Actually this is the unofficial name of a waterfall in the river Driva near Holsen. We were driving road 13 heading to a really cool waterfall region near Forde with the Huldefossen. In Holsen itself there is also an official named waterfall, the Kjerringfossen.
Nevertheless, I notices the Drivafossen and with the church in the front it looks really nice. Also there was enough water falling down to call the fall the Drivafossen.
