All in all there are ten known copper mines and two iron mines on the Ølve peninsula. Geologically, the nine mines on Varaldsøy Island also should be figured in. The industry began at Lilledal in 1642 wth the mining of iron ore. From Jernsmauget by Dyråsen, the iron ore was sent to the iron works in eastern Norway.
There is little to say about the opportunity for surveying from the bird observation tower in Kalandsvika: 155 different bird species have been sighted in the Kalands water shed. Take your binoculars and visit the tower in late spring - early summer or during the winter half of the year. If you are lucky, you might get to see a rare bird species.

At Hereiane on warm summer days one you can walk barefoot up the hill from the fjord all the way up to 400 metres elevation. The naked, furrowed bedrock often causes travellers who see it from the north side of the fjord to wonder. Why does it look like this, and why is there so little that grows here? It is a long way to the heavy metal industry in Ålvik and Odda, and there hasn’t been a forest fire in modern times.
