Another cool place to check out in Beijing is the Summer Palace. It's a cool little palace tucked away in the side of a hill. It's a great mix of classic chinese architecture and nature. There are also these cool canals that you can walk along (for an extra small fee).
If you want to check it out, just make sure you're ready for a lot of stairs! Your legs might burn, but the view is worth it~
This palace is surrounded by trees. If you go back up behind the palaces there's a fun little woodsy section you can walk around. Its actually kind of peaceful.
