Comments: A challenging but rewarding ride. The climb up South Gate Road has several spots where it flattens to give relief. The descent down North Gate Road has it's twists, particularly several hairpin turns near the start. The climb on Morgan Territory Road is largely shaded and an adjacent creek will provide inspiration during Winter and Spring. The first half of the descent on Morgan Territory Road should be taken with caution. The road is a single lane in spots with tight blind corners. The bottom half of the road is wider and the sightlines are better.
