The Mutianyu authority started to build blockage from Jiankou to Mutianyu on 30th March. The entrance at Watch Tower 20 was closed off. It is still manageable if you are willing to climb over the 60cm-high wall next to the entrance. The hike from Jiankou to Mutianyu now is becoming increasingly popular. It’s a pity that the doorway was blocked.
