The grand allure of Mirissa comes from the deep sea excursions offered. The large whales that swim through the currents of the Indian Ocean include blue whales, sperm whales and Bryde’s whales. It is a spectacle that can be viewed by anyone through a whale-watching excursion. You can also take your surfing board out to sea and ride the waves or enjoy exploring the world under the ocean’s surface through snorkelling or diving.
