Aside from being a paradise for rock climbing activities, there’s actually a legend behind Phranang Cave.
One of the legends goes like this - a very long time ago, there lived a very beautiful maiden in a castle in this land. Because of her infectious beauty, she was the object of many local men’s affection. However, she refused to return their love. One day, a young man from Hua Kwan Island (currently known as Chicken Island) proposed to her but she refused. The young man tried to take her away with him by force, but another young man from Naga Island suddenly appeared and helped the beautiful maiden. In turn, she agreed to marry him.
On the wedding day, as the young man arrived with traditional dowry, a group of men who were angered by the news of the marriage came to pick a fight with him. The fight was so violent that a hermit living in a nearby cave came out and attempted to put a stop to it. Naturally, nobody listened to him. Left with no other options, the hermit used magic to transform the scene into stone. The maiden became Phranang Cave. The groom-to-be became Chicken Island. Other men turned into Poda Island, Horn Nak Island and Hang Nak Island. The tray carrying the dowry sank into the sea and became Happy Island in front of Phranang Beach. The sticky rice for the feast became Fossil Shell Beach.
