Heligoland Felswatt, Mudflat in Heligoland, Germany
Heligoland Felswatt is a rocky and sedimentary seabed along the North Sea coast that becomes walkable when the tide retreats. The exposed zone supports specialized marine life adapted to both underwater submersion and air exposure.
The area became protected under German administration after the island returned to Germany in the 1950s. This rocky and muddy seabed has been shaped by tidal forces over thousands of years.
The exposed mudflat shows how the rhythm of tides shapes life on this island. Local guides often point out how residents have learned to work around the water's constant movement.
You can only visit during low tide periods, so check tide tables before going and wear proper footwear. The surface can be slippery and muddy, making sturdy shoes and caution essential for a safe walk.
Parts of the seabed preserve fossil traces from ancient marine life, revealing millions of years of geological history. These imprints can sometimes be spotted by careful observers exploring the exposed surface.
