More than 26 species of cetaceans such as blue whales, sperm whales, and fin whales can be observed from the Dondra Point (close to Galle, Hikkaduwa, Mirissa) and Trincomalee.
Dondra Point in the south is the most reliable place due to a ninety percent chance of seeing whales and a well-developed infrastructure. Trincomalee is located at northeast coast. Most of the whale-watching tours start at 6:30 am. Depending on the sea conditions, it can take about 3 hours. In the south, the best time for whale watching is from November to April. In the north, the best time is from July to September
