A well established trail system which seldom used. Tight and technical. Maps aren't perfect and many trails merge and split. It runs along a creek with swinging bridges. Ride only green and red. Yellow is for horses. All but one section of the trail system is machine built and has a good flow to it. The one remaining hand built section is an awesome rolling section with several bridges. The entire system is rideable by any level rider. If you want more challenge pedal harder.
