Indian Gulch 50 mile loop. This is a 50 mile loop ride. Leaving from the fairgrounds this route winds its way through the rolling Hills and countryside west of Mariposa. The road conditions vary from nicely paved big sweepers to a patch quilt of repaired potholes but the vistas are beautiful. Plan on a 2-hour ride. Bring everything you need because there are no stores or services on this route.
