Wow, amazing hike into the gorge. It was around 2.6 km to the end and it took about an hour or so. The last 1.4 km was quit quick. The hike is not that hard or tiring. Lots of little flies flying around you but didn’t bite, just annoying. We used trekking poles and that helped a lot. Unfortunately, it rained on the way out. The multiple shelters can in handy. The path is relatively new but beware it can slippery. Well worth the 30 RMB entrance ticket.
