I visited this place during winter. It was rather scenic. I guess it will be even more beautiful during spring or summer. However, this place does not leave much impression on me as I have visited a number of natural scenic places (i.e. great wall etc). Can visit but not a must visit place. It is important to get a good tour guide to explain to you on all the history of China so that you can better appreciate this summer palace.
