The summit trip to Onglanuten (760 masl) in Suldal is a great experience for the whole family. On the descent you can stop by Perskårfossen for a refreshing shower.
The marked trail starts at the parking lot near the Gulling intersection in Suldal, and follows the road up to Stavastølen. The trail continues in a loop around Skute, until you are north of Svartavatn lake. From the lake, the easiest route to the top is readily visible. On the way down you can take the trail down past Perskårfossen falls for a refreshing shower under the waterfall. If you prefer a shorter hike, you can also come up via this route.
