Authie Bay

At the mouth of the Authie lies a bay lined with dunes. It is here that the "great dune" rises, shaped by the whims of the wind. This mountain of sand moves and gradually consumes the woodland that lie behind it. This movement, though slowed by the sea grass, will one day conquer it. Further down the estuary lives a colony of harbour seals. Every day, these seals rest on the sandbanks uncovered by the sea at low tide.

Opening hours: all year round
