Approaching the park from Sceaux means you enter the estate via a set of pretty blue doors outside the Petit Château. This attractive mansion was acquired by the park’s first notable owner, Jean-Baptiste Colbert, for use as a guesthouse in the early 1680s. From here, a short avenue leads you straight to Sceaux’s crowning glory, the spectacular formal gardens designed by Versailles’ landscape architect André Le Nôtre. Gently sloping away from the main château, they’re a masterful combination of symmetry, topiary and fountains.
If you're looking for a wilder and more secluded picnic spot, follow the Grand Canal to the Plaine de la Patte d’Oie, where you’ll find plenty of grass to spread out on. If it’s delicate cherry blossom you’re after, head to the Bosquet Nord, which usually bursts into colour in April. There are plenty of maps to help you get around.
