The river Driva reappears from under the rocks at Mågålaupet. Fifty meters upriver the whole river entered a very narrow gorge and at the end disappears completely under the rocks.
The Driva river runs through Sør-Trøndelag and Møre og Romsdal counties in Norway. The headwaters lie in the Dovrefjell mountains in the south, from where it flows northward, downw through the valley Drivdalen to the municipality of Oppdal. In Oppdal is turns westward down Sunndalen walley to the Sunndalsfjord at Sunndalsøra in the municipality of Sunndal.
The descent through Drivdalen to Oppdal cascades swiftly down a confined course. At Magalaupet (approx. 10 km south of Oppdal) it is so narrow that it is possible to jump across - if you are a good jumper! If you miss the landing or jump to short, the resulting bath in the river is almost certainly fatal.
