Ko Nu

Ko Nu, also known as Mouse Island, is a small uninhabited coastal island in Songkhla Bay off Samila Beach in Bo Yang, Mueang Songkhla, Songkhla Province. Paired with nearby Ko Maew (Cat Island), it is a well-known landmark and symbol of Songkhla. The rocky islet is best viewed from the mainland and is associated with a local folklore legend. It is not developed for tourism but is a popular photography subject.

Visitors can expect to view Ko Nu from Samila Beach and Laem Samila headland, about 1 km offshore. The island is small, rocky and uninhabited with sparse vegetation and no visitor facilities. There is no regular pier or landing point; most visitors observe it from the beach, viewpoints on Tang Kuan Hill, or on occasional boat trips that circle the island. The island is typically seen together with Ko Maew and the Golden Mermaid Statue on Samila Beach.

Ko Nu is linked to a well-known Songkhla folklore legend in which a cat, mouse and dog on a ship tried to steal a magic crystal and drowned, becoming Ko Maew, Ko Nu and Ko Nai Tang. The islands have long served as navigational markers at the mouth of Songkhla Lake and Songkhla Bay.

The paired islands Ko Nu and Ko Maew are cultural symbols of Songkhla Province, frequently depicted in local art, souvenirs and tourism promotion. The legend is part of local oral tradition and contributes to the identity of Samila Beach and the Golden Mermaid Statue area.
