Six hours drive from Copenhagen and close to the largest lake in Sweden you find Lake Ånimmen. In this lake there is a long island called Henriksholm, on which five glass cabins are placed - each cabin close to the water and situated so no-one interfere with each other unless wanted. The cabins are made of wood and glass, without electricity and in beautiful harmony with nature. The caring owners make sure you get your three meals a day and all you have to do is relax and enjoy.
Below are images from the 72 hours at the island. More about the 72 Hour Cabins can be found here: https://visitsweden.com/72hcabin/
A few drone images... the class cabin we stayed in is in the southern part of the island and can be seen as a small white dot in some of the images.
