The Wadden Sea is a shallow body of water with tidal flats and wetlands, rich in biological diversity

The area is typified by extensive tidal mud flats, deeper tidal creeks and the transitional zones between the sea, the freshwater environment and the surrounding (is)lands. Its coastal wetlands are considered one of the most important areas for migratory birds in the world, with an average of 10-12 million passing through it each year. 

Community Perspective: the site comprises 7 components and different national parks (the bigger islands mostly aren’t included). Reviews are available for places in the Netherlands (John, Clyde, Chris, Els), Germany (John, Ian, Michael, Nan) and Denmark (John). The ‘proper’ way of exploring the Wadden is via a mud hike like the ones Kbecq, Assif and Nan reported on.

Wadden Sea by Nan

The Wadden Sea is probably the first WHS I visited (disregarding its inscription year). My grandfather was from Sylt, Germany's northernmost island, part of the North Frisian Islands and surrounded by the Wattenmeer Nationalpark. We would go once a year to visit relatives of my father's when I was little. When we crossed the Hindenburg Damm to get onto the island we were crossing right through the national park.

Growing up in Schleswig Holstein meant that the Wadden Sea featured prominently in any vacation or weekend excursion plans. Be it a daytrip to the beach in St. Peter-Ording, the nicest mainland beach in Schleswig Holstein, a cruise to Helgoland from Büsum, or spending repeated summer vacations as an adolescence in the Fünf Städte Heim in Hörnum, Sylt.

What makes the Wadden Sea so interesting is that there are few places in the world where you will experience the magnitude of the tides so directly. Paths between islands and to the mainland open up twice a day and get swallowed up a few hours later, rivers (Prils) appear and disappear. And the wildlife, most notably birds, capture the mudflats.

In addition, the Wadden Sea faces the rough North Sea with high dikes lining the shore lines and land won and lost over millennia. While not part of the site, the Frisian Houses, the Halligs, ... all the ways the locals adapted to the dangerous North Sea and transformed the landscape, are amazing to see. Personally, I feel this should be a mixed site and encompass the traditional Frisian houses, the man made islands and the dikes.

Mudflat Hiking

The proper way to experience the Wadden Sea (and a prerequisite for counting this as visited @Ian), is to join a Wattwanderung (mudflat hike). I would recommend doing a crossing between islands or from the mainland to an island for the best experience. You will feel like Noah and his tribe fleeing Egypt. Several options exist. I had the privilege of taking the late Iain Jackson (pictured) on a hike from Dagebüll to Oland, a Hallig. You can also walk from Cuxhaven to Neuwerk. Or between Föhr and Amrum. More options exist in Denmark, the Netherlands or the East Frisian Islands.

While these walks may seem trivial and joining a tours can be boring, especially if you don't speak the language, you should still join a tour. In the Netherlands and between Amrum and Föhr tours are required. Walking out into where a few hours later water will be is dangerous. The path may not always be straight and you may have to circumvent Prils, i.e. rivers, that have strong currents and cannot be passed. And what is passable now, may not be passable in an hour. Last but not least, you will need a return ride and tour guides organise this.

Where To Go?

The area is pretty large. Of all the inscribed areas, I have seen the Wadden Sea in Denmark (Rømø, Fanö), in Schleswig Holstein (Sylt, Amrum, Föhr, Oland, Husum, ...) and as last addition Terschelling in the Netherlands. I am still missing Neuwerk (part of Hamburg state) and the East Frisian Islands of Lower Saxony.

Of the many options, I would probably recommend Sylt for a first time visitor. On the eastern side of the island you have the mudflats, on the west coast the rough North sea. And in Keitum you have a tradition Frisian village. It's a 3.5h train ride from Hamburg and has plenty of tourist infrastructure (hotels and restaurants). It's not a cheap destination though if you come in season and stay overnight.

Generally, I found the North Frisian Islands more interesting than the West and East Frisian Islands. Sylt and Amrum are very much like the West and Frisian Islands (sand islands), but the islands not directly facing the North Sea (e.g. Föhr, the Halligs) are distinct as they are grass islands, many man made.

Personally, I still want to hike from Cuxhaven to Neuwerk. And sleep on a Hallig, a man made island that gets submerged during floods, with only the farm houses above water as they are build on hills.

Last but not least, in Germany (and I would presume this holds true for Denmark and the Netherlands) to enter the core zone you have to hike out into the Wadden Sea. The first 50m off the Wadden Sea are not part of the national park and thereby not in the core zone. The reason is that flood control trumps preservation.

