The Koster Islands
Strömstad

Discover Koster all year round

Almost the same distance from Oslo (130 kilometres) and Gothenburg (160 kilometres), Strömstad is ideally situated between two of the most vibrant cities in Scandinavia. Strömstad has the saltiest water on the west coast, and is the location of the Kosterhavet National Park, the only marine national park in Sweden. Just 45 minutes by boat to the west, the Koster Islands offer excellent opportunities for walking, kayaking and cycling.

Remember that the choice of activities, and opening times of restaurants, shops and hotels vary over the year. Check the companies’ own websites for current information.

The islands are to a large extent nature reserves, and you will encounter a lovely mixture of coastal meadows with a rich flora, rolling countryside, and a windswept outer archipelago.

Walk or cycle on South Koster

South Koster is ideal for exploring on foot or by bike as the island has virtually car free.

If you don’t have a bike with you, you’ll be able to hire enough for the whole family from April to October near several of the ferry landings on South Koster. the ferry landings on South Koster.

Hiking on North Koster

You can easily make your way to North Koster directly from Strömstad. During the summer and on public holidays in spring you can also travel by cable ferry between the two islands North- and South koster (Västra Bryggan-Långegärde). If you travel to North Koster outside peak season, remember to bring something to eat and drink for the whole trip as there is no shop on the island that is open all year round. During summer there are restaurants open on North Koster.

On North Koster there are two main signposted walking trails, 5.4 kilometres and 5.5 kilometres long, passing through rich and varied natural landscapes. Along the trails there are many opportunities to make a detour. Högen Hill, with Koster’s two lighthouses, is 58 metres above sea level. It is the highest point on the Koster Islands and provides a stunning view. If you want to go for a swim, you can do so both from the beach or the rocks.
