Swimming with Humpback whales in Tonga

Snorkeling with Gentle Giants in Tonga

The Kingdom of Tonga is a hidden gem in the South Pacific. A lush group of islands surrounded by vibrant coral reefs and crystal-clear waters. From July to October, humpback whales visit the calm, protective waters of the Vava’u archipelago to mate and give birth. This natural migration allows us to observe the whales in their natural home.

Snorkeling with Humpback Whales in Tonga

Our land-based expedition offers you the unique opportunity to go snorkeling with humpback whales. Expert guides will take you out for daily snorkeling trips to have the most incredible whale encounters. Humpback whales are curious creatures, and even though they are the giants of our oceans, underwater encounters are usually very gentle. While snorkeling with the whales, you will witness the bond between mother and calf and their unique behaviour. The curious calves explore their environment and seek out interactions with the new world they have entered.

Responsible Whale Expeditions

Tonga is one of only a few places in the world where you can swim with humpback whales. Whale swimming is a carefully regulated activity with specific rules in place to protect the animals and ensure a safe and respectful experience. Only 4 people and a guide can be in the water with the whales at any one time. We believe it’s a privilege to swim with whales and practice a soft approach to interactions with these amazing mammals. The encounters can last 1 minute or 1 hour, depending on how comfortable the whales are, but expect to get up close and personal with them at some stage on your trip.

Expert Tour Guides

A team of award-winning photographers and professional marine biologists will be the tour leaders during your whale snorkeling expedition. They will share their experiences and knowledge about the humpback whale, and take you to the best secret spots around the islands. The time we spend snorkeling depends on the whales, weather and location. There are endless snorkeling spots to try and we attempt to stay out on the water for approximately 7 hours per day.

Sample itinerary

These land-based expeditions include 7 nights in premium (shared) accommodation on the island Vava’u, during which you will have 5 days in the water. Groups consist of only 6 people in order to maximise your time in the water with the whales. On snorkeling days, we usually embark around 7:30am for a full day of swimming with humpback whales and exploring the coral gardens, impressive caves and abundant marine life that Tonga has to offer.

This itinerary is an example, and things change often when you are on an Island in Tonga. The locals are on what we call ‘Tonga Time’, so don’t be  disappointed if the skipper is late, or your meals are not served on time, just relax and enjoy this tropical paradise.

Day 1 | Arrival to Vava'u, Tonga

Once you arrive to the island of Vava’u, the driver will be waiting for you at the airport and will take you to your accommodation. Your guides will meet you for dinner and organise a briefing about the upcoming tour.

DAY 2 - 4 | Swimming with Whales & Snorkeling

Around 7.30am you will be picked up from your resort for a full day of swimming with humpback whales. We use a small boat with easy access into the water. The Vava’u islands provide an ideal nursing ground for the humpback whales. We’re likely to encounter mothers with their calves, and the boisterous males are never far away. You might even be lucky enough to see a large groups of males on a heat run. We go snorkeling with those whales we think will be approachable and interactive. Lunch depends on the whales and afterwards we try to stop in a number of snorkeling spots each day. Around 4pm, you will return to your accommodation.

DAY 5 | Leisure day

Sundays are a time for rest in Tonga and most places are closed except for some cafes and restaurants. It’s a good moment to relax, go for a stroll or take a nap on the beach.

DAY 6 - 7 | Swimming with Whales & Snorkeling

More whale swimming today, and a chance to experience some of the varieties of whale behaviour found in Tonga. You might encounter curious humpback calves, or the eery beauty of a singing male. In the afternoon, we might visit the legendary Swallow’s cave, or Mariners cave for some more exceptional snorkeling.

You will get to visit some of the most pristine snorkeling spots around Tonga, including untouched coral reefs, lagoons and caves. But if you haven’t had enough after your days on the water, there are lots of other activities to enjoy. Spend a few more days exploring the islands, snorkeling, diving, quad bike riding or just relaxing on a beach. There is plenty to do on land and in the water!

DAY 8 | Departure

Checkout is at 10am. The driver will be waiting for you at your accommodation to take you to the airport.

