What Travellers Say
Reviews Summary
Visitors consistently praise the Grutas de Mira de Aire as a magnificent natural wonder, highlighting the stunning geological formations and the unique experience of exploring underground. The presence of dinosaur footprints and the helpful guide app are often mentioned as positives. However, some find the large group sizes and language barriers during tours can detract from the experience, and transportation logistics, especially on Sundays, can be challenging.
"About a month ago, we decided to make a side trip from Fatima to Grutas de Mira de Aire on a Sunday. Getting there was easy enough via Bolt.
The tour starts with an introductory video in Portuguese, with English subtitles available. There is a handy app that can be downloaded and functions as a guide to the various sights in the cave. It works even without internet access.
The cave complex is magnificent and it was a unique experience being about 100m underground in a vast chamber, surrounded by all sorts of stalactites and stalagmites. There's even an underground river if you have had enough of looking at rocks.
Getting back to Fatima, though, was difficult. There was no Uber or Bolt available, and there is no public transport on a Sunday. We were very fortunate to have a staff member, Lara, who was extremely patient and helpful with us, non-Portuguese speaking folk, and she managed to arrange for a taxi to take us back to Fatima."

"Amazing, worth the price and the journey to get there. Third time there and with no regrets. The staff is very friendly and funny, the guide says a lot of jokes on they way down the caves, but only in Portuguese language of course.
There's cafeteria, restaurant, gift shop and plenty of parking around."
Elisabete Filipe
"The cave was beautiful and glad we went during the low peak season. Our tour went quicker than others stated. One thing to note: each section of the cave has their lights on a timer system so, if you lag behind it will turn off (the path lights remain on).
So, be cautious with your footing."
