Combo ticket

Yes, the museum is inside the City Wall, and the museum is near the Yongning Gate (South Gate) of the wall. After you visit the museum, you can atop the wall through the Yongning Gate and rent a bike. One thing to remind is that the two sites are seperately ticketed, which means there is no combo.

Thank you, I've got another question. After I'll rent a bike I plan to go later to visit Terracotta Warriors, I read somewhere that one of the buses I can take to get there is next to Railway Station. Can I return bike in the area of Railway Station and still get the deposit? And how long will take the bus to Terracotta Wariors. It is possible to go there in right time and return to South Gate (I'm going to have in this area hotel) without any rush? Than you for your answer :)

Railway station is close to North Gate of the City Wall. You can return the bike and get your deposit there.

After, get down the wall and walk to the east square of railway station to take bus 306 (You 5) to Terracotta Warriors. It takes about 1.5 hours on the way.

After the visiting, you can still take the 306 back to the railway station. Then take a city bus to the South Gate. One day for City Wall and Terracotta Warriors are enough. No worry.

Thank you, it was really helpful :)

now there are combo ticket， you will save 29 RMB to visit Xi'an beilin Museum and City Wall
