Keerimalai is a natural spring lying next to the sea west of Palaly. A bathing tank is built surrounding this pool and only the walls separate the waters of the spring and the sea. Although the tank is so close to the sea, the water is fresh coming from an underground fresh water spring in Tellipallai-Maviddapuram. The water is not hot. This spring is popular among the Hindus for the miraculous powers it holds.

According to Local folklore a pandiyan Princess named Maruthapura Veeravalli built the Hindu Kovil at Keerimalai when she was cured of her horse shaped head after bathing at Keerimalai.
