The 10th arrondissement:

The 10th arrondissement of Paris centers around the Canal Saint-Martin and the restaurants and cafés which line its banks. Part sleepy faubourg — as suburbs were called in 18th century Paris — and part industrial center, the 10th arrondissement has lately enjoyed the benefits of both the booming nightlife scene in the neighboring 11th, as well as the Parisien cycling and roller-blading boom. The streets lining the canal become car-free for the later half of the day each Saturday, and all day on Sundays for your cycling and strolling pleasure.

There is another, more bustling side to the cosmopolitan 10th, however, as the location of two primary entry / exit points for the city, in the form of the two great train stations Gare du Nord and Gare de l'Est.

One final focus to the 10th is the historic Place de la République in the far south of the arrondissement, its many bars, restaurants and cafés.

The 19th arrondissement:

Situated on an immense steep and chaotic space, the park of Buttes Chaumont evokes the magnificent Baroque spirit of the Second Empire.
All along its five kilometers of paths and walks, there are many panoramic view points. The surprise effect is derived from the unexpected spaces and from the dimensions, unusual for the 19th century, of the components of the landscape.
