Despite the exciting leap to the ATP Challenger Tour, the heart and soul of the Open de Sion remain completely unchanged. This tournament has always been built around three core values: community, passion, and proximity — and that commitment is stronger than ever for the 2026 edition.
-
Free Public Access for Everyone: Upgrading the tournament status hasn't meant putting up paywalls. Experiencing high-caliber ATP tennis up close remains completely free of charge for spectators all week long, ensuring sports fans, families, and newcomers alike can enjoy world-class competition without barrier.
-
An Intimate, Front-Row Atmosphere: Unlike massive, distant stadium arenas, the unique layout at TC Valère brings you right to the edge of the action. Sitting just metres from the court lines, you will hear the pop of the ball off the strings, feel the raw power of every serve, and see every grain of red clay kick up as players slide into their baseline recovery shots.

A Vibrant Summer Festival Grounds: The experience extends far beyond the final point on court. With fantastic food and regional wines served right at the club and special side events, the grounds of TC Valère serve as the ultimate social and sporting gathering spot in Sion this August.
