Around Reykjanesviti lighthouse there is a lot of geothermal area. Also it“s part of the acktiv volcano zone here in Iceland. Therefor there is a lot of rock that meet the sea at that point which make all sorts of rock formations which are interesting to see.

I have a picture of these formations from some years ago and there has been a change in them as one of the rocks has fallen down. So it“s a changing area.
