Cross the Bay Exclusively with a Certified Guide

Traversing the expansive mudflats of the bay on foot is an unforgettable wilderness experience, but venturing out alone is dangerously deceptive. The tide rushes in at tremendous speeds—often described locally as rivaling a galloping horse—and hidden pockets of wet sinking sand (known as mollières) can trap unsuspecting hikers within minutes.

Always book an outing with an accredited nature guide (guide nature breveté). These local experts read the shifting sandbanks, navigate tidal channels safely, and equip you with essential knowledge regarding tide tables and maritime weather shifts. Ensure you dress appropriately in bare feet or old neoprene booties during warm months, or sturdy tall rubber boots in colder seasons.
