Gästhamn Kalvsund

Tucked on the eastern side of Kalvsund — the smallest and car-free island in Öckerö kommun — this marina sits in Gothenburg's northern archipelago between Bohus-Björkö and Öckerö. You'll find Y-booms or stern-to mooring, with depths of 3.5–4 m and a harbour master on hand year-round if you need a hand docking. Modern showers, toilets, and laundry are all included in the harbour fee. The setting on this tiny, traffic-free island is genuinely peaceful, and the harbour office and service building are right alongside.
