Grutas de Mira de Aire

Grutas de Mira de Aire is a natural cave system created through limestone, featuring underground lakes, pools, and sculptural rock formations at different depths. The caverns display a complex network of passages and chambers that reveal the slow work of water through stone over long periods of time.

The caves were discovered in 1947 when local people noticed steam emerging from a rock opening while searching for water in the area. This chance encounter sparked systematic exploration that revealed the full extent of the underground system.

The caves have become a source of local identity and pride since their discovery, symbolizing the natural treasures hidden beneath the landscape. People from the region and beyond view them as part of Portugal's geological heritage.

Visits are guided along marked paths with descending steps, while elevators return visitors to the surface more easily. Wear sturdy shoes and bring a light jacket, as the caves are cool underground and floors can be slippery.

Wine is aged in one of the galleries using the cave's constant cool temperature, taking advantage of the natural environment for storage. This creative practice demonstrates how the underground space supports activities beyond simple tourism.
