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 Lille Zoo is free and houses about 350 animals representing 100 different species: monkeys, zebras, panthers, rare birds, etc.
The zoo is open on summer (until October 28) from 10am to 6pm on week (except on Tuesday), and from 10am to 7pm on weekends and bankholidays, in winter from 10am to 5pm everydays (except on Tuesday).
