Skjonghelleren is situated on Valderøy in Giske municipality, and is an exciting cave 57 metres up in the mountain side. The cave has got a 100 metres deep tunnel, and you can walk while standing up straight until you reach the final 30 metres.
There has been found traces of settlement dating back to the Stone Age here, when the neighbour island Giske barely had risen from the ocean after the last Ice Age. There has also been found traces of wildlife dating over 30.000 years back in Skjonghelleren, and you can hear more about it at Godøy Coastal Museum.
