Clissold Park

If the sun is out and you don't feel like paying for one of the lounge chairs in Green Park (groan), hop on a northbound bus to Clissold Park. The centerpiece to idyllic family neighborhood Stoke Newington, the Victorian park houses four bodies of water, community animal enclosures, and the historic "House at Clissold Park". On sunny days it will be awash with the young taste-makers of nearby Hackney and the cozied up families that seemed to colonize the neighborhood in the past decade. The animal enclosure alone would make a memorable — and totally free - day out with children. On display are rare deer and grumpy goats. For some cardio, join the joggers making their way around the park's tree-lined circumference, or head to the tennis courts.
