This themed trail is dedicated to electricity and technological culture, and tells visitors about the beginnings of hydroelectricity production at 12 points along the way. The electricity promenade starts in the center of Marling at the advertising column and leads to the different points of discovery that are several hundred meters apart all along the route. Highlights of the walk include the underground cable which supplied power to the cities of Bolzano and Merano as long ago as 1905, and the Marling Power Station water chamber dating from 1925.
