Mirissa is a small, crescent-shaped bay on Sri Lanka’s south coast that has evolved from a quiet fishing village into one of the island’s most beloved beach destinations. It is internationally renowned as one of the best places in the world to watch blue whales and sperm whales in their natural habitat, with boat excursions running from November to April. The beach itself is a wide, gentle arc of golden sand ideal for swimming, and the town is dotted with excellent restaurants, beach bars and surf spots.
