definitely would recommend this place. Buy the 100rmb ticket at the gate. But again plan before the time or atleast have two days free... I thoroughly enjoyed the Meiling Tomb- one big beautiful garden with various statues.. Its really big so should take you about 1-2hours even longer depending on how often you stop and take in the views. Walking to the San YatSun mausoleum from here is about 1-1.5km so no need to take a shuttle. But again the park is great and there are a lot of trees that are nice and cool with many pathways so even if you just want to go walk around you can. Some sights do not require a ticket even. But this is a MUST visit when in Nanjing.
Extremely beautiful during fall!
