Direct Bus from Dongzhimen Outer Bay to Mutianyu Wall

Hi there,

I've been reading blogs in the past few days and most of reads say the direct bus from Dongzhimen to Mutianyu Wall is no longer operational. However, seeing response of Ryan to Adrian's query makes me confuse again but looking at the response date, it seems pretty recent.

Sorry for asking again, bus is it really in operation now? I am coming over to Beijing in the next few weeks and I prefer to go to Mutianyu through this direct bus transit. Is it still located at Outer Bay? How many hours is the travel time one way?

Thanks a lot and appreciate any feedback :)
