We leave Tortosa following the Via Verda de la Val de Zafán, an old railway line converted into a cycle path that runs along the course of the Ebre river. The route is practically flat and very comfortable, passing through the villages of Aldover and Xerta, where the river and the farmland set the pace. We leave the greenway and cycle a short stretch along the road before turning off onto a secondary road towards Paüls, a solitary and pleasant stretch that winds through Mediterranean forests.
