Arta Caves are filled with limestone deposits, and they were opened for tourism in 1806 AD due to the splendor and rarity of this natural phenomenon, and guided tours are held inside them on a daily basis, as the duration of each tour is from 30 to 40 minutes, and guides are available speaking in four languages: Spanish, French, English and German, and at the beginning of The tour After passing through the main hall there is a room called the Queen of the Columns, where you can see stalagmites, which are about 22 meters high, which is certainly not a sight to see even in caves with other famous rock deposits, and it is also worth noting that the stairs at the entrance to the cave were built When Queen Elizabeth visited Mallorca for the second time.
