Getting to the Hotel Rothorn Kulm (2266 m.a.s.l.) is quite an experience. No prosaic getting there by car or even by aerial cable-car but by steam-driven rack-and-pinion train. The ride there can even be made more romantic by getting to Brienz by a paddle-steamer from Interlaken plying Lake Brienz and Lake Thun.
The photovoltaic solar power station operates on Mount Soleil. Wind turbines stand on Mount Crosin.
