Why the tide matters on every mudflat walk
After low tide the water rises again. Small channels and tidal creeks on the flats can fill with the flood. On top of that, visibility and conditions can change quickly when the weather turns or sea fog rolls in.
So it is not enough to look up the time of low tide. Distance, starting point, the way back, weather, water level and the local guide all belong together.
Check the tides, agree the route on site
Check high and low tide for the right place or reference gauge. Agree on the exact route and return time with the guided tour or the local national park information. Conditions and rules differ by area and tour.
The tide map helps you understand the tide at the selected place or its reference gauge. It does not calculate a walking route, whether a path is passable or a safe return time. Do not use it as permission to go out onto the flats on your own.
Never underestimate tidal creeks
The Wadden Sea National Park warns against crossing tidal creeks: small, inconspicuous channels can fill with the flood and turn into strong currents. Follow the instructions of your mudflat guide and any closures on site.
Do not go onto the flats when thunderstorms are possible or an official severe weather warning is active. Sea fog can reduce visibility within minutes. If the weather or your orientation gets worse, follow the guide’s emergency plan and the instructions on site.
A quick check before you start
Never go onto the mudflats alone, and never go far out without a certified mudflat guide. Agree on the route and return time with the guide beforehand. Have you checked the current weather and area notices? On a guided tour, follow the guide’s equipment advice and instructions.
Use tide times as a starting point for talking to a local mudflat guide. A gauge reading alone cannot judge whether a route is safe or passable.

Is the time of low tide enough to plan a mudflat walk?
No. Route, start and return time, weather and local conditions must be considered together. Ask a local mudflat guide or the national park information.
Can I cross a tidal creek at low tide?
Don’t rely on it. The Wadden Sea National Park warns against crossing creeks because they fill with the flood and can develop strong currents.
Can the tide map approve a route?
No. It shows tide values at a gauge. It does not calculate mudflat paths, whether creeks are passable or safe tour times.
