Frequently asked questions

On this page you will find the answers to some of our most frequently asked questions about Koster Islands. Do you need more help? Please do not hesitate to contact us infocenter@stromstad.se

The Koster Islands are tucked high up the north-west coast of Sweden near the border with Norway and the Koster ferry take you to the Koster Islands every day, all year round. Both islands have a variety of landscapes dotted with red-roofed houses with lovely swimming beaches, moors, small forests and rocky coasts with clear traces of the Ice Age. These two main islands have 300 year-round inhabitants (240 of them at South Koster) and since both are virtually car-free, attract large numbers of cyclists and hikers in the summer.

Remember that a large part of the islands is a nature reserve and at the Koster boat landing piers there are information signs with maps of routes and trails. If you are bringing a dog, it must be on a leash.

South Koster has an area of 8 square km and North Koster an area of 4 square km. Tiny North Koster is hilly and has good beaches. Larger South Koster is flatter and better for cycling, with bike-rental facilities, restaurants and two large beaches at Rörvik and Kilesand. You’ll also find Sweden’s national marine park, Kosterhavet National Park, here – a home to 12,000 species of marine life and Sweden’s largest seal colonies.

Where can I go swimming?
Smooth rocks, secluded bays and sandy beaches surrounded by a glittering sea. The Koster Islands are one of the sunniest places in Sweden and well-known for offering wonderful opportunities for sunbathing and swimming. On North Koster you can go swimming near Västra bryggan, Basteviken and Norrvikarna up north. On South Koster there are large beaches such as Rörvik outside Ekenäs and the kilometer long sandy beach at Kilesand. More information. 

Where can dogs go for a swim?
Dogs are able to swim anywhere and as a owner you are still obliged to keep their dogs on a leash and to clean up after their dogs.

On both North Koster and South Koster there are several different marked hiking trails and circuits. They take you through dim pine forests and deciduous groves, across heaths and bare rock and down to damp seashore meadows. But the North island has a different feel, much wilder and desolate with white sandy beaches. Enjoy the stunning scenery from the marked paths and trails, or from the various resting spots. 

You can cycle between different attractions on smaller roads on South Koster.

View point?
Valfjäll on South Koster, accessed by steep wooden steps, gives a great panoramic view including the shingle church down below and the ocean in the distance.
Högen (lighthouses) on North Koster, it is worth climbing up to the lighthouses to see the panorama across the islands and the horizon.

I enjoy being in the nature, where should I go?

On North Koster there are two marked circular routes that let you walk to the varying land and seascapes easily. Distances are comfortable so you don’t really have to plan ahead and there are plenty of interesting detours. Look out for: the shingle fields at Valnäsbukten (bay) are a stunning remnant of the ice age and the sea that formed the ramparts as the Kosters rose from the sea. Visit Kosters highest vantage point at Högen where there are two former lighthouses at almost 60 metres above sea level for fabulous views. Go for a dip, weather allowing, at Basteviken, Norrvikarna and Hasselvikarna. 

There are four colour-coded walking trails on South Koster between the harbours and paths that go around and criss-cross the island. Look out for: Valfjäll with jaw-dropping views across the Koster Islands. Visit the Koster gardens and sculpture park. Pretty sea holly and the Koster thistle at Kilesand beach. The leg from Kilsand to Brevik harbour goes over a plant-rich shoreline and meadows and you enter the national park; one of two areas of South Koster island that is part of the national park.
