This route was planned by komoot.
The Komoot tour for the Tømmerrenna Timber Slide Trail is approximately 8.4 kilometers long and typically takes around 2 hours and 15 minutes to complete. The unique wooden flume section itself is about 4 kilometers one way.
Yes, the trail is generally considered easy and accessible for most people, including families and those with dogs. The path is largely flat as it follows the old timber flume. However, be aware of narrow sections, a dark tunnel requiring a light source, and suspension bridges that might challenge those with a fear of heights.
The trail primarily follows the trough of a 4-kilometer wooden log flume, making it largely flat. Key features include several tunnels, one of which is about 100 meters long, dark, and low (around 1.30 meters), requiring you to crouch and use a headlamp or phone flashlight. You'll also cross two spectacular suspension bridges (100m and 120m long) over the Otra River. Some sections are suspended high above the forest or river, and the wooden planks may creak or sway.
Along the route, you'll experience lush forests and views of rushing rivers. Notable sights include the Steinsfossen Waterfall, the impressive Suspension bridge on the Tømmerrenna, and remnants of the Kringsjå power station. The trail also runs partly alongside the historic Setesdal Vintage Railway, offering a chance to see old steam locomotives.
The trail is best enjoyed from spring through autumn. The autumn colors are particularly stunning. It is advised not to undertake the hike on windy days or in winter due to potential snow or ice on the wooden structure, which can make it unsafe.
Yes, the trail is suitable for hikers with dogs. Please ensure your dog is kept on a leash, especially on the narrow sections, bridges, and in tunnels, and always clean up after your pet.
No, there are no specific permits or entrance fees required to hike the Tømmerrenna Timber Slide Trail or to access Paulen Naturreservat. However, please respect the natural environment and any local regulations for protected areas.
While specific parking areas are not detailed, the trail is located near Vennesla. Hikers typically find parking at designated spots close to the trailheads. It's advisable to check local maps or Komoot's tour details for the most convenient starting points and parking options.
Given the unique features of the trail, it's essential to bring a headlamp or phone flashlight for navigating the dark, low tunnels. Comfortable walking shoes are recommended, along with water and appropriate clothing for the weather. Consider bringing a light jacket even on mild days, as sections can be exposed.
Yes, there are a few. The wooden planks of the flume may creak or sway, which can be daunting for those with a fear of heights, especially on the suspension bridges. The tunnels are dark and low, requiring a light source and bending. It's also strongly advised to avoid hiking on very windy days or during winter due to snow and ice, which can make the path slippery and dangerous.
Yes, sections of this route overlap with other official trails. You will find parts of the Tømmerrenna trail itself, as well as portions of the Nasjonal sykkelrute 3.
