Gull Sandbank Nature Reserve protects the shifting sandbanks at the mouth of the Vistula, where the river meets the Gulf of Gdansk. The landscape is always being remade by current and wind, which makes it one of the better places around Sobieszewo for birdlife.
Come in late spring or early summer and you may spot gulls and seals resting on the temporary islands offshore. Bring binoculars: the best wildlife is often visible only at a distance, and that is part of the point.
