Furholmen has a long history. The most heard about is the bathing story.

In the early 1920s, it is documented that Furholmen in Strömstad was an organized sea bath.
It had been discovered that it was not dangerous to swim in the sea. And above all not without a doctor's supervision.

The Koster Sea with all its mystery and species richness. The nature and the archipelago which is absolutely fantastic.
Visit both Sydkoster and Ursholmen, Sweden's westernmost inhabited lighthouse.
You can hop on at Ekenäsbrygga and follow us to Ursholmen and be guided by lighthouse keeper Axel Haglund.

Come in the Koster waltz....
A song written by Göran Svenning & David Hellström in Strömstad

What do you think of when you hear Strömstad?
Shrimp, salty baths or trade? Strömstad is so much more.

Is a perfect tour when you have guests you want to show the archipelago
or if the family wants a joint activity such as a break from bathing.
