The deep water off Dondra Head, Sri Lanka’s southernmost point, is one of the most reliable places in the world to see blue whales. Boats leave Mirissa harbour at dawn in season and spend three to four hours at sea, looking for blows on the horizon.
Sightings are good but never guaranteed, and the sea can be rough. Choose an operator that keeps a respectful distance from the whales, and go as early in the season and the day as you can.
Top things to do: Whale Watching
Take a morning boat from Mirissa
Most boats leave between 6 and 7 am and return around midday. Breakfast is usually included. See our ranked whale trips.
Book a trip with transfers
Several tours collect you from your hotel, which avoids hunting for a tuk-tuk before sunrise.
Look for dolphins and turtles too
Large pods of spinner dolphins are common, and sea turtles are often seen near the harbour.
How to get there from Ahangama
- Boats leave from Mirissa harbour, about 30 minutes east of Ahangama. Allow time for check-in before departure.
- Tours with transfers pick up from hotels along the coast.
Insider tips
- Take seasickness tablets an hour before you board, and sit on deck near the back.
- Bring a hat, sunscreen, water and a light jacket for the early start.
- Outside the season (May to October) the sea is rough and few boats run here.
- Choose an operator that keeps its distance; chasing whales is bad for them and illegal.
