Sarp Falls[2][3][4] (Norwegian: Sarpefossen or Sarpsfossen) is a waterfall at Sarpsborg in Østfold, Norway.[1][5] It is the second largest waterfall in Europe by discharge, after the Rhine Falls.

This is the last waterfall on the Glomma River, which is the longest river in Norway. Sarp Falls has one of the greatest flows of any waterfall in Europe. Both Rhine Falls and Dettifoss are larger and more powerful waterfalls in Europe but, while those waterfalls have between 200 and 500 m3/s (7,100 and 17,700 cu ft/s) of average water flow, Sarp Falls has approximately 577 m3/s (20,400 cu ft/s).[6] Just above Sarp Falls is a road bridge with a vista point. There are also vista points on the east side of the falls.

River surfing

[edit]

Sarpebølgen (lit. the Sarp Wave) lies about 2-3 kilometers downstream from the Sarp Falls,[7][8][9] and is popular among kayakers and experienced surfers. The Norwegian Cup in Freestyle Paddling has been arranged here.[10] The wave is spectacular, since it is quite big in regards to river surfing. Experienced surfers have warned beginners from trying the wave, since there are strong currents which means one can easily be dragged far downstream.[11] The wave appears when the flow rate is above 800-900 m3/s. It is said that the wave is well suited for surfing on a surfboard at a flow rate from 1250 m3/s and up, and very well at around 1700 m3/s.[citation needed] Glommens og Laagens Brukseierforening provide freely available flow measurements of the river flow online.[12]
