The amazing park des Buttes-Chaumont has two playgrounds for children to enjoy. One of them is a smaller play area specifically for toddlers with a sandbox and a carousel, where they can ride ponies, as well.
And there is a larger area for older kids, a mountain to climb, horse riding and seating for the adults. Be aware of the uneven terrain of the park, which makes it more difficult to go with a stroller.
