Beijing Dawanglu Metro to PEK T2 at 11 pm?

There is no direct bus taking you from Dawanglu to the airport and at that time, most buses would have stopped operation. Therefore, MTR and airport shuttle bus are most suggested.

At Dawanglu MTR Station, you can take subway line 1 and transfer to line 2 at Jianguomen Station to get off at Dongzhimen, where you can take shuttle bus line 2 to PEK directly.

Or you can also take subway line 10 to Sanyuanqiao, where you can catch a taxi to PEK.

For the back journey, you can catch shuttle bus line 2 (Night Line) to Chaoyangmen Station, where you need to transfer to a taxi to the destination.
