The Gelmer Funicular is a cable railway in the Canton of Bern , Switzerland . It links a lower terminus at Handegg, in the Haslital (the valley of the upper Aar River), with an upper terminus at the Gelmersee lake, 448 metres (1,470 ft) above.

With an incline of 106% (or 47°), Gelmerbahn was the steepest funicular in Switzerland and Europe, until the opening of the new Stoos Funicular in 2017. The Handegg terminus of the line is close to the road over the Grimsel Pass . It is accessible by car and by an infrequent PostBus service. It is technically not a funicular, which has two cars that counterbalance each other, but is propelled by a winch.
