My husband and I caught the bus from the Xi'an train station. It was Y9 each, one way. It was a green bus with yellow writing on the side saying Xi'an train station <--> Terracotta Warriors, very easy to identify and the conductor let us know when it was our stop. It took about 50minutes and was very easy.
It dropped us off on the road and we walked through this odd complex to another paedestrian street running through the Warriors Museum complex. The ticket booth was difficult to find when we turned right, and then we had to backtrack for about a kilometre to get to the actual entrance to the museum. It was all relatively well sign-posted though. It was easy to ignore touts.
We started in Pit 3 by accident and it was bit underwhelming due to being only partially-excavated, however by the time we got to Pit 1, we were very excited. The detail and enormity of the complex is astounding. Even without an audio guide, we had a fantastic time and got enough information out of the Chinese/English information boards dotted around each pit. It snowed the whole time we were there too, which was a novelty for us.
To get back to Xi'an, we walked back out to the main road and hailed down the same green bus with yellow writing going in the opposite direction. Don't believe your hotel if they tell you it's too difficult to get there without a driver! Our hotel tried to sell us a driver for Y1000 return! We spent two hours at the Warriors, you could easily spend hours more if you read every bit of information and looked at all the sites in the Exhibition Centre.
We can't wait to go back again in ten years and see what progress has been made with the excavation!
