We got a tip in the climbing shop Vertical Playground in Oppdal to go for Tøftfossen Wi4. It's close to the Drivstua Trainstation. But instead going towards the trainstation, go towards the farm. There is a new stable. You have to go around the stable to see the bridge, which you have to cross. Follow the road till the Grubbekken crosses the road. Keep south of the stream. Towards the end you better desend to the frozen stream. For the descend got west and then north around the bowl und start the descend, when the mountain side is not that steep anymore.
