The Devil's Horns are a prominent granite rock formation with two horn-like points, located in the Serra da Estrela mountain range, near Lapa dos Dinheiros and Senhora do Desterro (not in Gerês, but in Seia, Portugal). They are the highlight of a famous circular hiking trail that follows a water channel and the Caniça stream, offering stunning landscapes, lagoons, and waterfalls. 👍🥾

Cântaro Magro is one of the "commonplaces" of the Serra da Estrela mountain range, whose summit rises to 1928 m altitude, deserving a visit at any time of year. Viewed from west to east, its silhouette resembles a pitcher. In summer, its rocky face is interrupted by small terraces of soil, where some of the rarest botanical jewels of the mountain range grow. In winter, it is covered in snow and ice which, as they melt, form ephemeral waterfalls. These recall the overflowing liquid from the pitchers carried on the heads of women when, in the past, they went to the fountains. #CISE #VisitSeia #ParqueNaturaldaSerradaEstrela

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.

The Lapa dos Dinheiros river beach is in perfect harmony with nature. Located in the parish of Lapa dos Dinheiros, on the Caniça River, a right-bank tributary of the Alva River, this bathing area is nestled in a mountainous landscape dominated by the Lapa Souto (south of Lapa) and imposing granite outcrops. With clear water, very appealing for swimming, the beach boasts the award for accessible beach and has lifeguards and a bar available to visitors. The rugged terrain of the valley causes the river to form a succession of small waterfalls nearby. The Lapa Souto, in addition to its valuable collection of centuries-old chestnut trees, is also home to a high level of biodiversity. From the bridge, a pedestrian path leads to the Moura Hole and a viewpoint over the Caniça Waterfalls. The Buraco da Moura is a natural cave system created by the sliding and accumulation of large granite blocks, which formed a complex system of rooms and galleries. How to get there? Once in Seia, follow the EN231 to S. Romão. From there, continue uphill for about 5 km, toward Loriga/Lapa, until you find the sign for Lapa dos Dinheiros on the left. Once inside the town, simply follow the beach signs. Coordinates: 40º 23′ 07.0″ N / 7º 41′ 50.1″ W

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).

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. 👍🥾

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).

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.

The area around the Zêzere Glacier Valley, particularly Covão da Ametade, is a beautiful spot for relaxation and picnics, often considered a tranquil escape. Exploring the smaller waterfalls and river beaches beyond the main attractions can also reveal hidden gems.

What should I wear when visiting the natural monuments in Serra da Estrela?

Given the varied terrain and altitudes, it's advisable to wear good walking shoes, especially for trails with scree or uneven surfaces like the Covão dos Conchos Trail. Layers are recommended as weather conditions can change quickly, particularly at higher elevations like the Torre. In sunny weather, sun protection is essential as many trails offer little shade. If visiting in autumn or winter, waterproof clothing and warmer layers are crucial due to higher water levels and potential snow.

Another notable waterfall is the Fraga da Pena Waterfall, offering a picturesque natural setting.
