Discover Denmark’s largest area of marshland, Tøndermarsken.

The 54-kilometre Marsh Trail and eight shorter hiking trails take you to see every corner of Tøndermarsken.


Distance: 54 km

The fifty-four kilometres of hiking trail bring you closer to this very special landscape. At first glance, the natural environment here seems bleak and untamed but it was designed meticulously – formed by the lives of local people who worked with and against the water.

When you walk the Marsh Trail, you feel the wind on your face and observe a flat landscape with dykes and birds as far as the eye can see.

The trail takes you to everything from dykes and pumping stations to extensive marshlands, canals and lakes with outstanding natural environments and bird life.

On the marsh’s perimeter, you walk through a number of unique small towns. Tønder, Møgeltønder and Højer are located on The Geest. Rudbøl and Nørremølle are the only towns in Denmark built on dykes.

Distance: 2.7 – 12 km

There are eight shorter hiking trails associated with the Marsh Trail.

All the shorter hiking trails are circular routes, which start and finish at the same place. It is a good idea to start your hike in one of three towns – Tønder, Højer or Rudbøl – because each of the shorter hiking trails goes through one of these towns.

Each of the shorter hiking trails is colour-coded: green, blue, red or black, according to its length.

The green trails are shortest, black longest.

The shorter hiking trails are described below.
