Amazing hike. Did it as a very long day hike, took ~9 hours. Didn’t see any other hikers except for on the out-and back to the Causeway. Saw a couple friendly bow hunter groups on horseback. Amazing weather, mid-Sept is a great time of year to explore this area as the aspens have started to turn. A bit tricky to follow the trail along the Chinese wall, you’ll lose it and find it again if you stay in the general direction.
