Dear friend,
Thanks for contacting Top China Travel! The best time to travel to Badaling Great is in spring and autumn, which is cool and sunny. Especially in autumn, the sky is clear and the air is crisp in Beijing. It is an ideal time that is called "Golden Beijing" by foreign and domestic visitors. The best month is in April, May, September and October.
If you have more questions, you can call the tourist center: 6912 1383, or 6912 1226
Any further request or question, please feel free to contact with us.
Warm regards,
Abby
