Occupying the southern coast of Sri Lanka, Mirissa Beach is perhaps best known as a dolphin and a whale watching hotspot in the island nation. As a more tranquil beach paradise that's not as crowded or as congested as other southern beaches, the whale watching excursions in the area are conducted during the months of the year when blue whales and sperm whales are known to migrate across the Indian Ocean. Dubbed the Whale Watching Capital of Sri Lanka, those who wish to engage in this once in a lifetime excursion can sign up for an early morning tour conducted by the Sri Lanka navy or a private tour operator.
