The Riskonpöllä's Underwater Wreck Park is located right between two tiny Islands Riskonpöllä and Pieni Riskonpöllä. The Park consist a schooner Siivo that sunk in 1898 also a trawler that was sunk in the 1990s and a diving bell as well an underwater mission track. There is a buoy on the east side of Riskonpöllä for divers.
There is a relatively deep landing site between the Little Risk Owl and the Risk Owl. Valkeakari's waterway and boat route are close to the diving park. Riskonpöllä diving park is maintained by Rauma Laitesukeltajat ry: http://www.raumanlaitesukeltajat.fi/?page_id=186
