Rafossen

Rafossen is a 42-metre waterfall on the Kvina river, about seven kilometres north of the centre of Kvinesdal in southern Norway. It is a place where raw nature meets modern engineering: beside the falling water stands a hydropower plant, together with solutions designed to help fish continue their journey upstream.

What is Rafossen?

Rafossen is one of the major drops on the Kvina. Norwegian tourism material gives the fall as 42 metres, and the water thunders down with the most force during high flow, for example during spring snowmelt or after heavy rain. The river runs through the valley that gives Kvinesdal its name.

The falls have long been a natural barrier for salmon migrating up the Kvina to spawn. Some local sources also mention historical records of the place name reaching back to the Middle Ages, but exact dates differ between accounts, so they are best treated with care.

The power plant and the salmon ladder

The biggest change in the area is the Rafoss power plant, operated by Sira-Kvina. According to the operator it is rated at 9.9 MVA, with two horizontal Francis turbines of 6.6 and 3.3 MW and annual output of around 35 GWh. Visit Norway states that the new plant opened in 2022; different sources give slightly different dates for individual stages of the project.

The fish ladder is the interesting part. It runs through a tunnel starting at the water intake at the top of the falls. A research paper on fish passage at Rafoss gives a head of about 45 metres for the plant and ladder, and states the aim of making Rafoss one of the most salmon-friendly power plants in Norway. The power station has a room for watching salmon, and a footbridge crosses above the falls.

How to get to Rafossen

From Kvinesdal, drive north on road 465. Visit Norway describes the route this way: look for a small wooden sign, turn onto a narrow road and follow it to the end, then walk about five minutes. A newer listing mentions a marked parking area near the junction. Older traveller reports mention construction work that obstructed access, so check current conditions before you go.

What to know before visiting

• Higher water flow in spring and after rain gives the most impressive view.
• The access road is narrow, and the ground near the water can be slippery.
• Combine the falls with other stops in the Kvinesdal valley and along the river.
• The salmon season is a good time to visit the observation room, if it is open.

Frequently asked questions

How tall is Rafossen? Tourism sources give a drop of 42 metres.

Where is the waterfall? On the Kvina river, roughly seven kilometres north of Kvinesdal in southern Norway.

Is there a power plant at the falls? Yes. The Rafoss plant belongs to Sira-Kvina and uses the river's drop, with a salmon ladder alongside.

Is the walk difficult? From the end of the narrow road it is about a five-minute walk, according to Visit Norway.

Can salmon get past the waterfall? The falls are a natural barrier for them, which is why a fish ladder was built to allow passage upstream.
