Swimming with Whales for Beginners: An Honest Guide

Nothing fully prepares you for the moment the engine cuts and the guide signals that it is time to get in. The shift from watching to being part of it happens fast. One moment you are looking at the horizon. The next you are floating in open ocean, aware that somewhere below you is one of the largest animals in the sea.

So, can a beginner swim with whales? Yes, in a few places where it is legal and regulated, with Tonga, French Polynesia and Réunion the best known, as long as you are comfortable floating in deep water and you follow a licensed guide. Most beginners feel excitement and nerves at the same time while they wait, and that is completely normal. Swimming with whales is not about control or performance. It is about being present in a world that moves at its own pace, not yours. And let me say it plainly: nothing here is guaranteed. Whales are wild animals in open water. Some days they come close. Other days you spend an hour in blue water with nothing but anticipation, and both are part of the experience.

Why swimming with whales feels different from other wildlife encounters

On land, wildlife encounters usually happen at a distance. In the ocean, everything is closer and more immersive. Sound travels differently underwater, and you can sometimes see much further than you expect.

When a whale passes nearby, size stops being an idea and becomes something you feel in your body. Many swimmers say the moment feels calming more than overwhelming. Whales on their breeding grounds often move at an even, unhurried pace, and that rhythm tends to shape the whole encounter: your attention leaves the boat and settles into the present.

Our advice for beginners is simple: stay calm, keep your movements slow, and let the curiosity come from the whale, not from you. Presence, more than any swimming skill, is what makes the encounter work.

Where can beginners swim with whales responsibly?

Where you go shapes the whole experience. Some places have calmer conditions and clearer rules, which helps first-timers feel supported. Here is what we could confirm, and what we could not.

Tonga is known for humpback mothers and calves, with peak season for boat and swim tours from July to October, according to the International Whaling Commission's Whale Watching Handbook. It is also one of the more tightly regulated places to do this. Under Tonga's Whale Watching and Swimming Regulations of 2013, only licensed operators may offer in-water activities; only four clients and one trained guide per boat may be in the water with a pod at a time; only one licensed vessel at a time may put swimmers in with a given pod; and time with a pod that includes a mother and calf is limited to about one and a half hours. Sources disagree on the length of the break after that, and the IWC notes the regulations are under review, so check the current rule before you travel.

Moʻorea, French Polynesia, sees humpbacks generally from late July to early November. The rules are in the French Polynesia Environment Code (articles A. 2213-1-4 to A. 2213-1-11), and the territory's Direction de l'environnement summarises them like this: nobody may enter a 15-metre safety zone around the animal, no boat may enter a 100-metre exclusion zone, and only three authorised boats may be inside the 300-metre observation zone, at under 3 knots. Swimmers enter the water only from an authorised boat, outside the 100-metre zone, and at most 7 people per boat, guide included. Whale watching is forbidden in lagoons, bays and passes. Rules are reviewed often, so ask your licensed operator for the current version. If you are weighing it against other places, our comparison of Moʻorea, Tonga and Réunion goes deeper.

Réunion Island deserves an honest word. It is one of the rare places that allows swimmers in the water with humpbacks, including mothers and calves, but the rules have tightened. After a difficult 2024 season, a new prefectoral order for the 2025 season (1 July to 30 September) reduced the number of boats allowed within 300 metres of an animal from five to three, cut the number of people allowed in the water from ten to seven, and limited water entries to between 09:00 and 13:00. Officials pointed to whales showing more and more avoidance behaviour around observers. Watching from the shore on the island's west coast remains the lowest-impact option, and for a first season it is a truly rewarding way in, without the pressure of a swim.

Rules like these change as research and local management change, so wherever you go, trust your licensed local guide more than a number you read in advance.

Getting ready for your first encounter

Preparation builds confidence, especially if open water is new to you. You do not need to be an athlete, but feeling at ease floating in deep water makes a real difference to how much you enjoy it. Operators in Moʻorea, for example, say you need to be able to swim in the open blue.

The right equipment helps with movement and warmth. A low-volume mask and snorkel that seals comfortably without pressing on your face makes floating much easier. A wetsuit or rash guard suited to the water temperature keeps you warm and covered. Longer freediving-style fins let you kick smoothly with less splashing. And a mineral sunscreen, used sparingly while covering clothes do most of the work, keeps what you leave in the water to a minimum.

It is also worth practising your finning before you travel. Long, slow kicks save energy and disturb the surface less, which is kinder to the whale and calmer for you.

Getting into the water quietly, without splashing, matters. Your guide will brief you in detail first, and that briefing is for the whale's comfort as much as yours, so listen closely.

Understanding whale behaviour eases the nerves

Much of the nervousness beginners feel comes from not knowing what a whale's movements mean.

Humpback whales can be curious, but they are wild, and they decide. A sudden movement or an attempt to swim toward them is more likely to make a whale move away than come closer. Staying still lets the whale set the terms.

Surface behaviours like breaching or tail slapping are not aimed at swimmers. Researchers link them to communication, social behaviour and other reasons still being studied. Once you know that, a breach in the distance becomes something to enjoy, not something to fear.

The ethical layer: sometimes the kindest choice is staying on the boat

Swimming with whales is a privilege, not a right, and it only stays possible where it is well managed. The places that allow it all limit the number of boats, the number of swimmers and the time spent with each group of whales, especially mothers and calves, who are resting and nursing in these warm waters. When a whale is moving away, resting near the surface with a calf, or there are already too many boats, a good guide will say "not this one". That is the guide doing the job well, not failing you. Wildlife encounters are unpredictable. Swimming with whales should always follow local regulations and experienced professional guidance.

It is also honest to say that reaching Tonga, Moʻorea or Réunion usually means long-haul flights, with a real environmental cost. We think the fairest answer is to go less often, stay longer, and choose operators who respect the rules even when nobody is checking. And where the rules are unclear, or swimming is not legal, we do not swim. Watching from the boat or the shore is a complete experience in itself.

From anticipation to presence

Many first-time swimmers notice their nerves fade once their attention moves to breathing and watching. The wait before getting in is often more intense than the encounter itself.

The quiet moments tend to be the ones people remember most. With no engine noise and no conversation, the encounter can feel completely immersive without ever feeling too much.

Whales move on their own schedule, and the best thing a swimmer can do is follow that rhythm instead of trying to direct it. For many people, the change in perspective lasts longer than the trip. Whatever felt urgent on land can feel a little smaller after an hour near something so much bigger than the everyday.

If this made you curious, our Moʻorea retreat in September 2027 is a small hosted trip in September, inside the humpback season, from CHF 4,500 per person in a double room shared with your own partner or friend. You can book by messaging Rocío, and you can see all our retreats here.
