There is a secret cave and a blue lagoon in Portugal which is a true paradise to discover
Composed of the villages of Queiriga, Lousadela, Minas de Lagares and Quintas das Valas, the parish of Queiriga is 6km south of the county. It has an area of 35 km 2 between the left bank of the Paiva River and the right bank of the Vouga River. In the first half of the twentieth century maintained an intense mining activity.
The Queiriga mines, or Lagares mines, formed a mining operation in the 1940s, employing up to 500 workers, some of them foreign technicians, due to the shortage of qualified national labor.
Since then, Queiriga has undergone few changes, remaining the northern boundary of the village marked by houses once occupied by British, now converted into permanent dwelling places.
Access is not incredibly difficult but can be dangerous due to areas of potential slippage and above all the total lack of surveillance and proper facilities. And the amazing thing is that all this has ever existed there.
