The power plants of the Grimsel region are truly hands-on experiences. A world where you can discover everything you’ve always wanted to know about electricity. Hydropower requires sophisticated technology. Deep within the mountain, life pulses—this is where the turbines of the Oberhasli power stations run at full speed all year round. Experience the Grimsel Underground with an up-close look at the Grimsel 2 power plant and let yourself be enchanted by the shimmering crystal grotto.
