It’s ideally located by the Sciez-sur-Léman marina, about a five-minute walk from Camping du Châtelet. With a friendly, accessible setup and a full season of activity, it’s a natural home base for both first-timers and seasoned sailors.

Close by, Sciez Beach—also less than a five-minute walk—adds comfort to your session days. In summer (July and August), swimming is supervised and lake water typically ranges around 20–24°C, making post-session dips especially inviting.

For additional rentals and course formats, Aqua Léman Nautique offers pedal boats, windsurfers, canoes-kayaks, SUPs, and motorboats, with options from 5-day courses to half-hour rentals.
