Island tradition continues in the making of Læsø salt. At one time an island export, the salt is now sold in small souvenir bags and is respected for its medicinal qualities as well as its gourmet potential. On the island you can visit the saltworks, and take a salt bath at Læsø Kur, a beautifully designed wellness centre inside a former church in Vesterø Havn, a short walk from the ferry port.

The island has a few small towns (Vesterø Havn, Byrum and Østerby Havn), a couple of medieval churches, and a smattering of museums (including a seaweed-roofed farm museum).

South of the main island is Rønnerne, an area of tidal wetlands with extensive seaside meadows and heathland, impressive birdlife and unique flora and fauna.
