The lookout tower was built on the Peak of Friendship above the Grandhotel Pupp in 1914. You can get to it on foot along forest paths or by funicular, which runs every quarter of an hour. The funicular ride takes only 3 minutes, on foot - about half an hour.
The gallery of the 25-meter Diana Observation Tower can be accessed by elevator or by climbing 150 steps. They say that in good weather you can see at a distance of 70 km. Near the tower is a restaurant of the same name.
