Boats depart at up to 16 times a day in the high season, right next to the Tourist Information Centre (travel time about 1 hour). The islands are ideal for a trip of one to several days. The trips are car-free. Bicycles can be used on Sydkoster and on a few main routes on Nordkoster, which for the most part is a nature reserve. The reserve is a good destinations for a day trip; it can be circumnavigated by a walk of about 1.5–2 hours pure walking time. On Sydkoster, the Natureum at Ekenäs brygga is a good destination. There are restaurants on both islands, but only on Sydkoster a supermarket (in the middle of the island; Su closed). Accommodation must be booked in advance, also the campsite on Nordkoster.
The Koster Islands situated 10 km west of Strömstad, Sweden, comprises an archipelago surrounding the two largest islands, South Koster and North Koster. South Koster has an area of 8 km2 and North Koster an area of 4 km2. The landscape, dominated by smooth bedrock, bears witness to volcanic activity and subsequent wear due to the Ice Age. The rocky coastline is broken by many sandy beaches, the largest being Kilesand on South Koster's east side overlooking the 200 meter deep Koster Fjord.
