How long does it take to take children (three and a half years old) to play Yunlong Mountain?

Entering the mountain from the north gate opposite the museum takes about 15 minutes to reach a fork. I suggest you go left, because in about 15 minutes, you can see the famous scenic spots such as He Fangting and He Quan. At present, tickets for Yunlong Mountain 15 yuan package, including tickets for observation deck. You can have a rest and continue to take the children forward. After about 40 minutes, you can walk to the observation deck, where you can overlook half of Xuzhou City and the panoramic view of yunlong lake, the famous 4A scenic spot in Xuzhou. After the tour, you can go back along the original road.

I hope I can help you, O(∩_∩)O~
