Cross-border Contraband Route: This route has a length of 15 km there and back and presents no difficulties. It takes about three and a half hours to cover the distance from the Town Hall of Zarza la Mayor to Salvaterra do Extremo in neighbouring Portugal.
The route is that followed by the old smugglers to pass coffee illegally from one side of La Raya to another between Extremadura and Portugal. They would travel either on horseback or on foot, but always on moonlit nights to avoid arousing suspicion.
Montón de Trigo Route (SL-CC 142): This linear route, which has a distance of 8.8 km and presents no difficulties, can be covered in two and a half hours. It starts from the village of Zarza la Mayor and goes as far as the River Erjas, which in this area serves as a natural border with Portugal. It is a relatively short path and crosses a very interesting landscape, as among other things its end at the river offers a fine picture of La Raya.
The first section follows the Gata Royal Drovers’ Road (to coincide with the route of the same name) through an eminently stockbreeding landscape of stone walls. After leaving the drovers’ road, the route begins to descend towards the river on a lane parallel to the La Grera Stream; the terrain becomes more and more rugged until you cross a hiking pass and penetrate a rocky area where holm oaks, hawthorns, terebinths, and hackberries are abundant. Finally it crosses a small ravine with willows and ashes which takes the form of a stream before it flows into the River Erjas; a metallic walkway has been installed to give access to the viewpoint over the river. This is a good place to find vegetation characteristic of rock fissures such as friar’s cowls, ferns, and fiddle dock.
During practically the whole of the route, especially on the last section, it is easy to observe large birds of prey such as griffon vultures, Bonelli’s eagles, short-toed eagles, and buzzards together with numerous small birds such as serins, goldfinches, Sardinian warblers, and hawfinches.
