In search of the most distant possible destination? What about a trip to the Earth’s core? It is possible that Covão dos Conchos will lead you there.

Lagoa da Serra da Estrela, a magical waterhole in Portugal, like a set from a science fiction film.

The enormous hole is not a gateway to another world; your imagination is playing tricks on you. Engineering, not magic, is responsible for its mystical properties.

Built in 1955 as part of the adjacent hydroelectric plant, Covão dos Conchos is a man-made lake. By collecting water from Ribeira das Naves and directing it to the Bayou Lagoon Long, the lake’s vortex-like spillway supplies fresh water to the surrounding neighborhoods.

Drone footage of Covão dos Conchos was shared online after it had been kept hidden for a long time.

Its circumference is 48 meters, and its height is 4.6 meters. A staggering 1519 meters long is the tube that catches the water.

Moss grows around the aperture of the man-made spillway, creating the illusion of cascading waterfalls, making it blend in with its natural surroundings.

How to get there: Covão dos Conchos is situated in the natural park of Serra da Estrela, which is inhabited by the tallest mountain range in Portugal.

Hiking is the only way to reach the man-made wonder because of how far away it is from any major city.

The 8.9-kilometer trip begins at the Lagoa Comprida parking park. Approximately two hours is required for the entire trip, and it is flat and easy to follow. This is the complete trail.

Even if you’re planning a winter trip (the lake might ice), be sure to bring warm clothing and sturdy footwear.
