The Rembesdalsfossen is a regulated waterfall with a rather tiny stream or most of the time no stream.Right below Kjeåsen, at the beginning of the Simadalen is the second largest powerplant in Europe. I think in periods of extreme rainfall the waterfall will flow and is ready to be visited.
The Løfallfossen is a waterfall downstream of the Rembedalsfossen. Also with so little water in it that it isn’t worthwhile to visit.
A little bit back into the Simadalen,on the opposite side off the valley, you will find the huge, powerful and impressing Skytjefossen. One of the best waterfalls in Hordaland you can visit. When standing in front of the fall you will feel how tiny and fragile people are. The water of the Skytjedalsvatnet thunders down with a great force over 410 meters.
The Simadalen is a valley east of Eidfjord in the region Hordaland. From Eidfjord it a 10 minute drive (8 kilometers) to the east over road Fv103. At the end of the road it is a short walk of 20 minutes to the Skytjefossen. After that you can find the Løfallfossen at the end of the valley, almost at the base of the Skytjefossen. I am not sure if it is possible to walk further on th eREmbedalsfossen. But if there is hardly any water in the Løfallfossen, you better stop there.
