The River Guadiamar rises at El Castillo de las Guardas and an affluent on the right bank of the River in the Doñana marshland.
The Metropolitan Green Corridor connects La Corchuela Periurban Park with various municipalities in the Seville Metropolitan Area through two bicycle lanes. This encourages the use of non-motorised transport, without overlooking the significant opportunities for recreational and tourist use, given its landscape quality and cultural and architectural heritage.
We leave Aznalcázar on the old Aznalcázar-Pilas road, and 200m further on we will find the Guadiamar Visitor Centre, where the Green Corridor begins. On leaving the town centre we take the path that starts on our left, to follow the route along the right bank of the Corridor, so that the Guadiamar will always be on our left.
