Stampen and Onsbæk Beach are located just south of Rønne and form a long, calm sandy beach with plenty of space. The seabed consists mainly of sand, while further offshore it may vary with stones and more rocky sections. The water becomes gradually deeper, and around 100 metres from the shore it reaches a depth of approximately two metres – a condition that may naturally change with wind and currents.
Behind the beach lies a green area with holiday homes and natural surroundings, and parking is available close to the beach access points. As there are no kiosks or public toilets on site, Onsbæk Beach has retained its quiet and simple character, making it well suited for visitors seeking an undisturbed beach experience close to Rønne.
The bathing water generally has good quality and stable conditions, providing a safe basis for swimming.
