The history of the Mira de Aire Caves began relatively recently, in 1947, when they were discovered by chance by local residents. The discovery was prompted by a curious natural phenomenon: steam was rising from holes in the ground, resembling a boiling pot. Intrigued by this sight, the first brave explorers descended into the unknown on ropes, reaching a small gallery at a depth of about 20 meters. This marked the beginning of the exploration of one of Portugal's most impressive underground complexes.

Initial research was limited to the first gallery discovered. However, the researchers' persistence was rewarded: only two years later, they managed to find an extension of the vast cave system. News of this unique discovery spread quickly and reached Lisbon. Soon, the first speleologists arrived in the Fátima area, inspired by the idea of creating a scientific society to study these amazing caves, highlighting their importance from the very beginning.

Although the Mira de Aire Caves were found in 1947, they did not open their doors to the general public until much later—in August 1974. From that moment, their history as a popular tourist site began. In nearly half a century, by the end of 2022, more than 8 million people had visited these underground labyrinths, testifying to their enduring appeal and status as one of the country's primary natural attractions.

Exploring the Mira de Aire Caves typically takes about 1.5–2 hours. This time is usually sufficient to walk the entire tourist route without rushing, admire the beauty of the underground halls, examine the stunning stalactites and stalagmites, and take memorable photos.

The total duration of the visit usually includes not only the descent and the guided tour through the illuminated galleries but also the viewing of a short introductory film. This film tells the story of the caves' discovery and their geological features. Keep in mind that the route involves descending to a significant depth, so moving within the caves also takes some time. If you wish to linger in the souvenir shop or have a snack at the on-site cafe, you should allow extra time for that.

When planning a visit to the Mira de Aire Caves, be sure to check their current operating schedule. Although the caves are generally available to tourists year-round, opening hours may vary depending on the season or day of the week. To get the most accurate and up-to-date information, it is highly recommended to visit the official cave website or check details at tourist information points in the city of Fátima.

Additionally, it is a good idea to find out in advance if ticket reservations are required. During periods of high tourist activity or for group visits, this may be a mandatory requirement. Checking this information will help you plan your visit without unnecessary hassle and guarantee entry to this natural wonder of Portugal.

A visit to the Mira de Aire Caves is undoubtedly a highlight.
