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.
