The park was created through the gravel extraction processes used to build infrastructure in the Rhone Valley.
The central lake is specifically designed with a shallow beach area for children.
The site operates as part of a larger ecological corridor along the Rhone, providing habitats for local waterfowl.
The name 'Domaine des Iles' refers to the historical 'islands' created by the braided nature of the Rhone River before its canalization.
Domaine des Iles is a recreational park situated on the banks of the Rhone River in Sion, centered around two artificial lakes. The site features a range of family-oriented facilities including rental cabins, a swimming lake, and designated picnic areas. It serves as a primary hub for outdoor activities in the Valais region, offering facilities for beach volleyball, football, and miniature golf. The park is managed by the Bourgeoisie de Sion and provides a controlled environment for swimming with seasonal water quality monitoring. Visitors can access gravel paths surrounding the water bodies for walking and cycling. The facility also includes integrated dining options and barbecue stations for public use. It functions as a multipurpose leisure zone connecting local natural landscapes with structured recreational amenities.

Bring your own charcoal if you plan to use the public barbecue stations, as they are not always stocked.
Check the official Bourgeoisie de Sion website for real-time water quality status during peak summer heatwaves.
The western end of the lake is generally quieter than the areas immediately surrounding the restaurant and rental cabins.
Do not attempt to swim in the non-designated areas of the river or the secondary fishing lake, as currents and water depths vary significantly.
Water-based facilities and rental cabin services operate primarily from late spring through early autumn; the park grounds remain accessible year-round for walking.
Dogs must be kept on a leash at all times; designated swimming areas are for humans only.
