Our Guided Tours will immerse you in the production of electricity from hydropower. Here at the easternmost end of the Bernese Oberland, at the very back of the Hasli Valley, electricity is produced for around one million households. On our Guided Tours, you will visit the underground facilities of Kraftwerke Oberhasli AG (KWO) and learn lots of interesting facts about nature and technology. Plan your next excursion to the Grimselwelt and you will experience hydropower at first hand.
