The city wall of Xian is a nice and calm getaway from the hustle and bustle of the fumed streets. Here you can go for a leisurely stroll, and enjoy great views of the city. You will spot things you don’t see from the street level, and there are also marvels on top of the wall to have a look at. My only regret is that I only walked parts of it, and not the entire length. If you do decide to explore the wall in its entirety, make sure you set aside plenty of time as Xian is a big city and consequently the wall is long. It is also worth noticing that you can enter at several different places along the wall.
