Indoor and Outdoor Pool of Onex

A neighborhood pool for the whole family

Nestled in the Onex park, the municipal pool of Onex-Parc is one of those convenient places that quickly becomes a favorite when you have children. Inside, a large covered and heated pool awaits you all year round, sheltered from rain and cold. As soon as the nice days arrive, an outdoor wading pool opens for the little ones. You come here for a leisurely swim, a first swimming lesson, or simply to occupy a rainy afternoon without leaving the area.

What your children will discover

The covered 25-meter pool provides space to swim, play, and progress at their own pace. A small shallow pool (about 80 cm) reassures children who cannot touch the bottom everywhere and allows beginners to gain confidence. On sunny days, the outdoor wading pool (only a few centimeters of water) becomes the playground for toddlers, who can splash around safely while parents keep an eye on them in the shade.

What to do there and the atmosphere on site

The atmosphere is that of a community pool: simple, family-friendly, and unpretentious. You will encounter families from the neighborhood, children taking lessons, and swimmers coming to do a few laps. The indoor water is heated, making swimming pleasant even in the middle of winter. It’s the perfect place to turn a Wednesday afternoon or a gloomy Sunday into an easy outing without much organization.
