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. It is said this underwater water source also connects to the Nilavarai bottomless well which lies over 10km away from here. This spring is popular among the Hindus for the miraculous powers it holds.
