The largest gate is the South gate, as in most historical China buildings. This is indeed impressive and therefore recommended. There are several shows throughtout the day and the buggy ride (80 RMB per person) round the wall with several stops was a great way to see the length of the wall, alternatively one can rent and cycle around. The most impressive part was the toilet at the entrance of south gate much similar to a 4/5 star hotel standard and decor.
