Gränna and Visingsö are unmissable destinations offering enchanting views, manor houses, cobbled roads, bicycle rides, idyllic wooden cabins, castle ruins, paths, and oak forests. Gränna, founded by Count Per Brahe the Younger in 1652, boasts the Grenna Museum, where you can delve into the fascinating history of S.A. Andrée's adventurous balloon voyage over the North Pole in 1897. Be sure to try the town's sweet signature, the peppermint rock, originally red and white, now available in an array of flavours.

Explore the island on foot, embark on a special horse-drawn carriage (known as a remmalag), or enjoy a leisurely bicycle ride, all while taking in the picturesque surroundings.
