Absolutely horrible place. I came across it accidentally while leaving the Great Wall of China and I'm disguisted with what I saw. Bears are kept in disguisting, large holes in the ground, there is no greenery in their enclosures, no sight of water, no proper fences so tourists throw rubbish in there. One of the bears had a piece of plastic hanging out of his butt, another one had an injury in his eye. Some of the bears were displaying abnormal behaviour, such as head banging or staying motionlessly in a strange position. At some point an employee casually walked into one of the pits to sweep the rubbish thrown in by the tourists. As soon as he went in, all the bears climbed up on the platforms in rush. It seemed like they were afraid of him and tried to get away from him as far as possible. Never seen anything like it. When he finished and started heading towards the exit they immediately got back down. Most likely they're abused by the staff.

Absolutely disgraceful place that ruined all the fun we had on the Great Wall. We'll definitely never go back to Badaling after seeing this.
