      A network of mixed use trails on Thornhill. Please note when encountering horses, the MTB rider should yield to the horse rider. Yielding to Equestrians: At Thornhill, a huge part of the heritage is tied up in riding horses. Bikers often scare horses. We are less familiar to them than hikers, so use caution. We recommend that as you approach an equestrian you call out a friendly greeting from far away. Slow the heck down, too. You want to start talking from about 50-75 ft away if you can. Like I said, horses spook easily, so try asking how the person on the horse would like you to get by. Would they like you to get off and walk (this is great for horses that are really skittish) or should you pass slowly at the next safe spot?
      Primary Trail Type: All-Mountain & Downhill
      eBikes Allowed: No
      AKA: Grant Hill, Thorn
