Domaine des Îles in Sion: a day of nature and leisure with family

A green interlude in the heart of Valais

South of Sion, the Domaine des Îles is a large relaxation park around a lake, easily accessible and designed for families. The atmosphere is simple and friendly: flat paths, shaded lawns, a beach, playgrounds, and gentle activities at the pace of children. One can easily spend half a day there... and often extend it.

What your children will love

Here, you choose your pace. The youngest explore the playgrounds, build sandcastles, and watch the ducks. The older ones alternate swimming, scootering, or biking around the lake. In summer, you can rent light equipment (such as paddles, pedal boats depending on the available providers) and extend the fun on the water. The paths are wide and smooth, perfect for balance bikes and strollers.

A simple, active, and serene day

The activity is mainly outdoors, between nature and leisure. Plan for 2 to 4 hours depending on your schedule, but the whole day goes by quickly with swimming, games, and picnics. Access to the site is free; only certain activities offered by providers are paid (paddle, pedal boats, adventure course nearby, mini-golf depending on the season). Swimming takes place in designated areas; supervision varies by season, so it's best to keep a close eye on the children.

It is suitable from age 2 to enjoy the games and the walk; teenagers also find their share with water activities and informal areas to expend energy. In terms of development, several boxes are checked: motor skills (walking, biking, games), confidence (in the water, with a vest if needed), socialization (meetings in the park), curiosity (lake fauna, seasons), and sense of autonomy.

Before you go

• Reservation: unnecessary for park access. Some paid activities may require a reservation during peak season.
• Budget: entry is free. Bring some cash/card for rentals, ice creams, or coffee at the kiosk/restaurant.
• Access: parking on site; buses connect Sion train station to the stop "Les Îles" (short final walk). The paths are stroller-friendly.
• Equipment: swimsuits, towels, hats, sunscreen, water bottles, picnic. For mid-season, bring a light windbreaker and spare clothes.
• Safety: armbands/vest for little ones, water shoes if sensitive to pebbles, and reminder of rules near the water.
• Best season: from spring to autumn. Summer for swimming, spring and autumn for cool walks.

Parent tips

• Arrive early on summer weekends to settle in the shade near the water.
• Set up a simple base: blanket, snacks, swimsuits already on to save time.
• Walk around the lake at the beginning of the outing when everyone has energy.
• Bring light games: ball, frisbee, bucket/shovel.
• Keep a dry change in the car for the return.
