This site is a small island. There are vertical and overhanging walls on the S and W sides, with ledges near the top. Plenty of fish life.
There is a wreck here at 60m on the S side. The Boknasund was a small wooden vessel built in 1944, and used for fishing and general cargo. She hit the Nappholmen in April 1971 whilst carrying a load of sand. Divers report that most of the hull has gone, with the bow and stern being the most intact parts.
