Did you know that the Wadden Islands are not the only place in the Netherlands where you can go mudflat walking? The Sophia Polder is a relatively new nature reserve near Dordrecht in South Holland. At low tide the polder is dry and is perfect for rugged mudflat hiking trips.
Sophia Island has 77 hectares of land and floods regularly because of the low dikes.
Sophia Polder guided hiking trips
Mudflat walking is only allowed with a forester. Nature conservation organisation Zuid-Hollands Landschap offers guided mudwalking excursions for adults and kids from 9 years old.
Visit Sophia Polder on your own
Nobody lives here and the island in the middle of the busy tidal river Noord can only be reached by pedestrian ferry. Walk across ramps and paths and experience the isolated island feeling.
The viewpoint on the south side of the island offers a beautiful view of the riverfront of the historic city of Dordrecht. From the east side of the island you can see many ships pass by enroute to Rotterdam or Antwerp.
Bird watchers’ paradise
The freshwater tidal flats are full of birds. Bird lovers can spot around 25 bird species including Canadian geese, seagulls and wadering birds like spoonbills, godwits, avocets and redshanks. From the birdwatching hut in the middle of the island you can see the incoming and outgoing water.
The free ferry to Sophia Island can take up to 11 passengers and leaves from Veersedijk 301 in Hendrik-Ido-Ambacht. The crossing takes 5 to 10 minutes. The ferry does not sail in case of dense fog or thunderstorms. The ferry is operated by volunteer skippers.
