Et si, pendant deux heures, les enfants pouvaient devenir pompier, vétérinaire ou même chef de chantier ? "Quand je serai grand", nouveau parc pour enfants installé à Mours, près de L’Isle-Adam dans le Val-d’Oise, revisite ce principe en offrant une mini-ville entièrement pensée à leur échelle. Ici, pas de manèges : les enfants de 1 à 11 ans déambulent dans divers décors et choisissent les métiers qu’ils souhaitent expérimenter au cours de leur session.
The program features several spaces recreating places that children know in daily life. They can step into a fire station, a veterinary clinic, a hospital, a supermarket or a school and take part in missions tailored to their age. Other careers are available, such as pizzaiolo, hairdresser, shopkeeper or site manager. The principle rests on role-playing: children handle, collaborate and practically discover the tasks associated with each profession.
A standard session lasts two hours, and each child can choose several experiences. Tuesday works differently, with a plan marketed as unlimited between 4 p.m. and 8 p.m. The online booking is highly recommended, as spots are limited for each time slot.
Admission is €13 per child aged 1 to 11, with an additional €5 for each accompanying adult. A ten-entry pass is also available at €109, valid for one year and shareable with family or friends. Children under 1 year old are admitted free. Drinks and snacks are available on site, and nearby parking is free. Socks are mandatory for everyone.
A wonderful family outing idea, cozy in winter and breezy in summer, for playing, touching, and mimicking...
