Green Ways are old disused railway lines which have been converted into cycling trails with gentle slopes and no motor vehicles.
The Green Way follows the route of the old Val de Zafan railway. This line was designed to run from Puebla de Híjar to the Mediterranean with the aim of connecting Aragon to the sea for commerce and trade reasons. Although the first stretches of the line were constructed at the end of the nineteenth century, it did not reach Tortosa until 1942 and here work stopped. The final stretch from Tortosa to the coast at San Carles de la Ràpita was never built. The railway was only in use for a further thirty-one years before a series of problems led to the line closing on 17 Setember 1973.
