Exploring the Idrija 177: A Technical Ride Through Slovenia’s Heartland

The Idrija 177 is situated in the western part of Slovenia, within the Goriška region, and is closely associated with the town of Idrija. The road begins near Idrija and traverses the settlements of Vojsko, Čekovnik, and Vojskarska ulica, forming a loop that is both remote and embedded in the region’s hilly landscape. Idrija itself is a UNESCO World Heritage Site, known for its mercury mine and lace-making tradition, making it a point of interest for travelers. The route’s proximity to Idrija ensures that amenities and services are accessible before or after the ride. An interactive map showing the Idrija 177 route can be found at the end of this article.

The Idrija 177 stretches for approximately 12.4 km (7.7 miles), with an elevation range from 354 m (1,161 ft) to 1,078 m (3,537 ft). The road is predominantly asphalt, but the surface quality is below average, requiring riders to be vigilant for potholes, uneven patches, and occasional gravel. The route is very twisty, with frequent sharp bends and elevation changes, making it suitable for experienced riders seeking a technical challenge. The majority of the road is single-lane (about 96%), with sections varying from narrow to moderately wide. Approximately 52% of the route is of middle width, while 26% is wide and 13% is narrow. About 27% of the road passes through inhabited areas, with the remainder winding through forests and open countryside. The combination of tight corners, variable road width, and moderate surface quality means that speeds are generally low, and caution is advised, especially in wet or cold conditions.

While the Idrija 177 is primarily a technical riding route, the surrounding area offers several attractions worth exploring. The town of Idrija Mercury Mine is a UNESCO-listed site and provides insight into the region’s industrial heritage. The Idrija Lace Museum showcases the town’s renowned lace-making tradition. For those interested in natural beauty, the Vojsko Plateau offers panoramic views and hiking opportunities. The settlements of Vojsko and Čekovnik are small but provide a glimpse into rural Slovenian life. Riders may also wish to visit the Idrija Castle, which houses a museum dedicated to the area’s history.

The Idrija 177 is generally open to motorcycles throughout the year, but seasonal closures can occur due to snow, ice, or maintenance, particularly at higher elevations near Vojsko.

There are no permanent restrictions for motorcycles, but temporary closures may be implemented during adverse weather or local events. Riders are advised to check local traffic updates or the Slovenian Traffic Information Center before planning their journey.
