However Merong Mahawangsa was eventually defeated by Garuda and he had to flee, reached the nearest land and founded his own Kingdom Langkasuka, which is the modern day Kedah of Malaysia. This mythological story is known as 'Battle of Big Birds'. 
The cave sits on sea water. There are two caves here, one on top of the other and both facing the sea. With the help of an wooden ladder, you can access the caves. Every year, many tourists take boat rides to visit the cave. 
Another legend says that a giantess called Gadembi visited the cave thousands of years back. She had the supernatural power of turning anyone and anything into an ox. The moment she saw the cave, she liked it so much that she wanted to live here. But the existing inhabitants of the cave refused to vacate it. Gadembi then used her power and turned all of them into stones. Locals say that there were various stone formations that could be once seen here that resembled the inhabitants of the caves. But they no longer exist. 
Other than many strange stone formations that still exist, you will also see many amazing stalactites and stalagmite formations in both the caves. 
There are old Arabic script inscriptions on the walls of the lower chamber of the caves. They are hardly visible these days. But they do exist. It is anticipated that some of the scripts relate to the verses of Koran and some relate to Sheikh Baharuddin. They are believed to be written in the year 1754 during the time of Sultan Mohamed Jiwa II of Kedah.
