What are the various options to travel from Guilin to Zhanjiajie, Hunan? thanks.

I am afraid that there is no direct transport. There are two modes of transport for you.

Take a bullet train to Liuzhou from Guilin Railway Station (about 1 hour). Then, take a train to ZJJ (about 11.5 to 13 hours).

Or, take a bullet train to Changsha South from Guilin Railway Station (about 3.5 hours). Then, take a bus to ZJJ (about 4 hours).
