Places to see sea turtles
The south and south-western coast of Sri Lanka is pretty much one long palmy beach. These white stretches of sand are nesting grounds for a range of sea turtles, mostly Green turtle, Olive Ridley, and Hawksbill, but also Loggerhead and the rare Leatherback. During peak nesting season (December to March) you have a pretty good chance to bump into the turtles that are patrolling the shore. Though they are super cute, please give these amazing creatures some space and discourage any trade with their shells (or any other part) - yes, locals still sell them and moron tourists still buy them.
