This small cluster of rocks in open ocean offers multiple dive sites. South/south-west side starting with boulders changing to sand bottom between 16 and 22 meters. Good fishlife here. On the line between the southern most rocks there is a steep wall with corals and anemones. North and east the bottom slopes gentle, covered with boulders and rocks. Less plants and softcorals here, but good fish-life.

This dive site is easy to navigate, often with good visibility but prone to surface currents and waves.

Kostersten is a cluster of 4-5 rocks with a small "lagoon" in between. The largest rocks is facing west.
