Experience the magnificent nature in Wadden Sea National Park
Experience marsh landscapes, tidal flats, vast horizons – in short, unique nature that you can only find at the Wadden Sea.
Denmark's unique tidal area
The Wadden Sea National Park, a UNESCO World Heritage Site, stretches along the southwestern coast of Denmark and is known for its dynamic landscapes, shaped by the tides. Here, sea and land meet in an ever-changing dance, where sandbanks, mudflats and marshlands create a unique ecosystem.
The area is home to a rich birdlife and serves as one of the world's most important resting places for migratory birds. The Wadden Sea National Park offers unforgettable nature experiences - from hiking in the marshes to seal safaris and black sun. An experience of Denmark's wild and vibrant nature!

FAQ - Frequently asked questions
Here are a few of the typical questions we get. You can read much more about the trip and the preparations on the page worth knowingIf you have any other questions, you are always welcome to contact us at contact@fremadmarch.dk.
The route
The routes go through the scenic surroundings of the Wadden Sea National Park. The routes are planned with beauty, experiences, challenges and attractions in mind. If you are not already in love with the national park, you will certainly be on your route.
The routes will be marked with wire flags, so you can safely enjoy your route without having to look down at a phone all the time to find your way.
However, as an extra precaution, we recommend that you have downloaded the selected route to the Komoot app. Before starting, you will receive the route in GPS form, after which the app will show you the way with your phone, just like you know it from car navigation. Your mobile phone or GPS device will guide you through even the darkest forests without any problems.
Which distance should I choose?
With the right training, anything is possible. Longer trips are a lot about mindset and belief in your own abilities. Prepare yourself, spend time on training trips, get out into nature and feel what it can give you. Because it can give you a lot.
The training rides also help you gain experience in choosing shoes, socks, and what food your body works best with. As the difficulty and length of your training rides increase, your body also adapts to the distances and increased endurance demands.
Take note and choose a distance that suits you and your level of ambition.
Depots along the way
We have placed the depots so that there will be opportunities to use the toilet and refill water at all of them. In addition, there will be soda, coffee, fruit, energy and chocolate bars, mini salami, sweets, rye bread, toast with Nutella and much more.
Equipment – what should I bring?
Required equipment: backpack, mobile phone, power bank, headlamp, water bottle/camel bag, overshirt.
In addition, it may be a good idea to bring an extra pair of socks as well as food and snacks.
Food – what should I bring?
It may be wise to bring some rye bread snacks or buns. Although there are depots along the way, you should be aware that the march is a self-catering event. Test what works for you on your training trips and make a meal plan for yourself. It may help you to eat a rye bread snack every 2 hours. On the long marches you will feel hungry, and so it is important to force yourself to eat to give your body some energy to work with. Otherwise, your body may go cold.
What do I do if I get injured along the way or can't continue?
If you are forced to abandon the hike, there are several places where you can shorten your trip and return to the start/finish line or head towards the nearest depot.
When will I receive information about the event?
Shortly after your registration, you will receive an order confirmation with a QR code. This code must be presented before starting in the starting area.
You will receive ongoing emails about the event, and in the weeks leading up to the event you will receive a link to the route you have registered for.
