The swimming spot lies on an island beside a crater lake formed by an impact about 78 million years ago. Impact rocks found on the island include kärnäite, suevite and impact breccia.
The beach forms part of a lean-to shelter area with changing cabins, a fire site, an outdoor toilet and picnic tables. A bridge across a narrow strait connects the island to the mainland.
