW: Fast and fun. Worth 2 laps.
      CCW: No flow whatsoever. Skip it and ride Canyon loop twice.

      Day I rode this trail it was running counter-clockwise. Obvious signage on the trail. Fun ride. 1 or 2 tricky switchbacks. Intermediate rating is accurate.
