Shanghai Binjiang Forest Park is located at the city's northernmost edge, where the Huangpu River meets the Yangtze River. It is the closest forest park to Shanghai's downtown area — but it's still a bit of a trek. This is a half-day sort of outing, but it's actually quite big and spacious, and it's the best, closest option if you're looking to spend some time around some greenery. It's pretty well manicured with lots of different ecological areas, gardens, and wetlands, with walking paths throughout the area.
