The seas off Mirissa are absolutely brimming with whales and dolphins – and this cruise offers you the chance to see them basking and cavorting in the Indian Ocean. As well as dolphins, blue, killer and sperm whales can be spotted off southern Sri Lanka. You'll also see stilt fishermen and have free time on Unawatuna beach.

You'll head out on a trip to catch a glimpse of these huge creatures, known to take residence 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. And you can 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 might encounter pods of dolphins racing with the boat. And once you're back on shore you'll see locals stilt fishing at Unawatuna. After lunch, there's time to chill out – relax on the beach or go for a dip.
