Take road 550 to the north from Herand quay. After 4.1 km, and slightly south of the highest point in the road (Åsleitet) you leave the main road (eastwards) and follow onto a forest road. You will find an information board there. If you continue by car this is a toll road. The pay point is 100 m in from the main road. There is a good car park at the end of the road (Våhaug). Parking at own risk.
About the trail
There is an information board by the parking. Proceed to the bridge and find the signs marking the routes to Vatnasetenuten and Tostøl. Follow the trail to Tostøl. The path is fairly easy with a few short inclines. Stepping stones have been laid out in the muddy parts. Shortly you meet a branch in the trail with markers for Tostøl and Såta. Follow the trail to Tostøl. After about 1 hour you reach the top of Saurdalen where the trail divides. Here you find markers for Vatnasetenuten and Tostøl. Take the path to Tostøl. Shortly you arrive down at the mountain cabins at Samdalsstølen with the lake Viddalsvatnet below. Tostøl is about half an hour further on.
