Mirissa is a crescent-shaped bay fringed with coconut palms and lapped by the warm waters of the Indian Ocean. By day, the beach invites leisurely swimming, snorkelling and sunbathing; by night, its collection of open-air restaurants and beach bars creates a convivial atmosphere. Mirissa is also Sri Lanka’s premier whale watching port, with boat tours operating between November and April offering spectacular encounters with blue whales -the largest animals on Earth.
