On the Portuguese side of the nature reserve at Idanha-a-Nova an itinerary has been established for enjoying observation of the rut:
The Route of the Stags
This wide track has two alternatives and a branch for enjoying the fauna at Tajo Internacional. The starting point is Rosmaninhal, a Portuguese parish belonging to the municipal district of Idanha-a-Nova. From here we must take the road towards Fonte do Medo and then the country lanes leading to Guedelha, Vale Pórros, Rivera do Freixo, and Cegonhas. Once you have reached this village, take the road to Couto dos Correias to then stop at the survey point of São Felizes and finally come to Soalheiras.
Here at Soalheiras a path leaves the village to penetrate areas dominated by Mediterranean woodland and scrubland until it reaches Alares, an ancient abandoned hamlet built of slate. This place in ruins and surrounded by nature will give a telluric touch to your journey.
From this point the branch needs to be followed; it starts from a lane between walls which runs southwards to the former post of the Guarda Fiscal.
Another option is to go northwards and then turn to the northeast so as to reach Rosmaninhal once more.
