The areas of the Indian Ocean close to the town of Galle have acquired a reputation as a good locality in which to spot whales. Blue whales, sperm whales and humpback whales, as well as dolphins, can all be spotted in these waters. The contracted continental shelf bordering the town of Galle permits whales to approach the shore whilst on their yearly migrations through the waters of the Indian Ocean. In fact, the ideal areas in which to observe these giant marine mammals are the ocean regions close to Dondra Point and Mirissa, both of these locations being in proximity to the town of Galle.
