Mudflat walking on the Wadden Sea

The Wadden Sea, along the north coast of the Netherlands, is a UNESCO World Heritage Site of tidal mudflats. At low tide you can join a guided wadlopen (mudflat walk) across the seabed, wading through gullies to islands such as Schiermonnikoog or Ameland, a muddy, unique adventure. Seals bask on the sandbanks.

Only go with an authorised guide, as tides are dangerous; trips run from Pieterburen and other villages from May to September. Wear old clothes and high socks or trainers. The Wadden islands, such as Texel, are lovely for cycling.
