Go on a safari tour at Eriksberg's Wildlife Park and see wild animals in their natural habitat. Red deer, fallow deer, Père David’s deer, European bison, wild boar and moufflon roam freely in this unique nature reserve in the archipelago.

The fenced portion is about 900 hectares, which means that Eriksberg is one of northern Europe's largest wildlife reserves.
