For green open space, just a short walk away is Millfields Park, Hackney Downs Park, Clissold Park, Springfield Park, the Lee Navigation (canal walk), Middlesex Filter Beds Nature Reserve, Woodberry Wetlands nature reserve, and the Stratford Olympic Park, to name but a few.
Hackney Marshes is a lush green belt 10 minutes on foot and is perfect for a dog walk, summer picnics, and even a visit to see the horses that live there year round! Using the overground you can also visit Walthamstow wetlands nature reserve and be in Epping forest with 20-30 minutes.
