After a powerful earthquake forced its closure two years ago, part of the Jiuzhaigou National Park in southwest China's Sichuan Province will reopen to visitors on Friday on a trial basis, local authorities said Monday.

During the trial period, the park will open from 8:30 a.m. to 5 p.m. daily and receive no more than 5,000 tourists per day. Tourists will need to buy tickets from designated websites before visiting the area, according to the park's management bureau, with all visitors required to join a tour group.

On Aug. 8, 2017, a 7.0-magnitude quake forced the closure of the Jiuzhaigou National Park, a UNESCO World Heritage site famous for its spectacular waterfalls, lush forests and serene plateau lakes. The Jiuzhai Huanglong Airport also halted service. After more than two years of rebuilding, 85 percent of the park's area is now ready to receive tourists, according to the bureau.
