Travelling from Juyongguan to Badaling Great Wall

I think you should contact your travel agent to change your package. This is much easier. There is bus from Juyongguan to Badaling by Tourist Bus Line 1, but you need to walk about 2.5 kilometers to the entry of Badaling after get off the bus. You can get back to the city by bus 877 and the Tourist Bus Line 1. Please remember the last bus from the great wall is at 16:30 from November to March.
