Description of Itinerary

The path starts in the centre of Furnazinhas, in the main square. From here, follow the narrow streets lined with well-kept whitewashed houses towards the old path. Follow the path, which is flanked on both sides by stone walls, until you reach the road that winds towards Fortes, next to the picnic area.

Turn left and then take a right straight after, which will take you along a path that leads towards the Odeleite reservoir. We recommend stopping by the Furnazinhas Mine (shaft and scrapheaps can still be seen as remnants of the old copper mine). Coming back up to the junction, turn left. Turn left again at the next junction, taking the path that will lead you right up to the banks of the Odeleite reservoir, the
perfect place to stop and catch your breath.

Go back the way you came until you reach the junction again, but this time go straight ahead. When you reach the junction with the paved road, turn right and then take a left straight after. This path will take you to “Cerro Pelado”, which reaches an altitude of 231 metres. From there you’ll be able to see the hamlet of Furnazinhas.

 

What will I see?

PORTELA DO MALHÃO (Malhão Portal)
The term “portal” here is used to mean a kind of imaginary “door”. After scaling the hill towards what looks like a “door or window”, you’ll find that upon reaching it you are transported into a completely different landscape! This portal opens out onto a view of the Odeleite Slopes. As you head towards the Malhão Portal, follow the walled path to Furnazinhas along outcrops of sloped strata positioned into natural paving slabs.

THRESHING FLOORS
These can be found in the area surrounding Furnazinhas, exposed to the wind. Circular constructions, these have generally been carefully preserved due to their noble usage: separating the grain (cereal, lupin beans, chickpeas) from the straw or chaff.

BARRANCO DAS MINAS (Mine Gully)
This gully owes its name to the mine near the hamlet and which it runs alongside. The distance from the gully to the Odeleite Stream, which the water in the gully flows into, is very short, which means that no “barrancadas” (name given to the phenomenon that takes place when it rains heavily, increasing the amount of water in the gully quickly and drastically, which can be dangerous) are formed, a phenomenon that is often seen in the gullies that join the Foupana reservoir.

FURNAZINHAS MINE
Known locally as the Caieiras mine. “Caieiras” is a word used to describe a hillside that is completely devoid of vegetation. It was here that the ore became exposed once washed. The water running over the ore due to this process led to the soil becoming acidic, thus preventing any vegetation from growing. Though it is no longer operational, the mine was reactivated in the 19th century. The mine shaft and scrapheaps of the former copper mine can be still be seen to this day.
Particularly noteworthy are the small mineralisations of copper salts, especially malachite (a green mineral), and even rarer azurite (a blue mineral).

MINE GALLERY
The entrance to the gallery, which connected to the mine shaft, is now completely blocked. A tunnel was excavated into the hillside to divert the gully from the working area, that is, from where the ore was washed.

ODELEITE RESERVOIR
This reservoir spreads out over an area of 720 hectares. Water courses meander dramatically through the area, resulting in sinuous curves and abrupt escarpments. On the right bank of the old stream visitors will find a water mill, known as the "Moinho Novo" (New Mill), which is the reason for various paths coming together here.

CURRAL DA PEDRA (Stone Corral)
The location of an ancient necropolis, according to the locals. The area around Furnazinhas bears signs of other prehistoric necropolises linked to mining areas.

“CERRO PELADO” Trigonometrical Point
“Cerro Pelado” is the highest point in the area (231 m), and from here you can see Cumeada, the Odeleite Slopes, the Odeleite Reservoir and the lands that make up the Foupana drainage basin.

“CUMEADA” (Ridge)
A common term used to refer to a high, long ridge that forms a “backbone” between drainage basins.
