Adam's Rock is a protrusion in an abrasion platform, a remnant of an ancient kurkar ridge.

The nature researcher and tour guide Yehuda Ziv wrote about the island: The southernmost of Jaffa's reefs, opposite the beach of Bat Yam, is known in Arabic as 'Hajar Adam' – Adam's Rock.

The legend tells us that the fish in the Mediterranean come here in bands, kiss the rock, and continue on their way...

The island was swallowed up among the large stone boulders that were piled up in front of Bat Yam's seashore to protect its beach, barely visible from the promenade".

[2]The legend and name were previously mentioned by Zev Vilnay, who dates these back to the Middle Ages.
