Kökar is a wonderful island with the characteristic barren landscape of the outer archipelago. The ruins of a Franciscan monastery from the 15th century, the Bronze Age settlement of Otterböte and the local museum in Hellsö are worth seeing. The island of Källskär with the Ice Age formation "Källskärskannan" also shows the remains of an eccentric Swedish nobleman. It can be reached by boat and the island is also ideal for cycling.
