Want an unforgettable experience?



Consistently over last several years, we have our first sighting for each season around June 10. Whales arrive from their long journey first at 'Eua Island and Tongatapu, before any of the other islands in the group. Increasingly over the years, whale numbers in these two islands show an increasing trend.

It is only April 2014 and our divers and fishermen are reporting hearing the singing of the whales in the ocean! Interesting to see what date will be our first whale sighting for 2014.

Whales travel up from Antartica so they arrive at 'Eua Island and Tongatapu first before any other islands in the Tonga group. Many whales stay in these two islands because of its calm and warm waters, and we note the numbers sighted at Tongatapu and ʻEua are increasing over the last 5 years. There are only 3 whale watching boats in Tongatapu and 2 boats in ʻEua Island. We believe less boats in the water, lower engine speeds and noise, means less disturbance, less threat for the whales, hence the increasing trend in Tongatapu and ʻEua Islands.

Our successful encounters are also due to the patience and expertise of our local crew. Once the whales are sighted, it may take an hour to two hours, to slowly follow at a safe distance. Then it gets to a point where our boat stops and allow the whales to initiate the encounter. This is the magical moment when these giants of the sea, turn around and check us out, with an invitation for us to enter the water and share the good news about their newborn baby calf. Its heartwarming that these giant creatures, trust us with the safety of their new born, by allowing them to playfully frolic with us

Nice weather and calm seas, play an important part in the success of the interactions. So book you tour but be flexible to change the dates during your time in Tonga, as good weather is key to the success of your encounter.


To enter the water, we divide guests into groups of 4 with a guide, on stand by at the back deck, to enter the water, at the direction of the captain. You will enter the water quietly, no splashing and follow your guide. You are not to go forward past your guide, and stay together so that the whales do not feel threatened by you splashing around and spreading out in different directions. If you see the whales in the water, raise your hand in the air so others can know. Cameras are permitted, so bring your Go Pros! to record these memorable moments.

Boat departs from Faua wharf Tongatapu at 10am, Monday to Saturday and returns around 3 to 4pm. Confirmed booking is a must, as its our high season, so you dont miss out. Sundays is our day of worship so no boat trips on Sunday.
