Many people drive by the Espelandsfossen (R13) without noticing this huge waterfall, because 200 meter further up the road is the famous Låtefossen. From the car parking at the Latefossen it is a short walk to the Espelandsfossen and it is really worthwhile visiting. With a tremendous waterflow the Espelandsfossen is impressive to see.
Even in May (I was there in 2015) the waterflow was really enough for good pictures. Early in the morning the sun shined half on the Espelandsfossen giving a nice contrast. There are several good viewpoints at the Espelandsfossen: right in front of the fall photographing towards the west and a very nice viewpoint from the path next to the Låtefossen going up to the remains of a hotel. Here you will have a good view on the Espelandsfossen from a higher viewpoint photographing towards the west-southwest.
Although the Espelandsfossen is only 80 meters high is has a massive amount of water falling down in (early) summertime with a volume of 4m3/sec. You can see the difference in the pictures: the first 4 are taken in june-july and the rest of the pictures in the beginning of May.
There is also a waterfall called Espelandsfossen near Granvin and a Espelandsfoss near Espeland at road 503. But this is the more impressive one with a height over 1oo meter plunges down over two cascades, 55 meters+25 meters (one visible).
