      O-Hill is owned by the University of Virginia and represents some of the most aggressive trails in the Charlottesville Area. Its location along the RTF makes it a popular destination as part of an in-town mountain bike ride. Be prepared for steep, rocky climbs and descents. Trails cross each other all over the mountain, making it relatively easy to make several laps up and down the mountain without repeating many trails.
      Primary Trail Type: All-Mountain & Downhill
      Access Info:
      There is parking at the upper gate on the Upper Perimeter. Also entrances using the Rivanna Trail from Fontaine or Ivy road.
