Læsø is the largest of the islands in the Kattegat Strait. It is famous for its unique nature and the salt works museum. There are also sandy beaches here, and in summer the weather is dry, which is perfect for relaxing by the water.
In the Middle Ages, the most important activity of the inhabitants of Læsø was salt-making. Today, this method of obtaining valuable raw material is no longer continued. There are only shows for the needs of tourists conducted, among others in the open-air museum of the Salt Works in Læsø.
The largest town on Læsø is Byrum, where you can see a Gothic church and some historic houses. On the other hand, there is a large seafood processing plant in Osterby. There are quite a few old half-timbered houses with seaweed roofs preserved on the island. One of them is the House of Hedvig, which is open to the public. The traditional building also houses the Læsø Museum with exhibitions on the island's life since the Middle Ages.
Læsø is a wildlife refuge. There are the largest salt marshes in Denmark overgrown with halophilous vegetation. There are also swamps, vast meadows, and sandy beaches such as Danzigmann Beach. There are small harbors in the settlements, such as the Ostby Harbor, where sailing boats and yachts can dock.
