The Klingenstock hike in Stoos offers a stunning ridge trail experience with breathtaking views of Lake Lucerne. Starting with a ride on the steepest funicular in the world, hikers can then take a chair lift to the ridge and enjoy a moderate 2-hour hike to the Fronalpstock viewpoint. The trail is well-built but can be challenging due to steep slopes without railings, so it's best suited for sure-footed hikers looking for a memorable alpine adventure near Lucerne.
