Ride the Isère on a hydrospeed board from La Plagne—an adrenaline-rich 1.5‑hour descent through boulder gardens and tight rapids. This guide explains the river, what to expect, and practical tips to prepare for the run.
More ways to explore the area's outdoor wonders
You stand on the gravel bank with the Isère roaring at your feet, cold air pinching the exposed skin where neoprene doesn't cover. Guides fit helmets and hand you a float, and the river—silver-edged, impatient—already seems to be daring you to step in. In minutes you'll trade the predictable pull of a pool for the river's shove, sliding on a hydrospeed board as rapids rock you downstream through narrow gorges and sunlit riffles.
