Cossy Pool in Nyon: a family outing that feels good

An aquatic break in the heart of Nyon

The Cossy Pool is the typical address for Nyon families when they want to have fun without a hassle. People come here to swim, splash around with little ones, and provide children with a safe aquatic playground. The atmosphere is simple and family-friendly, with areas for swimmers and others for beginners.

What your children will discover

The youngest love to stand in the water and play in the warm water, enjoying gentle slides and splashes that make them laugh. Confident children gain self-assurance by swimming a few laps, going under the water tunnel, or trying out the breaststroke. The water stimulates motor skills, balance, and breathing. It’s also a good environment to learn to follow instructions and share space with others.

Before you go

• From what age? From 6 to 12 months with a parent in the water, very good from 2–3 years to explore, and perfect up to 10–12 years to progress. Teens also find it enjoyable with the swimming lanes.
• How much time to plan? Between 1 hour and 2 hours is ideal. Little ones tire quickly, so it's better to save energy for the outing and snack.
• Calm, educational, or sporty? A bit of all three. You can play, learn to float, and then finish with a few laps.
• Do you need to book? Not for open swimming. Classes (baby swimming, learning, aquagym) need to be booked in advance.
• Is there an entrance fee? Yes, it’s a municipal pool with rates for children, adults, families, and subscriptions. Remember to bring a card if you go often.
• Stroller and public transport? Urban buses TPN serve the Cossy area from Nyon station in a few minutes. Stroller access is possible up to the changing rooms.
• Accessibility? Facilities for people with reduced mobility are generally provided in this type of facility. Don’t hesitate to check the specific arrangements before your visit.
• What to bring? Swimsuits, towels, goggles, armbands for the little ones, non-slip sandals, water bottle. A coin (often CHF 1 or 2) may be useful for lockers. A swim cap is not always mandatory, but tied hair and a soapy shower are recommended.
• Safety? Lifeguards on site, shallow areas, and depth indicators. Children remain under the active supervision of an adult.
• What season? All year round. Perfect when it rains, is cold, or when looking for an active yet gentle activity.
