The island of Öland is Sweden's second largest and features both abundant natural beauty and lots of points of historical and cultural interest. Situated just across the strait from the province of Kalmar, the island is a thin strip of land composed of dunes, low hills, beaches and forests. The southern part of the island is composed of ultra fertile limestone fields and has been inhabited since the stone age. As such, it was inscribed into the register of UNESCO World Heritage sites in 2000. The island is accessible by bridge and is open to private cars, but is also crisscrossed with bicycle trails and many visitors prefer to tour the island that way.
