We sometimes have to postpone or cancel certain departures, depending on weather conditions: wind direction and strength, tidal range and wave height.
For all these reasons, it is imperative to make a reservation by calling 07 84 46 36 44.
Two last details: the minimum height required is 1.40, and you must be 9 years old. Thank you for your understanding
