Campers sleep perched on cliff face

More than 100 backpackers slept in their tents while perched on a 1,700-meter cliff face after they set up tents from Friday to Saturday along a plank road that hugs Laojun Mountain in Henan province.

The spine-tingling campsite, however, rewarded them with breathtaking views of the sea of clouds that fills up the valley below like an expanse of water.

Xu Lei, one of the backpackers and an organizer of the trip, said that for the first time, they moved campers from the bottom to partway up the mountain to get a better view of the sea of clouds and the sunrise.
