The idyllic island Kråmö lies a comfortable boat trip from Trosa. Twelve cottages of various sizes are available for rent on the island. They do not have electricity or running water. The harbour is very idyllic and a wonderful place for swimming. Sauna bathing, fishing and berrypicking can be done. There is also a big grass area and barbecue places.
Kråmö island, with the old island farm which has roots in the 1600s, was formerly part of the estate Tureholm. In the 1940s, Kråmö was bought of a dairy owner who built the cottages for their workers. Nowadays this summer idyll is owned by Trosa municipality. There is a café that sells ice-cream and simpler foods at the pier.
There are countless stories about the legendary Tärken who lived on Kråmö for 52 years. Einar Tärk and his wife Hilja were the last residents of the island, but in 2003 they moved to Trosa. Several generations of children in Trosa remember Hilja who worked in the school canteen. Einar, who fled Estonia in a rowboat in the 1940s built solid fishing boats at Kråmö. The biggest boat he built is still there. Nowadays there is a museum on Kråmö. It shows, apart from archipelago subjects, a part of Tärkens life work. Tärk has also given its name to the treacherous stone collection north of Kråmö between Brännskär and Högholmen. For a long time it was not marked on the chart. It is said that Tärken stood on his mountain and looked for boats that hit the stones. When someone got caught, he went out with the fishing boat and pulled off the boat – against fair compensation of course. Not until he himself got stuck there and a neighbor had to come and pull him off for a fee, of course, came “Tärks grund” to be marked on the chart.
