The Maastricht-Vaals tram line walk is an approximately 48-kilometre long walk that starts in Maastricht and ends in Vaals. The walking tour is divided into four parts of approximately 10 kilometers with public transport at each start and end point. The walking tour was created by Léon Gulikers, who came up with the plan to take a walking tour on the disappeared tram line Maastricht-Vaals, 100 years after the official opening in 1922, along the remaining elements of this tram line that were discontinued in 1938.
