Grimsel Pass Old Road is an old cobblestone road located in the canton of Bern in Switzerland.
Built in the 1900’s it was the first road along the gorge. The surface of the road is cobblestone. It’s 1.2km (0.74 miles) long.
The short mountain road is often impassable from October through until late June due to deep snow cover. It leads to a beautiful, narrow gorge in the Haslital. The track starts on a parking lot. It was bypassed by a tunnel.
