Antiparos Cave is a popular tourist destination which is known for its stunning natural formations, including stalactites and stalagmites. 

Visitors to the cave can take a guided tour, during which they will see the immense stalagmite at the entrance that is believed to be the oldest in Europe dating back up to 45 million years, and descend 411 steps to the main chamber, which is over 100 meters deep. 

In addition to its natural beauty, Antiparos Cave also has historical significance, as it was used as a place of worship during ancient times.
