As China’s Mogao Grottoes brace for peak tourist season, new ticketing measures have been implemented to protect the ancient Buddhist site. There will be a maximum daily intake of 6,000 visitors by prior reservation, and group sizes will be limited to 200 people. Tourists can still arrive without a reservation, but with different pricing and itineraries. Reserved tickets are guaranteed a tour of up to 3-1/2 hours taking in eight caves and the site’s four museums. Tickets purchased on site will be for visits limited to about one hour and just four grottoes.
