For those planning to hike in the Alegrete area, the main reference route is the PR3 PTG – Percurso de Alegrete. This circular route offers a complete immersion in the Serra de São Mamede Natural Park, combining the medieval heritage of the village with montado landscapes and water lines. The Main Route (PR3 PTG) The PR3 PTG - Percurso de Alegrete is about 11.4 km long and is classified as medium/low difficulty. The recommended starting and ending point is near Fonte Nova, although many hikers start their journey in the village of Alegrete itself to explore the historic center right away. Castle and Village: The Castle of Alegrete is the (literal) highlight of the hike. Situated at about 500 meters above sea level, it offers a panoramic view of the Alentejo border region. Don't miss the Clock Tower (Torre do Relógio). Nature and Biodiversity: The trail crosses areas of cork oak montado, pine forests, and riparian areas. It is an excellent place for bird watching (such as the robin or the titmouse) and, near the water lines, you can find rare vegetation like the royal fern. Religious Heritage: During your passage through the village, you can also visit the small Chapel of Mercy (Capela da Misericórdia), which is part of the local historical complex. Practical Hiking Tips Time of Year: Avoid the months of July and August due to the extreme temperatures in the Alentejo. Autumn and spring are ideal for the colors of the vegetation and mild temperatures. In winter, be careful with the ground, which can become quite slippery on cobblestones and rocky trails. Equipment: Use footwear with good grip (the ascents and descents to the castle and river have sections of loose stones). Bring enough water, as outside the village, refueling points are scarce. Safety and Respect: Always follow the official signage (yellow and red marks).

Hiking to Serra de São Mamede (1027 m), the highest point in continental Portugal south of the Tagus, offers a unique experience that combines the hardness of quartzite with the freshness of lush vegetation in the Serra de São Mamede Natural Park. The ascent rewards hikers with panoramic views that extend to the Estrela and deep into Spanish territory. For a safe and rewarding hike on this peak in Portalegre, consider the following advice: Route Planning: There are several trails leading to the summit, with the Serra de São Mamede Walking Route (PR1 PTG) being one of the most popular. The path is often rocky and steep, requiring footwear with good traction and ankle support. Water and Energy Management: The physical exertion and sun exposure, especially in the higher, unprotected areas, require you to carry sufficient water (at least 1.5L) and energy snacks. There are no reliable supply points during the ascent. Pay Attention to the Weather: The weather in the mountains can change rapidly. Even if it is sunny in the city, the summit may be shrouded in fog or strong winds. Always check the local forecast before setting off and bring a windbreaker or warm clothing. Sun Protection: Due to the altitude and sparser vegetation on the summit, UV radiation is more intense. Use sunscreen and a hat, even on cloudy days.
