This park, Lille's largest (60 hectares = 123 acres) and most visited, brings a breath of fresh air to the city.
Encircled by the Deûle canal, the park includes the Bois de Boulogne Woods (which surround the ramparts of Vauban's Citadel) and the zoo. The Bois de Boulogne Woods are always open to visitors. There are some remarkable trees there, such as a Montpellier Maple, a Corsican pine and even a Giant Sequoia.
The Zoo houses about 400 animals representing 100 different species: monkeys, zebras, panthers, rare birds, etc.
The zoo is open in winter everydays (except on Tuesday) from 10am to 5pm, in summer everydays (except on Tuesday) from 10am to 6pm on week and from 10am to 7pm on weekend.
