Taste the iodine adventures of the fort of bertheaume!

► The air of the sea, the taste of adventure!
On an exceptional natural site, Bertheaume Iroise Aventure offers you a unique activity in Brittany.
With family or friends, come and discover the iodised paths of the Bertheaume fort island:
♦ rock courses with continuous lifeline (maximum safety), evolving adapted to all levels of difficulty
♦ cable bridges
♦ climbing
♦ caving ladder and zip lines over the Iroise Sea (one of which is 200 metres long and nearly 40 metres high!).

We sometimes have to postpone or cancel some departures depending on the weather conditions: wind direction and strength, tidal range and wave height.
For all these reasons, it is imperative to book on 07 84 46 36 44.
