About this site
Helvetessundet is a narrow sound along the southern coast of Norway, in the Skagerrak area near Grimstad in Agder county. Its name translates roughly to "hell's strait," a reference likely tied to tricky currents or navigation through the passage. The site sits among the skerries and inlets typical of this stretch of the Norwegian coast, where the terrain drops from rocky shoreline into the Skagerrak.
