Urbasa y Andía Natural Park, Navarra, Spain
The Urbasa-Andía Natural Park in western Navarre is made up of the Urbasa and Andía mountain ranges. The NA-120 road links Etxarri-Aranatz with Estella-Lizarra and runs along the Andía range. At kilometre 20, just a few metres from the road, you will find a Roman road, a thousand-year-old witness of an era in which it connected Valdega with the Arakil valley. This range contains one of the most spectacular places in the park: the Monastery of Iranzu.
