Instead of sitting in the airport during your layover, head to the Great Wall on this guided tour. Visit the Mutianyu section of the wall, which is the best possible option from the airport. Once you arrive, choose to hike up or ride the cable car instead. Plus, a winter jacket will be provided free of charge in winter.
Take advantage of your layover in Beijing and visit its top attraction
Enjoy lunch near the Great Wall (at your own expense), time permitting
Tour times are based on your arrival and departure times
Make sure your layover is long enough before booking (tour time is 5 hours)
