Elgåfossen, Border waterfall near Vassbotten, Sweden

Elgåfossen is a waterfall on the Elja river, which flows into the Enningdalselva, dropping 46 meters. The Sweden-Norway border runs through the middle of the falls, making it the highest unregulated waterfall in both Bohuslän and Østfold. A footbridge below the falls allows visitors to cross the border.

At the falls stood Saga, a crofter's holding recorded from 1859, with timber floating, a saw and a mill. Its mill foundation, old millstones and stone pillars of a timber flume remain around the falls, and the place was lived in until the early 1960s.

The falls are called Älgafallet in Swedish and Elgåfossen in Norwegian, both built on the river name Elja (Elgå). Near the falls stand the remains of the Saga croft from 1859, inhabited until the 1960s, with timber floating, a saw and a mill. Old millstones and stone pillars of a timber flume are still visible.

Access is from a rest area on Fylkesvei 22, about 700 metres north of the national border on the road known as the Blue-Green Route. From there it is barely 400 metres to walk to the falls, and a footbridge just below the drop lets you cross the border on foot. Paths and a nature trail run around the falls, and the river can be crossed both above and below them.

The falls are lit at night by three solar-powered lamps, so the water remains visible after dark. Just below the drop, a footbridge crosses the border stream, letting walkers stand with one foot in Sweden and one in Norway.
