The first island you arrive to when driving to Hvaler is Kjøkøy.
I decided to stop there one day this summer of 2018 to visit 'Skams klove' A fascinating gorge -or a little very narrow 'valley' there -called Skams klove. It's actually a little tourist attraction. There are also rests after a fortress from the WW2 just above it, but not worth photographing as there's only stones left..
The gorge is 200 meter long and about 12 m deep -and quite exciting to walk.
