Swim with the Humpbacks

These are wild animals, so nothing is ever guaranteed, but humpbacks are remarkably calm and deliberate around people when they are approached with patience and respect. We always enter the water on the whales' terms, never crowding or chasing them, and we follow strict government regulations the entire time. What keeps everyone safe is simple: listen to the captain and whale guides. Their word is final, and following it is the single most important thing you can do.

You should be a confident, comfortable swimmer and at ease snorkeling with a mask and fins. We spend long stretches at sea each day, you will be entering and exiting the boat repeatedly, and the ocean can range from flat calm to a real swell. You don't need to be an athlete, but the more time you can spend in open water before the trip, the more you'll enjoy it. Every water activity is optional, so you can always sit one out.

This is an active, ocean-based trip with full days on the water, so you should be in good general health and able to get in and out of a boat without difficulty. If you have any medical conditions or injuries, please let us know in advance so we can plan accordingly. Tonga is remote and access to advanced medical care is limited, which is why medical and evacuation insurance is required (see below).

It varies completely with the animal and the day. Adult humpbacks are aware of their size and usually hold a respectful distance, though a curious one may glide surprisingly near. Calves are the wild cards: they're playful and still learning their boundaries, and a calf may swim right up to study you. Whatever happens, we hold our position and let the whale decide how close the encounter becomes.

No two days are alike. Over a week on the water you might see resting mothers with their calves, singing males suspended head-down in the blue, energetic young whales, heat runs (groups of males competing), and sometimes dolphins or pilot whales passing through. Each whale has its own temperament, so every encounter is genuinely one of a kind.

It is, and that is non-negotiable for us. Tonga regulates these encounters carefully, we keep our in-water groups small, and we never touch the animals or pursue one that wants to be left alone. If a whale signals that it's done, we back off. The goal is always a quiet, low-impact encounter where the whale stays comfortable and in control.

No. We snorkel and freedive at the surface with the whales, so no certification is needed. Scuba isn't used during whale encounters, both because it isn't necessary and because the bubbles can disturb the animals. All you need to bring is your own mask, snorkel, and fins.

Bring your own mask, snorkel, and fins, plus reef-safe sunscreen and a dry bag. A wetsuit or rash guard isn't required but is worth considering, since even pleasant water temperatures pull heat out of you over long swims and a layer helps with sun, too. The full packing list is above, and we're glad to talk through gear once you've booked.

This is an expedition built around the experience itself, not a photo workshop, and the whale's comfort always comes first. You're very welcome to bring your own underwater camera or GoPro, and a few tips for capturing the moment are in the Photography section above. We just never chase a shot at the animals' expense; the best memories usually come from simply being present.

This expedition is designed for adults and capable swimmers. If you'd like to bring a younger family member, please reach out to us beforehand so we can talk through whether it's a good fit for them and for the group.

Yes. Because Tonga is remote with limited medical facilities, you are required to carry medical insurance that covers treatment and emergency evacuation, and we strongly recommend trip-cancellation coverage as well. We don't endorse any particular provider, so please research and choose the coverage that's right for you.
