Gucun Park is a large park up north in Baoshan Qu, with its own metro station on Line 7. Take Exit Two. The space gets really busy on the weekends, with families enjoying the lake, flying kites on the green space, and riding roller coasters. Watch out for the sightseeing train that races around the park. Also, lots of 3D dinosaurs / haunted houses here. You can also rent a boat to pedal for a few hours, or seek out some hidden spots that look like a jungle. Entrance is 20rmb, and activities will cost 15–50rmb. The parking only seems to accept cash. Open 6am to 6pm.
