Get the chance to see whales and dolphins basking and cavorting in the Indian Ocean on a boat tour off the coast of Mirissa. The seas off southern Sri Lanka are absolutely brimming with marine life, which makes them perfect for spotting dolphins, blue, killer and sperm whales. After the cruise, you will also get to see locals stilt fishing and enjoy some free time at Unawatuna beach.

Head out on a trip to catch a glimpse of these huge creatures, known to dwell off southern Sri Lanka at this time of year. Keep an eye out for any spurts of water in the distance – a sign that one of the whales is near. You can even hear them a mile off, as their songs can reach almost 200 decibels – that's louder than a jumbo jet.

On the way back to port, you may encounter pods of dolphins racing with the boat, and once you're back on shore you may also see stilt fishermen at Unawatuna. After lunch, there's time to chill out on the beach or go for a dip.
