Top 20 Natural Monuments around Covilhã

Covão dos Conchos is an artificial lagoon located in the Serra da Estrela Natural Park, Portugal, near the mountain village of Sabugueiro. Covão dos Conchos became famous for its bell-mouth spillway[1]. The spillway was built in 1955 to allow water to be transferred from the Ribeira das Naves River to Lagoa Comprida. It is part of the Serra da Estrela Hydroelectric System. This science fiction-style spillway became famous when photographs of the hole went viral on social media in 2016. Over the past 60 years, the growth of vegetation at the funnel's mouth has created extraordinary biodiversity and increased its ethereal allure. It is 4.6 meters high and 48 meters in circumference. The tunnel that collects the water is 1,519 meters long.

Both Piódão and Foz d'Égua are accessible by car. But it's worth hiking the trail that connects them. It takes about 45 minutes, downhill from Piódão to Foz d'Égua (remember that the return is a slight climb). It's worth crossing the restored suspension bridge in Foz d'Égua before returning to Piódão. The Foz d'Égua pool is a popular spot for a dip in its very cold waters. Dipping your feet in the icy water of the stream is always very pleasant after a hike, immersing yourself in nature. I did it and recommend it. 👍🥾

A beautiful nature trail, about 9 km round trip to Covão dos Conchos. Unfortunately, on August 15th, the water couldn't reach the hole and thus reveal the waterfalls. It's a reservoir, part of the Serra da Estrela hydroelectric system. A funnel-shaped drainage structure that allows water to flow from this body of water to Lagoa Comprida. The spillway was built in 1955 to divert water from Ribeira das Naves to Lagoa Comprida. Over the past 60 years, moss and foliage have grown over the mouth of the funnel, creating a captivating spectacle. It is 4.6 meters high and 4.8 meters in circumference. The tunnel that collects the water is 1,519 meters long. It's a stunning place to visit, not only for the combination of human intervention and nature, but also for the surrounding landscape.

Located at an altitude of approximately 1,600 meters, Lagoa Comprida is the largest water reservoir in the Serra da Estrela, intended for hydroelectric generation. This natural lake lies in a wide depression of glacial origin, approximately one kilometer long, which fed the Covão Grande glacier. Numerous glacial scars are visible along its banks, making this lake one of the most interesting geomorphological sites in the Serra da Estrela. Construction on this lake began in 1911, and by 1914, it was already six meters high. Later, in 1965, it underwent heightening work that increased its height to 28 meters, currently boasting a storage capacity of approximately 14 cubic hectometers, flooding an area of approximately 80 hectares. Small streams of water flow into this lagoon, as well as water retained in the Covões dos Conchos and Covões do Meio and carried to this lagoon through underground tunnels.

The Serra da Estrela Natural Park is something truly special. This 1,000-square-kilometer park, spread across six municipalities, was the first and currently the largest protected natural park in Portugal. It is home to the highest point on the Portuguese mainland, the country's only ski slope, the source of two important rivers, and a fascinating, alpine-like landscape formed by glaciers.

At exactly 1993 meters above sea level, Torre is the highest point in mainland Portugal, where the only ski resort is located. The landscape on the upper plateau of the Serra da Estrela is like a sprinkling of granite rocks over low scrub and patches of snow and ice, which the sun threatens to melt soon in the summer and which always returns the following winter. In winter, it sometimes becomes inaccessible.

Nestled in the Açor mountains, near Piódão, the river beach of Foz d’Égua is an enchanted corner that comes alive in the summer. Where the Piódão and Chãs d’Égua streams meet, a natural pool is formed, surrounded by rustic bridges, old mills and shale everywhere.

At an altitude of 1,700 metres, in the heart of the Serra da Estrela, stands the impressive Nave da Mestra, a granite colossus that holds a centuries-old secret: the Barca Herminius. Built in 1910 by craftsmen from Manteigas, who climbed the mountain with mules and hydraulic jacks, this house nestled between rocks looks like something out of a fairy tale. It is said that it was designed as a summer retreat by the Matos Preto family, but the legend goes further: clandestine meetings against the regime, led by judge José Pereira de Matos, are said to have taken place there. That is why, to this day, it is called the Judge's House. Running along these trails is a real spectacle!
