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 tour goes through a fascinating rocky landscape of oak woodlands, dense hornbeam woodlands and knotty conifers. There is a rich bird life as well, and one of the world’s largest stocks of the protected red water lily. The park consists of more than 925 hectares, of which 409 hectares of water. The fenced portion is about 900 hectares, which means that Eriksberg is one of northern Europe's largest wildlife reserves.

The Waikiki Aquarium, located right on the shores and run by the nearby university, attempts to recreate diverse tropical Pacific reef habitats to function as home to a number of aquatic species, including some rare fish species from the Northwestern Hawaiian Islands and the moon jellyfish.

Karlshamn's beautiful archipelago extends from the western municipal border to Sweden’s southeastern corner. This group of islands is called Hällaryd’s archipelago and consists of 270 scenic islands of different sizes with stone or rocky beaches and meadows. Joggesö, Ekö, Hallö, Östra Bokö and Fölsö are the names of some of the islands. The largest in the archipelago is Tärnö. The archipelago boats visit most islands, starting at the archipelago terminal in the city centre across from First Hotel. Boats also depart from Matvik and Järnavik.
