Štrekna Railway Tunnel

The Štrekna Railway Tunnel in Koroška is a fascinating blend of technical heritage and outdoor adventure, offering visitors a unique way to explore Slovenia’s industrial past while enjoying the region’s natural beauty. Originally part of the Velenje–Dravograd railway line, which opened in 1899, the tunnel is one of several constructed to overcome the challenging terrain of northern Slovenia. Over 2,200 workers contributed to this ambitious project, which includes the impressive Huda Luknja tunnel at 421 meters long.

Today, the Štrekna Railway Tunnel is a highlight of the Štrekna cycling route—a scenic, 35-kilometer path that follows the old railway line through six tunnels and across numerous bridges and viaducts. The route is fully paved, separated from traffic, and suitable for families, leisurely cyclists, and seniors. As you ride through the tunnels, you’ll experience a cool, atmospheric journey beneath the Pohorje Hills and Mount Uršlja, with the dramatic Huda Luknja gorge adding to the adventure.

Along the way, you’ll find designated resting spots, amenities, and points of interest such as the highest church in Slovenia and the historic city center of Slovenj Gradec. The Štrekna path is more than just a cycling trail—it’s a living monument to the ingenuity and determination that shaped the region’s landscape.

Whether you’re a history buff, a cycling enthusiast, or simply seeking a memorable day out, the Štrekna Railway Tunnel offers a unique window into Koroška’s past and present.
