Exploring the River
Consider renting a kayak or canoe to explore the river's scenic stretches.





The Otra River is a significant natural landmark in the Sørlandet region of Norway, stretching 245 kilometers and ranking as the country's eighth-longest river. Originating in the Setesdalsheiene mountains, it flows through various municipalities, including Bykle and Kristiansand, before emptying into the Skagerrak. The river is renowned for its 12 hydroelectric power plants, which contribute significantly to the region's electricity supply. Its waters are also favorable for salmon, thanks to the calcareous rocks in the catchment area that buffer against acidification. This makes Otra a perfect destination for those interested in both natural beauty and sustainable energy.
