The Koster Islands

Visiting the Koster Islands is like taking a holiday from everyday life, only a two-hour drive up the lovely coast from Gothenburg. Once you arrive, you are greeted by an amazing archipelago, picturesque fishing villages in a gloriously beautiful natural landscape, breath-taking views and much more. Large parts of the islands have been declared a nature reserve and the surrounding waters are part of Kosterhavet Marine National Park.


The Koster Islands and the surrounding Kosterhavet Marine National Park offer amazing opportunities for kayaking. All the way from Ramsö and Ursholmen in the south to Saltholmen in the north are lots of small islands and rocks with inviting channels, rocky bays and beaches to explore.

Koster ferry

The passenger ferries (Kosterbåten) depart daily from the "norra hamnen" in Strömstad at the main square (torget) all year round.


The two main islands, North Koster and South Koster, are perfect for exploring on foot.

Biking on South Koster

The island has a small network of cycle-friendly roads that are pleasantly short.

Things to do & see

The stunning Koster Islands are in the centre of the Kosterhavet Marine National Park. There are plenty of things to discover once on Koster. As this is a car-free (basically) environment inside the National Park, then much of the activities here are therefore nature related. There are several hiking trails, nice cycling roads and seabased activities such as swimming, snorkelling and kayaking.


The Koster Islands offer various types of accommodation close to the sea side. Choose from the charm of traditional hotel, holiday houses, camping and apartment. If you come with your boat there are a few guest harbours on the islands and plenty of natural harbours too.

Eating out

There are many cosy restaurants on Koster, each with varying menus, often based on seafood from local fisherman, such as shrimp, oyster, crayfish, crab and lobster.


Smooth granite cliffs, secluded bays and lovely sandy beaches, surrounded by the glittering Kosterhavet sea. The options for swimming are never ending and the water is also perfect for snorkelling.

All year round

A large part of the ilands is a nature reserve with strikingly beautiful landscape and a species-rich flora. The best way to get around South Koster is by bike or on foot. North Koster is the smaller island, where walking is the best form of transportation.
