Of the five major waterfalls in Oddadalen, Strondsfossen may not be the smallest but because it is generally viewed from across a large lake, it is certainly the least appreciated. Fed by melt from the Folgefonna Icefield as well as seven major lakes, Strondsfossen is a moderately high volume waterfall which drops about 1,240 feet directly into Sandvinvatnet. Overall the waterfall is classified as a Steep Cascading type waterfall, but in reality the falls alternate from plunging to cascades to sliding and back. The initial drop is essentially back-to-back free falls, reverting to slightly less than vertical falls after that. From the middle of the falls to its base Strondsfossen features multiple smooth but steep slides where the water sheets out over broad reaches of bedrock. Because of these final slides the falls have a run of over 2,000 feet, though when viewing from across the lake, there is no indication of the length involved.
