The summer palace is one of the top places to visit while in Beijing, with that being said it is also an extremely crowded spot during the spring holiday. When visiting do not expect to receive the royal treatment. The bathrooms are few and far between and not well maintained. The food is scattered in small stalls and restaurants which will overcharge. Be sure to bring your own food and water when visiting and be ready to walk a lot. The main entrance will take you around the lake while the other entrance will take you up and through the mountain so be sure to check before you enter if you are not up for the uphill climb. Still, it is an amazing place with lots of history and a must see place in Beijing.
