Each year, from July through October, the waters surrounding Tonga transform into one of the most extraordinary natural playgrounds on earth. Humpback whales migrate from Antarctica to these warm, protected lagoons to give birth, nurture their young, and rest in the tropical calm of the South Pacific. It’s here, in the turquoise shallows around Mount Island, that you’ll experience one of life’s rarest privileges swimming alongside these gentle giants in their natural environment. Our exclusive 7-day itinerary blends intimate whale encounters with the serenity of island life, gourmet dining, and barefoot luxury. While itineraries may shift slightly based on arrival days and ocean conditions, Sundays are always reserved for rest, reflection, and soaking up the beauty of this sacred island sanctuary.

Touch down in the breathtaking islands of Vava’u, where your Tongan adventure begins. After clearing customs and immigration, our friendly Mounu Island team will be waiting to greet you and assist with a seamless transfer to the marina. From there, you’ll board a private boat for a scenic 25-minute ride across turquoise waters to your island retreat. A warm welcome, refreshing lunch, and brief orientation await your arrival. The rest of the afternoon is yours to unwind, settle into your beachfront bungalow, and take in the beauty of Mounu — your home for the week ahead.

Sundays are a day of rest in Tonga. Spend the day unwinding on the island — snorkel off the beach, read a book in a hammock, or join an optional boat ride to town if you’d like to attend church or explore (please note, most shops are closed).

Enjoy breakfast before your return journey to Vava’u Airport. A short 25-minute boat ride and transfer will bring you to the airport with plenty of time to check in. As you depart, it’s never goodbye, just a warm “see you later.”
