Welcome to Nordkoster Sweden's westernmost outpost and a Mecca for nature enthusiasts . The guest marina is located right in the strait of the Koster Islands. Nordkoster is a gem that should not be missed. Further out is the Koster archipelago and if you continue here you will end up in England. Nordkoster is located in the new marine Kosterhavets national park. The majority of the island is a nature reserve. Nordkoster is best explored by foot, and there are no cars on the Island. The road network is largely composed of gravel roads and trails. If you want to swim, there are many lovely beaches, as for example Bastviken and Björnsängen on the west side of the island and Norrvikarna and Familjeviken on the north and east side.
