Easy hikes and walks around Mouronho

Bridge built over the Cavalos River, with a deck approximately 50 m long and 3 m wide. It probably forms part of the same road link as the Roman road of Pedra da Sé, serving as a connection between the Roman civitas of Bobadela and that of Viseu. It has only one arch with a perfect semicircular span, and the pavement that forms part of the deck is the result of intervention after the time of construction. It has been classified as a Property of Public Interest (IIP) since 1990, by Decree No. 163 of July 17, 1990.

The Fraga da Pena Waterfall, located in the Serra do Açor Protected Landscape, is a geological feature crossed by the Barroca de Degraínhos, creating a series of successive waterfalls. The waterfall is 19 meters high. Along its banks are some ancient specimens of the Portuguese oak (Quercus robur) and the chestnut tree (Castanea sativa), as well as the strawberry tree (Arbutus unedo), the thorny Daphne gnidium, and the adernos (Phillyrea latifolia and P. angustifolia).

Small but very pleasant river beach (without sand) on the course of the Rio de Cavalos.

The Roman Bridge of Sumes, with its round arch, is a stone masonry structure measuring approximately 6.4 metres. It stands over the Cavalos River, in a natural setting, punctuated by enormous granite rocks and crisscrossed by dirt paths. This is where the fantastic Trilho dos Gaios begins (or ends), winding along the Cavalos River between several waterfalls and lush vegetation.

In the heart of the protected landscape of the Serra do Açor, Fraga da Pena is a natural spectacle sculpted by time. The Barroca de Degraínhos creates a succession of waterfalls, culminating in an impressive 19-metre cascade that descends in crystal clear veils over the rock.

The Roman Bridge of Sumes stands over the River des Chevaliers, shrouded in mystery. Although its foundations appear to be Roman, the exact date of its construction remains uncertain. An inscription reading "80 AD" found on a nearby wall suggests its origin, but some historians believe it refers to an ancient spring. In the surrounding area, traces of medieval paving can still be seen. Regardless of the bridge's uncertain age, it is classified as a Property of Public Interest, having witnessed centuries of history.

In summer, the river beach of Vale de Gaios becomes a little paradise for those looking to cool off. Its crystal-clear water, formed by the Cavalos River, a tributary of the Mondego, invites you to take a refreshing dip and spend long moments in the sun. On hot days, there is no better place to enjoy nature and recharge your batteries!

The colourful walkways of the Trilho dos Gaios start at the river beach of Vale de Gaios and lead you to the ancient Roman Bridge of Sumes. Along the way, you will pass by the winding banks of the Cavalos River, a wild tributary of the Mondego, which hides among the lush vegetation and moss-covered rocks, as if it were something out of a fairy tale. In some parts, it disappears completely under gigantic blocks of granite, with only the gentle murmur of the water revealing its presence.
