The Tømmerrenna in Vennesla is the only surviving timber flume of its kind in Norway: a four-kilometre wooden channel built between 1952 and 1957 to transport logs along the Otra river after a hydroelectric dam disrupted the traditional log-floating route. It operated until 1981 and has since been converted into a walking path.
The walk follows the flume itself, crossing two suspension bridges of 100 and 120 metres and passing through tunnels. The terrain is almost flat, making it accessible for most ages. The round trip takes about two hours. Restoration work started in 2024 to preserve the weathered wooden structure while keeping it safe for visitors. It is a unique piece of industrial heritage in a beautiful river valley setting.
