How to get to getu cave in Guizhou from beijing? Is there any public transport other than flight?

Yes, you can use train service. At Beijing West Train Station, take a train to Anshun first. It takes 29h or longer. Upon arrival, take a bus at Anshun Bus Station to Ziyun and then transfer to another bus or rent a van to your destination.

Beijing-->Guiyang-->Anshun-->Zi Yun-->Getu Cave. Beijing to Guiyang is 28hrs by train 3.5hrs by palne. Guiyang to Getu Cave is around 4.5hrs by public transportation. Hope you enjoy your trip!
