hi,

May I know how many days (at least) do I need to cover the following Great Walls in Shanxi - Guguan Pass, Niangziguan Pass, Ningwuguan Pass, Yanmengguan Pass, Pianguan Pass and Pingxingguan Pass? I intend to travel on my own and alone. Is it safe? Also how do I access to all these Walls? Pls advise on the transportation mode and ways.

Thanks.
