Went recently on a sunny Saturday afternoon. Weather was great so walking around the area was pleasant. There are some inclined rock pathways and stairs, it wasn't so bad though. Saw lots of kids (and even people bringing baby strollers) to the scattered picnic/bench areas in the resting spots on the way up. What was also quite an experience is exploring the area outside of the main gate, to the left, where the street was paved very neatly and there were wineries, European-like mansions, streams/lakes, tall rustling trees, farms. Felt as if we stepped out of China. This walk led us to the other entrance (East Gate I think), which gave us the option to take a nice wooden platform walk through a grove of trees, or to go back to the Basilica area by stone paths. To get there we took Line 9 to the Sheshan metro stop. That took quite a while from the city center. Then right outside of the metro there is a metered taxi queue (which is really practical as I stay away from unlicensed taxis), and it cost about 18-20 rmb to get to the park. I used the smartshanghai app to show the taxi driver the location in Chinese, and used the maps.me app for navigation.
