About Sarp Falls

Sarp Falls (Sarpefossen) is a prominent waterfall on the Glomma River in southeastern Norway, located in the Østfold area near Sarpsborg and Fredrikstad. It is notable for its high river discharge and strong currents at the fall.

Visitors come to view the powerful flow of the Glomma at the falls and to watch fish using the constructed salmon passage. There are roadside and riverside viewpoints and a designated fish ladder area that provides close observation of migrating salmon.

The falls have long been a natural feature on the Glomma and have been modified with fish passage infrastructure to allow migratory species to bypass the strong currents. Management has combined conservation measures with public access for observation and study.

Sarp Falls sits on the Glomma River between Sarpsborg and Fredrikstad in southeastern Norway (former Østfold county). The falls are accessible from local roads and are a short drive from both town centers.

  • Access: Located on the Glomma River between the communities of Sarpsborg and Fredrikstad, with pedestrian access points and roadside viewpoints nearby.
  • Hydrology and wildlife: Noted for strong river flow at the falls and active fish passage infrastructure used to support migrating salmon.