I think that in order to appreciate the Wadden Sea you have to go on a mudflat hike. Living in Hamburg, I have been to several ones, and I always find this weird ecosystem fascinating. Coming from Hamburg you can reach the Northern Sea at Dünen/Cuxhaven in Lower Saxony or at Friedrichskoog/Büsum/Sankt Peter in Schleswig Holstein. I have been to mudflat hikes at all these points and, surprisingly enough, the landscape and the nature of the hike differ considerably. One of the reasons is a feature of the Wadden Sea called tidal creeks (Priele in German). These are streams which appear during low water and can be very strong. Their route remains steady. If you go hiking next to such a tidal creek you cannot normally cross it. This affects the distance you can reach from the beach. This is why a mudflat walk from Büsum, for example, cannot take you to the deep sea. The terrain is also different, with mud of various degrees of density. Finally, in some hikes you can reach areas in which you can observe seals. I personally preferred Cuxhaven as a point of departure. Hikes can take from 1 hour up to 6 hours. Make sure to either join a tour or take the necessary precautions as mudflat hikes can be dangerous.

Wadden Sea by Kbecq

A couple of years ago we visited the German part of the Wadden Sea WHS with stops in Dorum (where you can have a look inside the Obereversand lighthouse) and Dornum (where you can make a walk along the Wadden Sea following the Heller path).

However, to get a proper feel of this WHS we decided to participate in a ‘wadloop’ (mud hike) in the Dutch part of the Wadden Sea WHS. There are various agencies offering such hikes using different routes. We opted for the one starting from the little village of Wierum to the Engelsmanplaat (Englishman sandbank) and back to Wierum.

In total it’s about 12 km which takes about 4 hours, a short break on the sandbank included. A guide is recommended (or even obligatory?) since the sea currents can be very dangerous.

The hike itself is quite exhausting as you are walking in the mud all the time and for a fair amount of time also knee/waist deep through the water. Nevertheless it’s a special sensation and in the future we might also try out other routes.

I spent some time exploring the German part of this WHS, particularly around the coastal town of Norden, which has good access to mudflats which you can go out and see for yourself.

There are the mudflats, of course, for those who want to see the importance of the region close up. For birdwatchers, the area around Norden and the Wadden Sea more generally provide viewpoints to see the millions of migrating birds that stop here to rest during their journeys.

The popular ‘Seehund Station’ is a centre near the coastline of Norden that rescues and looks after injured or orphaned seals. Experts nurse them back to health and then release them back into the sea when they are strong enough to look after themselves.

Although there is human development along the coastline, the most important areas of natural significance have been well protected for everyone to enjoy.

With the expansion of this WHS to unclude the area within the borders of Denmark, I decided to include a visit to this area whilst in the Kingdom.

Basing myself in the port city of Esbjerg I made journeys out to the off-shore islands of Romo and Fano.

To reach Romo I took a train to Skaerbaek,then a bus from there across a causeway to the island, and then to the southern end at Havneby. From here and from the causeway a variety of marine bird life could be seen.

Fano was reached by ferry from Esbjerg. A bus ran the length of the island from Nordby to Sonderho. Sonderho contained a number of examples of traditional domestic architecture, as well as bird life in the salt marshes. At Nordby I encountered the only mammals I saw; a family of seals basking on a sandbank.

Wadden Sea by Els Slots

The Wadden Sea WHS covers a huge area along the coasts of the Netherlands, Germany and Denmark, so it’s an easy site to tick off. Getting a real feel for it though is a whole different story. I believe one should at least try to cover several different areas and take in both the marine and coastal aspects. In early August 2015 I made my third trip to the inscribed area, still searching for its soul.

My first visit was in 1982: I was 12 years old and went on a school trip to the Wadden island of Vlieland. It was the first time that I went away for a couple of days without my parents, not counting a disastrous girl scout camp that I left crying already after one night. Vlieland was more of a success, it’s a really popular holiday island geared to an active vacation. I still have some very funny pictures of that time. Although the islands are outside of the core zone of the WHS, you’ll inevitably cross the Wadden Sea by ferry. So technically – I had been there.

In 2011, on my way to the T-listed Eise Eisinga Planetarium in Franeker, I had driven the Afsluitdijk route. The Afsluitdijk is a major causeway damming off the former Zuiderzee and turning it into the freshwater lake of the IJsselmeer. It has been a candidate on its own for the Dutch Tentative List, but it was rejected because it isn’t a national monument and its universal value was seen as doubtful. Halfway there’s a parking lot with a footbridge, from where you can see the IJsselmeer on one side and the Wadden Sea on the other. It’s a windy spot, and on the north side, you taste the sea salt on your lips.

This weekend I decided to check out the coastal stretch between Den Oever and Den Helder, at the tip of the province of North Holland. First I drove to an area named “Balgzand”. This is the best place to see lots of birds: at low tide, large numbers of them congregate at the sandbars to search for little creatures to eat. The zone itself is not accessible, you have to watch from one of the bird hides. A group of some 40 spoonbills was feeding and washing when I arrived. You’ll need a strong lens to take good photos, as the hides are far away from where the action is.

