The Onkaparinga River National Park is located south of Adelaide, best accessed by car, the park offers a good range of walking tracks. Starting at Gate 11 on Piggott Range Road, we picked up the trail for the Sundrews Lookout Hike, at the entrance to the park the signage seemed reliable to point us in the direction of the lookout but we never found it. At a fork in the path we had the choice of two trails, to the lookout or Sundews Ridge, we ended up taking both, still no lookout, I don't know where we went wrong. Regardless our time in the park was refreshing, we enjoyed the landscape with glimpes of the Onkaparinga Gorge and some birdlife. Along the way we discovered ruins of old buildings from the 1800s, in years gone by sections of the park were used for farming. Our hike took a little over an hour, roughly a four kilometre trail, much shorter than we had intended. Time saved was spent somewhere else in this beautiful part of Australia. In the carpark there were toilet facilites.
