The PR4 ARL - Route of the Sobreira Grande is a circular trail starting in the village of Vale de Pereiro, in the municipality of Arraiolos. With approximately 10.4 km, it crosses rural paths, agricultural land, cork oak and holm oak montado areas, and places close to watercourses.
The main point of interest along the route is the Sobreira Grande, a remarkable cork oak tree recognised for its natural value. The trail approaches the tree after following a watercourse, allowing visitors to observe the relationship between the montado, the rural landscape and the natural features that characterise this area of the Alentejo.
The route continues through montado areas and alongside the stream to the Santa Luzia Bridge, another of its most relevant features. The return to Vale de Pereiro follows rural paths and the village's surroundings, completing a walk marked by montado woodland, natural heritage, and the local agricultural landscape.
The Sobreira Grande, which gives this trail its name, was elected Portugal's Tree of the Year in 2022 and achieved 3rd place in that year's European Tree of the Year competition.
