The hike isn't demanding, you can climb the stairs or go up the winding road. There is a pagoda in the cave where you can go on the way too. Nice views and a bit away from polluted Hai Phong.
Really enjoyed this trail once you're on it for maybe 10 mins it gets even better as all the tourists aren't interested anymore. You get to see a wide variety of terrain and ultimately end up at the bridge right at the 52.
