Changfeng Gongyuan Park is a cool place which isn’t mentioned in any guide books I’ve seen. Luckily, I met a guy who has been to Shanghai several times and has native friends here. This place is a large park with a lake in the middle where you can hire electric boats for an hour at 60 CNY + 100 CNY deposit. Come here on a sunny day and bring a music player and some drinks. Also don’t forget to bring your camera as the view is amazing. You will be able to capture the skyline of skyscrapers which line Shanghai.
This place isn’t very well known to foreign tourists. While we were there we didn’t see any at all. It was packed with people from mainland China.
