Ahangama is about 30 minutes away from Mirissa, and Mirissa has some of the most excellent vantage points from where you can see whales. Orcas, turtles, dolphins, flying fish, manta rays, and the blue whale, which is the world's biggest mammal, can all be seen off this coast. Make sure to schedule your trip between the months of November and April, as they are more visible during this period.
