Sandö Hamn (Föreningen Sandö Hamn)

Sandö Hamn sits inside the Vallda Sandö nature reserve, about 30 km south of Gothenburg — a proper wild setting for a marina with quayside berths that come with water and electricity. It's the kind of place that feels miles from everything, which is largely the point. Just be aware that when the wind picks up, the moorings can get pretty rough, so keep an eye on the forecast.
