It is a beautiful day, the water of the Elja River skillfully finds its way. It flows and ripples serenely along and over rocks and boulders, surrounded by the lush green of trees and bushes. Where the stone is wide or the sunlight can make its way through the dense forest, the peaceful natural spectacle reveals itself in a particularly beautiful and glittering way. In its rocky bed, the river meanders so peacefully at first, then almost becomes a lake whose water hardly seems to flow. But nevertheless it gets louder here, because not far away Elja falls powerfully and thunderously into the depths at the Elgafossen waterfall. How powerfully and fundamentally conditions in nature can suddenly change.
