Sion sits in the Rhône valley, surrounded by vineyard terraces and, further up, the peaks that make Valais one of the country's ski heartlands. It's the last place you'd expect to find continental Europe's first dedicated surf park — and yet here it is: Alaïa Bay, a Wavegarden installation larger than a football pitch, built into a landscape that has nothing to do with the sea.
The technology is the point. Rather than depending on a river's mood, Alaïa Bay's system can push out anywhere from 300 to 1,000 waves an hour, tuned to different skill levels across the pool at once — beginners on one side, advanced riders working a steeper section on the other, all in the same session.
Powered by the mountains, not against them
What makes the park feel less out of place than it sounds is the power source: hydroelectricity, drawn from the same alpine water cycle that feeds the rivers everyone else in this journal is chasing. It's a strange kind of continuity — meltwater that would otherwise run down through Bremgarten or Thun instead spends a detour generating a wave in a valley two hours south.
What's on offer
Beyond open sessions, the park runs structured beginner classes, softer "Waikiki" sessions aimed at longer, gentler rides, and even a surfboard-building workshop for anyone who wants to leave with more than a sunburn.
Practical notes
- Water is genuinely warm — a real contrast to the glacial rivers further north, and worth planning around if cold water isn't your thing.
- Beginner lessons are available and recommended for a first visit; the wave is more consistent than anything a river offers, which makes it a good place to actually learn technique.
- Book ahead — unlike a river wave, sessions here run on a schedule.
