Here you will find a water-filled Alentejo all year round, a transitional space between the mountainous areas to the east and the floodplains to the west. The oak groves are vitally important not only because of cork production but also because they ensure very biodiverse ecosystems, enriched by fabulous megalithic remains. It is a constantly-changing landscape with horizons stretching to infinity, deep valleys and the possibility of walking along what was once an important regional railway line.
