A 3200-meter-long glass skywalk, stretching around a cliff 200 meters above the ground in the eastern Chinese province Zhejiang, opened on Saturday to the public.

Saturday is the first day of China’s seven-day National Day holiday, when tourism peaks all across the country.

Due to the walkway’s capacity limit, tourists have to wait for three hours in line to be arranged to step on the 1.6-meter-wide glass floor. Despite the restriction, the glass walkway is still seen completely packed.
