The Loop Trail becomes a rocky dirt singletrack as it skirts around the side of the cliffs. This is the most technical section of the trail by far. It's not hard, and you can still flow, but it definitely requires you to pay attention.

You get sweeping views of Red Rocks, the ridgeline, and Denver the higher you climb. The path is a fairly easy dirt singletrack that is exposed to the sun the whole way. The Castle Trail runs the full length of Mount Falcon Park and takes you by multiple ruins.
