Boat trips run from Strömstad’s north harbour to the beautiful cluster of forested Koster Islands every 30 minutes from July to mid-August, less frequently at other times. Tiny North Koster is hilly and has good beaches. Larger South Koster is flatter and better for cycling, with bike-rental facilities, numerous restaurants scattered about and two large beaches at Rörvik and Kilesand. Trips are booked through the tourist office.
