If you're planning to visit this scenic area, you first need to consider your physical condition. If you struggle to even climb to the ticket gate, my advice is not to climb. Of course, if you're determined, you can manage, but you'll likely have to take a cable car down. I recommend going in the early morning, when tea is at its best. If you go in the afternoon or evening, you'll be exhausted and freezing at the top, and finding accommodation will be a real ordeal. Also, the sea of clouds is often invisible; the overall scenery is best appreciated by an NPC.
