Portugal's Nature Parks
The highest mountain range in Portugal is the Serra da Estrela. The episode embarks on a voyage of discovery to adventurous rock formations and villages steeped in tradition. The nature park is the largest protected area on the Iberian peninsula. In the mountain range we accompany the young scientist Ana Matos, who wants to breathe new life into old traditions, and cheese maker Maria Natália Lopes. She watches over more than 350 sheeps.
