Papafragas is a must visit beach of Milos island. In fact it is a sea cave, which was used in the past as a pirate base. The beach got its name from the franc Priest who used the cave to moor his boat. You can walk down to the beach using the stairs, however with great caution. Swim into the cave and exit it on the other side if you want to see the nearby beaches. The water is turquoise and crystal clear inside the cave. We recommend you to swim at the beach just before the cave of Papafragas and the parking lot (before turning to the house on the left). Next to the sea cave is the archaeological site of the ancient city of Phylakopi, which you can visit before your morning swim when it is definitely open.
