There is an information board by the parking. Walk ca. 50 meters to a bridge where you will find signs for Vatnasetenuten and Tostøl. This hike is a roundtrip and this trail description describes going in the direction of Tostøl first. The level of difficulty is very similar if you choose to go in the opposite direction. Walk across the bridge to Tostøl. The path is relatively easy, but there are some slightly challenging parts. There are some wet sections of the trail where larger rocks have been laid out. After about 1 hour you arrive at the top of Saurdalen, where the trail divides and you can choose if you want to go to Vatnasetenuten or Tostøl. Follow signs for Vatnasetenuten. After some slightly challenging sections you will be rewarded with great views in all directions. Keep walking north all the way up to Vatnasetenuten. The views from the top are great. The trail from the top and down towards Våhaug is steep in the beginning, but other than that it is fairly easy.