I then drove on to Den Oever. This is a small fishing village where not much seems to happen. I parked in the streets and then climbed the seawall that guards the town. Here a combined biking and hiking path gets you closer to the sea, though the tide was still low and there wasn’t much water in sight. I had a pleasant walk along the coast to the Wadden Harbour of Den Oever, a fishing harbour where sometimes seals are seen. I did not see anything but birds, however, mostly cormorants drying their feathers in the sun.

So that makes 3 visits in total, but I am still not satisfied with the “experience”. It’s really hard to say which part of the designated areas delivers a representative visit for the casual visitor. The official website is not much help as it is more about tourist promotion of the general area than about the WHS. Maybe a proper mud hiking tour (only possible with a guide) would do the trick to at least get a "feel".

The Wadden Sea WHS area is large. One part in the North of the Netherlands especially around the Lauwersmeer above is the area of my roots. I visited it mid June 2015. I went for a tour on the Waddenzee on boat, bad weather so only tour. We did some walking on the mud flats, but it was high tide so we could not walk far. And we eat gurnard fish from the Waddenzee, durable fish! It's a great area and for this i ticked of the Dutch part, the Islands are not really part of it. Ah, we saw some seals too of course. Check my site for some photos.

I visited this WHS in May 2012. I visited the Netherlands side of the Wadden Sea around the Frisian islands. The highlight of my visit was exploring the Wadden Sea coast of Texel by boat, spotting seals and a huge variety of birds on the way.

Wadden Sea by Ian Cade

“I’m going to visit some mudflats!”

“Why?” my colleagues asked, as they seem to delight in eking out the weirder destinations that visiting World Heritage Sites takes me. Therefore they had great fun when I unveiled my plans for New Years day 2011.

“They are a World Heritage Site”


“erm...[googling]...they seem to be home to 6.1 million migratory birds”

“Wow, will you get to see them”

“erm, probably not, I don’t think mid winter is the main time for them.”

“OK, so which part of the National Park are you going to visit”

“I found a Lighthouse opposite the container port”

“Doesn’t sound to Natural why are you heading there?”

“It looks walkable from the ferry port at near Bremerhaven”

“Walkable, how far?”

“About 12km round trip, probably in the snow I guess”

“Wow you must really like birds”

“No, not really I don’t have much interest in them”


“I told you it is a World Heritage Site right?”

And so that is how I planned my day and that is how it turned out. To walk off the excesses of the festive period I took a stroll to Langlütjen I on New Year's Day 2011.

To my surprise there were a few birds flying around near the sea, I saw some Geese (Barnacle?) Ducks (Eiders?) and something that I think may have been a Curlew, but as I said, birds really are not a speciality of mine.

I actually enjoyed my walk through the flooded grass lands and walking out on the manmade peninsular gave me a great view of the birdlife around me as I could walk beyond the shoe line even with the tide higher. One thing that surprised me was that the sea was frozen when I finally got to it. I had never seen the sea like this before so that was quite rewarding. It also meant that the few birds that were around clustered in small ponds of water that had remained unfrozen, making them easier to spot.

I won't pretend that I have seen the best of the Wadden Sea, but then again it was never a site that was going to really appeal to me. It was however another example of how hunting out World Heritage Sites can take me well of the path I would normally choose, and that was the most rewarding this about it. Oh yeah and it kept my colleagues entertained on my return to the office over a few tasty Bremer Kluten, now I just have to work out which site to trek to next.

Wadden Sea by John Booth

This site covers almost 10,000 square kilometers, and stretches for 400km along the north coast of Europe from the Netherlands to the Danish border. To get an appreciation of this site I visited it at several diverse locations in the Netherlands and Germany:

Texel Island - reached by ferry from Den Helder, then by bus to Oudeschild, a small port facing the Wadden Sea. From here there are excursions by boat to see the wildlife on the sandbanks.

Terschelling Island - reached by ferry from Harlingen. From the port on the island I walked to Green Beach to see the bird life there, but saw more from the deck of the slow ferry on the way back to Harlingen.

Norddeich - from here there are ferries to Norderney and Juist Islands. I took an informative cruise to the National Park to see the seals and birds on the sandbanks adjacent both islands.

Wilhelmshaven - saw views over Jade Harbour from the Wattenmeerhaus, a museum of the fauna and flora of the Wadden Sea at South Beach.

Cuxhaven - I just timed it correctly to catch low tide at Dunen Beach in order to take a trip by horse and cart out onto the sandbanks. I also visited the National Park exhibition at Sahlenburg Beach.

Sylt Island - This island is accessible only by train or boat. I took the train to Westerland, then a bus to Hornum on the southern tip of the island. Then I took a boat cruise via the Halligen to Husum, back on the mainland.
