Ko Nu and Ko Maeo 

Perhaps the most well-known symbol of Songkhla province, both islands are located off the shore of Laem Samila. According to the legend, a dog, a cat, and a mouse, traveling on a Chinese sampan stole the merchant's magic crystal and tried unsuccessfully to swim ashore and drowned. The mouse and cat became the islands in the Songkhla Lake while the dog died on the shore and became the hill called Hin Khao Tang Kuan near the bay. Totally destroyed, the crystal then became the white sandy beach called Hat Sai Kaeo which literally means crystal sand beach.
