Raudfeldsgja Gorge

This is an obvious gorge in Botnsfjall Mountain as you are driving. A short side road goes to a parking area and the trail is visible going up and into the crack in the mountain. Raudfeldsgja is transcribed as Red-Cloak Rift. Indeed, in summertime, you can go inside and look around. You can only get a short distance before it narrows and would require getting very wet to explore further, nobody was attempting it.
