A beautiful hike through the valley (depending on your starting point, the ascent or descent will be more pronounced). Start as early as possible, while the sun is still behind the mountain range. Online tickets only (no payment on site). Take a screenshot of your ticket (QR code). This will be scanned when exiting or re-entering (if you want to go back). Bring plenty of water. The sun will come out around 10:00 a.m. (I hiked it in October). Parking is available right next to the upper starting point. The lower trailhead is about 500 meters away (coming from Chãos, turn left before the dam).

Between Vale de Amoreira and Valhelhas, the Zêzere meanders through a flat, narrow bed, shaped over centuries by the accumulation of fertile alluvium, rich sediments left behind by the river's generous floods. Today, these deep soils support fertile fields, while from up here, the valley opens up into sweeping, breathtaking panoramas, where the landscape stretches like a living canvas of the Serra da Estrela.

I did it and I recommend it. A very pleasant route, with spectacular views. A suspension bridge creates some adrenaline for those less experienced in these walks.😂

The Mondego Walkways are a series of wooden walkways that form a pedestrian itinerary along the banks of the Mondego River and the Caldeirão Stream. It begins at the arch of the Caldeirão Dam and ends near the village of Videmonte. Walking on walkways, suspension bridges, and dirt roads, the route is about 12 kilometers long and has a cumulative elevation gain of over 600 meters. I've been there before and loved the views. I recommend it. 👍🥾

This elevated location is particularly appreciated for its uninterrupted view, which extends over an accumulation of reliefs and depressions, creating a dynamic and engaging landscape. In addition to being a breathtaking observation point, Cabeço da Azinha is also an important site for air sports enthusiasts, as it hosts a paragliding runway that hosts national and international events. Its elevated position also makes it a strategic point for the fire observation post, Ponto de Vigia Gorgulão. The local flora is rich and varied, with species such as the kermes oak (azinha, from which it takes its name), heather and rosemary, which contribute to the wild beauty of the place.

From the Alto Mondego Viewpoint, the landscape stretches on endlessly, with the river winding its way down through the steep valley. In the distance, the rubble and gravel pits that mark the region stand out. This is one of the many breathtaking views along the Mondego Walkways, where nature reveals itself in all its grandeur.
