I went to the Zhongshan Mountain scenic park. Bought my ticket 100rmb which entitles you to visit the 4 main spots Meiling Palace,Meiling Tomb, Purple Mountain (Sun Yat-Sen Mausoleum) and the Linggu scenic area. I would definitely recommend this option. Everything is within walking distance from each other so no need for the bus ticket and DO NOT make use of taxi's driving around there. They are over priced. The mausoleum is definitely the high light but beware its extremely crowded. Even though I went on a Tuesday and it was about to rain... But definitely worth it.
