hiking on the Koster Islands
Strömstad

The islands are a walker’s dream

The almost car-free Koster Islands are Sweden’s most westerly populated islands and consist of the main islands of North and South Koster. Around them lie the Koster archipelago with a large number of skerries and rocky isles and the Kosterhavet marine national park.

North and South Koster islands are a walker’s dream. Enjoy the stunning scenery from the marked paths and trails, or from the various resting spots.

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. There are four colour-coded walking trails between the piers, harbours and paths that go around and criss-cross South Koster.

There are orienteering maps at the piers and around the routes. You can also down load a hiking map with marked trails here.

Walking on North Koster

There are two marked circular routes that take you easily around the island; the white route is 4 km and the orange route is 3.5 km in length. The routes cross on the north of the island and from Norrvikarna both of the routes lead back to the starting point.

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. Keep your eyes close the ground at the Valnäs marshes to spot the unique little Bohusranunkel plant. 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. On both sides of the Koster sound there are restaurants that are open summertime.

Walking on South Koster

Långegärde – Ekenäs, 3.5 km
Trail – Blue

This is a popular route that includes stretches of shoreline, winds through a forest and past open meadows and arable land. The last stretch from the main route connects with another path and you follow the blue/yellow marked trail back to Ekenäs.

Look out for: Rare Bohuslinden (lime tree) at Ekenäs that is signposted from the tennis court. Naturum Kosterhavet exhibition, fish smokehouse (Rökeriet) and Kosters’ only hotel, at Ekenäs.

Detours: At Rörvik, north of Ekenäs, there is a bathing spot and a snorkel trail. If your feet want to take you further, pay a visit to Kilesand.

Långegärde – Ekenäs via Brevik, 7 km

Långegärde – Brevik, 4 km/Brevik-Ekenäs, 3 km
Trail – Yellow

An area of natural beauty in varying landscapes of pastures and ancient deciduous forest. There are bathing spots at Bergdalen and Brevik. 

Look out for: See the old fishing harbour at Brevik with meadows beside the shore, as well as a bathing spot and picnic tables. Kosters sculpture park is also here.

Kilesand – Långevik, 5 km
Trail – Green

The trail covers the entire South Koster island on paths, gravel paths and there are many discoveries to be made both on and off-trail. At the final destination, Långevik, the sea meets meadow with the whole of the Koster archipelago in full view to the west. From Kilesand the trail goes via Bergdalen to Torget before continuing along the road to the final stretch towards Långevik

Detour: Valfjäll with jaw-dropping views across the Koster Islands. Visit the Koster gardens and sculpture park. There is a restaurant and ice-cream kiosk at Kilesand.

Ekenäs – Brevik via Kilesand, 7 km
Ekenäs – Kilesand, 3 km/Kilesand – Brevik, 4 km
Trail - Red

At Hattevik, before you reach Nästången, take a right and join the trail further on. If you follow the path you will come to marshland with a rich variety of birdlife. The trail terrain around Nästången can get difficult.

Look out for: Pretty sea holly and the Koster thistle at Kilesand beach. The last leg 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.
