Near Sauda there are several named and unnamed waterfalls. The Fossdalsfossen is an unnamed waterfall in Google maps but is named in Norgeskart. Studying the map and the photo the waterfall is 60 meters high.
From Sauda take the Rv713 (Espelandsvegen) into the Åbødalen. The road ends at Buer, just the point where the Fossdalsfossen is falling down. Nearby there is tourist attraction with potholes: „Jettegrytene i Åbødalen“
From the Fossdalsfossen it is a short walk (heading North) to the Moringdalsfoss, a little bit upstream the Moringsdalselva. It is a nice waterfall with a vertical dropdown of 25 meters. I am not sure if it is easy to find.
