In the village of Changé, BMX enthusiasts will be able to go to the Pump Track for free, as will snowboarders at the Skate park next door.
In addition, many parks offer fun activities: Papéa parc, an amusement park of modest size that allows you to spend a pleasant day with the family on the rides (10 min. From La Cointise), the water parks (Atlantides in Le Mans with its large slides, its wild river and its swimming area; or Sittellia in Montfort le Gesnois, more modest but also very pleasant); and finally the traditional laser game areas, bowling, trampoline park, paintball, etc. which you can easily find on the net.
Find out more about Papéa Parc, Les Atlantides and Sittellia on their website.
