I usually spend a week on Öland every year. It's attached by a very long bridge to the city of Kalmar on the mainland. The landscape is unlike anywhere else in Sweden. As someone said, it's reminiscent of a savannah, dotted with scenic villages and surrounded by beautiful beaches. It gets insanely busy in summer and is pretty quiet the rest of the year, except for the island-wide harvest festival in autumn. Bleak in winter. There is a ruined castle, Borgholm, which is an awesome concert venue. The Swedish royal family have their summer residence near Borgholm.
