Centrally located in the park and easily accessible via a beautiful, paved road is the Torre. This is the highest point of the Serra da Estrela mountain range; nowhere in continental Portugal can you go higher. Actually, the highest point is at 1,993 meters. A small tower of 7 meters on top of the mountain completes the 2,000 meters.

A fantastic and very isolated climb from São Romão. At the time I passed, the road was closed to motorized vehicles due to works in the lower area, which ensured a climb with zero cars and total communion with nature.

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.

Sabugueiro, the village vying for the title of highest in Portugal, is also one of the most authentic ambassadors of mountain life. Among granite houses and comforting flavors (cheese, sausages, roast kid, and honey), you can find the warmth of blankets and burel coats and the company of the faithful Serra da Estrela mountain dogs. Surrounding waterfalls, streams, and lakes remind you that here, nature is as generous as the table.

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.

This reservoir, part of the Serra da Estrela hydroelectric system, is a popular tourist destination. Part of this attraction comes from 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. The conical spillway was little known until photos of the hole went viral in 2016. 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 is a stunning place to visit, not only for the combination of human intervention on nature, but also for the surrounding landscape. The trail from Lagoa Comprida leads here is truly beautiful in any season. Bring windbreaker and water.
