Description

The Benjamin loop was new as of May 2011. It starts as a spur off of the farthest point on the Canyon Loop. This new trail was built by large groups of volunteers, and features significantly more interesting terrain than the Canyon Loop. This trail winds through thick forest, and in places is cut right into the side of rock faces that required major engineering feats to build.

The new trail flows very well, and offers a nice 4 mile addition to the original trail.
