Golf Club de Sion sits in the Rhône Valley near the historic town of Sion in the canton of Valais, surrounded by the dramatic Alpine landscape of southern Switzerland. The course was designed by a member of the Harradine family, likely Donald Harradine or one of his sons, who were prolific golf architects in Switzerland and across continental Europe throughout much of the twentieth century. The Harradines designed or redesigned dozens of Swiss courses, adapting their layouts to the country's varied terrain and often working within constrained valley and hillside sites. The routing at Sion takes advantage of the valley floor setting, with the surrounding peaks providing a striking backdrop to play. Courses in this region typically feature relatively flat or gently rolling terrain compared to mountain layouts at higher elevations, though strategic bunkering and water features often define the challenge. The Rhône Valley's climate allows for a longer playing season than courses at higher altitudes, and the area's viticultural tradition and proximity to Sion's medieval castles and old town contribute to the regional character. Golf Club de Sion serves both local members and visitors exploring the Valais region. Like many Swiss clubs established in the mid-twentieth century, it reflects the growth of golf in Switzerland as both a recreational pursuit and a draw for tourism in areas known for skiing and mountain scenery.