Flights are not always reliable and it’s best to give yourself a buffer day before and after your trip. When flying interisland, flight times may be changed without notification, so make sure to check regularly with the airline.

FAQ

We suggest bringing your own mask, snorkel and fins as it’s easier to use the gear you are familiar with. Below is a basic packing list of items to bring with you:

  • Sunblock 30+ (ideally reef-friendly)
  • Sun glasses
  • Wetsuit – mainly for buoyancy as the water temperature is about 25°C. We recommend a 3mm wetsuit.
  • Mask, fins, snorkel
  • Camera or action cam
  • Swim suit / bikini
  • Sun hat / cap
  • Beach Towel (mainly for the boat)
  • Spray jacket/Windproof jacket
  • Summer attire (shorts, T-Shirts, sandals, etc.)
  • Bug spray
  • Basic medical supplies

You’ll be out on the water for approximately 7 hours per day. However, the time depends on the whales, weather and location. There are numerous snorkeling spots that we will try and stop at each day during lunch.

Please note, by law 7 hours is the maximum time on the water whale watching.

Swimming with the humpbacks is limited by regulations to snorkeling. The whales often stay close to the shallows or on the surface of the water, so there is no need to dive. If you would like to scuba dive in other locations around the islands, this can be arranged with the local dive operator.

Tonga is tropical so it’s usually quite hot during the day, although there can be wind or sometimes rain. Average temperatures range between 20°C and 28°C (July – October). Temperature varies at night, it can be quite humid, but generally it’s cool in the evenings, around 20°C. The sea in Tonga is warm all year round, usually between 24°C and 27°C.

It rains mainly in the night, but rain does not stop us from going out. We are on the water all the time, no matter what conditions, and weather is rarely a problem.

If you're interested in adventure travel, you simply will not find a better, more knowledgeable, experienced, and whale-centered crew than with Waterproof. As repeat customers, 10/10 would recommend Waterproof and we will continue to return to this area of the world as their customers.

My wife and I can't thank the team at Waterproof Expeditions enough for an incredible trip to Norway to swim with orcas. The booking was easy and straightforward, and we were taken care of from the minute we met our guides in Tromso. The ship is comfortable with plenty of spaces to hang out and stay warm, a hot tub, sauna, and hot water available for coffee and tea.

We had an absolutely amazing trip in Svalbard. The communication with Waterproof was at all times very friendly, punctual and correct. We would highly recommend booking trips with them and especially onboard the Plancius.

Petra

It was my dream for many years to see Orcas. With Waterproof Expeditions it was so much more than that. The weather was challenging but Rinie and Szymon where the best guides and hosts for this trip I could imagine. I would highly recommend the trip to whale lovers, nature enthusiasts, adventurers and whoever is looking for memories of a lifetime. Everyone on our trip was fantastic, also the other guests which made the journey even better.

Sabrina

Winter Whales of Norway 2024
We participated in the Winter Whales of Norway expedition aboard the Polarfront in November 2024 and it was one of the most incredible experiences we have had. Like with all wildlife and nature expeditions, we came into the trip nervous about whether the whales and orcas would be present and whether the weather would cooperate. The trip ended up vastly exceeding our expectations!

Winter Whales of Norway- Nov 2024
This was the best trip I have literally ever taken. If you are looking for an expedition that put whales front and center, while also truly caring about the ecosystem and simultaneously your needs are being taken care of, then do not hesitate to book!

We all had a wonderful time last summer and I cannot rate highly enough the entire experience: the ship and crew were exceptional and with Rinie's expert help, we had fantastic polar bear sightings.

We have been on many wonderful trips, but this one is certainly one of the finest. The Orcas and whales, the ospreys and the magnificent scenery left an unforgettable impression. The icing on the cake were the northern lights. The guides were also of champions league level. The captain and his crew did their utmost to spoil us. Thanks for organizing this trip very professionally.

We went on a Norway cruise with Waterproof Expeditions. It absolutely exceeded our expectations. Orca’s, Humpbacks (from the boat as well in the water), northern lights, beautiful scenery. It was an amazing experience thanks to the professional care of our guides and crew on the boat. Absolutely recommended to choose this organization to make a trip.
