Imagine standing before a mystical waterhole that appears like a doorway to another dimension.
In Portugal’s Serra da Estrela, Covão dos Conchos is a hidden marvel that looks like something from science fiction.
However, its wonder comes from human engineering, not magic.
Built in 1955, this waterhole serves a practical purpose as part of a hydroelectric dam project.
Covão dos Conchos was constructed to divert water from Ribeira das Naves to Lagoa Comprida.
Yet, what captivates visitors isn’t the functionality but the aesthetic beauty: a vortex-like spillway surrounded by moss-covered stones and natural waterfalls.
What makes Covão dos Conchos even more alluring is its remote location. To witness this hidden gem, you’ll need to hike through the Serra da Estrela Natural Park, home to Portugal’s highest mountain range.
Starting from Lagoa Comprida, the 8.9 km trail takes about two hours. While the hike is relatively flat, packing the right gear is essential, especially in winter when the lake can freeze.
This stunning spot remained a well-kept secret until recent drone footage revealed its magic.
At 4.6 meters high, with a 48-meter circumference, the man-made lake appears both artificial and entirely at one with its surroundings.
