Discover South Koster by bike
Strömstad

Discover a fantastic part of the Bohuslän archipelago

Quiet lanes, sandy beaches and beautiful sea views make South Koster a lovely island to explore by bike. The larger of the two Koster Islands, it offers plenty of reasons to slow down, from a picnic by the water to a leisurely lunch at a local restaurant.

Much of the islands is protected as a nature reserve. Follow the roads and cycle routes shown on the map, and leave your bike behind when exploring the walking trails.

Getting here

Passenger ferries depart all year round from Norra hamnen (the North Harbour) at Ångbåtskajen, beside the main square in central Strömstad. On South Koster, you can get off at Ekenäs, Långegärde or Kilesand. Allow around 45 minutes for the crossing, depending on your stop.

You can bring your own bike free of charge, subject to space on board.

Ekenäs - Långagärde

From Ekenäs, head west towards Torget, then follow the signs towards Långegärde. Allow time to stop along the way: park your bike by Koster Church and climb the steps up Valfjäll for sweeping views across the islands and Kosterhavet National Park.

Before leaving Ekenäs, visit naturum Kosterhavet, the national park’s visitor centre, to discover the marine life beneath the surrounding waters. You can also look for the large-leaved lime tree, known locally as Bohuslinden and rare in Sweden. Follow the signs by the tennis court near Solkoster.

Fancy a swim? Make a detour to Rörvik, where you’ll find a beach and a snorkelling trail.

Långagärde - Kilesand

From Långegärde harbour, cycle south towards Torget, then follow the signs to Kilesand. Take your time and use the map to explore the smaller roads along the way.

For a break with a view, head towards Brevik for a picnic by the sea, or leave your bike and walk up to the Ramnefjäll viewpoint. Finish at Kilesand’s sandy beach, where you can relax or enjoy a refreshing dip.

Bike rental

You’ll find Kostercykeln bike hire at Ekenäs and Långegärde. Pick up your bike at one harbour and return it at the other, giving you the freedom to explore without retracing your route.

Before you set off

Pack swimwear, drinking water and something for a picnic. If you’re planning a café or restaurant stop, check opening hours before your visit, especially outside summer.
