Winter holidays 2026

From Mandø, we walk about 2 km along the dyke and across the seabed to the seal bank, where ‘Jørgens Lo’ – a watercourse about 300 metres wide – separates us from the sandbank where the seals lie. The seal bank is one of the largest breeding grounds in the Wadden Sea National Park. Around 200 seals usually rest here. The nature guide brings binoculars so that we can get very close to the seals without disturbing their natural behaviour. The most curious seals may come very close, in the water right in front of us...

All participants must be able to walk at least 5 km without any problems.

Who stole the world's largest oyster?

Join us on an exciting expedition through our exhibition and learn more about our new resident in the Wadden Sea – the Pacific oyster.
Why is it considered invasive? Who eats oysters? Where does it come from? And how big is the world's largest oyster?

The tour lasts approximately 45 minutes. Afterwards, you can follow the trail in the exhibition and around our grounds to find out who stole the world's largest oyster.

The tour is in Danish only.

On Tuesday, 10 February, and Thursday, 12 February, between 1 p.m. and 3 p.m., we will be baking delicious pancakes over the fire at the Wadden Sea Centre. Come along, enjoy the cosy atmosphere and warm yourself by the fire.

Join us on Thursday, 12 February, between 11:30 a.m. and 12:00 p.m., when our aquarium fish are fed, and ask our nature guide anything you want to know about fish.
