Its a nice place. Its not really famous, i noticed that because i was the only foreigner today. They have a good collection of skeletons and eggs all in a huge place. Also isnt difficult to arrive, since 老汽车站 in Xixia you can get a little bus for 8 ¥, it takes just 40 minutes and let you inside the Park (the entrance its a little far by walk). I enjoyed a lot my visit.
