The entrance to the Waalweg is located in the Raffeingasse (entrance Ultental, after 100 m at Cafè Walter first right into the Villenerweg, after about 200 m left into the Raffeingasse to directly Waalweg). The Marling Waalweg is well signposted from the Ultnerstraße and easy to find.
The entrance via the Raffeinweg is paved, but rather steep (about 200 m), then the Waalweg flat and you will find various restaurants along the route.
