Beautiful old wooden bridge over the Aare.

Since the Wiesenberg is in the forest, this observation tower makes sense. It takes hikers above the treetops and allows a 360-degree panorama. There are panorama boards. The climb is worth it.

Aarau's old town is a great place to linger, especially on beautiful summer evenings. There are many restaurants with outdoor seating. But you can also just stroll through the alleys, admire the open city stream or visit the filming locations of The Undertaker.

During the Second World War, this tower was used as an air observation post. The forest grew higher and higher, making it necessary to expand the tower. In 1953, it was increased by 6 meters and in 1987 by a further 9.5 meters.
