The Ultimate Road Trip to Petrohan Pass in the Balkan Mountains
Petrohan Pass is a mountain pass at an elevation of 1.407m (4,616ft) above the sea level, located on the boundary of Montana and Sofia provinces, in Bulgaria.
Is Petrohan Pass in Bulgaria paved?
Set high in the Balkan Mountains (Stara Planina), the road to the summit is totally paved. It’s called Route 81. It’s the shortest route between Sofia and north-western Bulgaria (and from there Romania). Access to the pass is typically open all year round, but winter weather may cause restrictions and closures due to dangerous weather conditions.
How long is Petrohan Pass in the Balkan Mountains?
Tucked away in the northwestern part of the country, the pass is 41.2 km (25.60 miles) long running north-south from Barzia to Buchin Prohod. There are plans to improve the road building a tunnel. Chinese investors are interested in building the tunnel under Petrohan and expanding the existing highway. A tunnel under Petrohan pass will shorten the Lom-Sofia road by 70 km.
