Paris has a notoriously short supply of green space, especially in the north. That makes this ten-acre park on the grounds of a former train station depot all the more delightful. The expanse is supposed to double in size by 2017, with a new residential neighborhood planned for its borders. Aside from a skate park and a basketball court, there are several playgrounds and enough stylish chaise lounges to linger under the shady willows. From the belvedere, you can even see the Eiffel Tower.
