White Water Rafting · St Moritz
How to choose
Both tours run on the Inn River through the Engadin valley, operated by Engadin Outdoor Center, and both are open to everyone regardless of fitness level. The 120.13 CHF family rafting option covers a 3.5h session near the Swiss National Park, keeping the pace accessible for mixed groups. The 137.77 CHF Giarsun gorge run adds a full hour on the water (4.5h total) and takes you through a tighter canyon stretch where current and walls close in fast. The 17.64 CHF gap is the price of an extra hour in whitewater terrain that earns its own name. Pick the gorge run if your group wants sustained exposure to moving water and a proper adrenaline arc from start to finish.

Frequently asked questions
Which run is more intense?
The Giarsun gorge run pushes you through a confined canyon on the Inn River, where the walls amplify the current and the experience. The family rafting option follows a more open stretch and is designed to stay manageable for all ages.
Do I need rafting experience to book either tour?
No. Both tours list 'Everybody welcome' as the physical level, so zero experience is required. Your guide handles paddling instruction before you hit the water.
What is the most intense moment on the gorge run?
The Giarsun gorge section of the Inn River is where the rapids concentrate. Narrow canyon walls funnel the current and there's no easy exit, which keeps the adrenaline steady for the bulk of the 4.5h session.
How far in advance should I book?
The season runs May through September and St. Moritz draws high summer traffic from July onwards. Book at least 2 weeks ahead for July and August to secure your preferred date.
Are the tours guided in English?
Yes. Both tours are guided in English, German and Spanish by Engadin Outdoor Center.
