Take a brisk walk or relaxing stroll by the canal Almost 65 miles long, the Canal de l'Ourcq opens out into the lake in Parc de la Villette, in the far northeast of Paris. There is a festive, family atmosphere, especially on the weekend. Quieter during the week, the canal is also popular with sporty types, who come to train in a green environment. The nautical space is reserved for pleasure and leisure pursuits: boats, canoeing and kayaking, inflatable boats, and more.
