Marvão is dominated by its imposing and well-preserved medieval castle. The fortified walls embrace the entire village, enclosing a maze of narrow cobbled streets, white houses with red roofs and small flower-filled squares. The views from the walls are breathtaking, taking in a vast panorama of hills, valleys and, on a clear day, all the way to the Serra da Estrela mountain range. Marvão is a true open-air museum, preserving the atmosphere and architecture of centuries past. It is on the UNESCO tentative list of potential World Heritage Sites, and is an ideal destination for those seeking history, tranquility and spectacular scenery.

Cruz do Cume is a small crossroads located in the Serra de São Mamede, in the district of Portalegre, in the northeast of Alentejo, near the city of Portalegre. It is located about 1 km downhill from Alto de São Mamede, which is the highest point in the mountain range at 1025 metres above sea level. This location is known as a good birdwatching spot, especially for species such as the crested tit and the linnet, and is surrounded by pine forests that are home to other birds such as the crested tit and the coal tit. Cruz do Cume also serves as a support and access point for outdoor activities, such as hiking and trail running, and is a stopover point for important races such as the Ultra Trail São Mamede (UTSM). In short, Cruz do Cume is an emblematic location in the Serra de São Mamede, valued for its nature, birdlife and relevance for mountain sports.

The main waterfall in the São Mamede mountain range. Difficult access. As of April 2024, it will have a viewpoint with an exceptional view of the waterfall.

Not a very spectacular walk, but a tough climb just before the most beautiful part of the walk
