The ultimate destination for swimming with whales
Every year from July to November, humpbacks migrate to Tonga's warm waters to breed and give birth — and Vava'u is where the conditions all come together.
Legal & licensed
Tonga is one of the few places in the world where swimming with humpback whales is legal. Our knowledgeable, certified local guides lead every swim.
The most island protection in Tonga
Whale season is winter in Tonga — and that matters. Vava'u's islands offer the most protection in the kingdom from winter winds, so we head out on these crucial birthing and mating grounds almost every day.
Crystal-clear water
Vava'u's clear, blue waters are perfect for capturing unforgettable photos and video of these majestic creatures.
Tonga
Only 4 guests in the water at a time — a personal, uninterrupted encounter that also reduces stress on the whales, allowing more meaningful and respectful interactions.
French Polynesia
Whale swims often involve more than 10–15 swimmers around a single mother and calf — a far less intimate experience.
Safety, respect, and sustainability come first
The whales set the terms
Our experienced crew prioritizes the well-being of both the whales and our guests. We adhere to strict regulations to ensure encounters are respectful, non-invasive, and never disturb the whales' natural behavior.
Good for Tonga, good for whales
We are deeply committed to eco-tourism. By partnering with local businesses and communities, we support conservation efforts and have a positive impact on the environment and the local economy.
Fins, mask & snorkel only
Scuba diving with these fast-moving creatures is nearly impossible, so our whale swims are snorkel-only. Participants should have snorkeling experience — these tours involve a fair amount of swimming.
Consistent sightings, unforgettable encounters
We typically get in the water with whales almost every day — but it's the quality of those swims that really matters.
On average, the extraordinary whale swim days to expect on a 5-swim-day tour — with the other days still offering beautiful, memorable encounters.
A high-quality encounter lasts over 10 minutes with the whales in close proximity — an experience that will stay with you forever.
Tongan law allows each boat up to 7 hours of search and swim time daily — always with a licensed whale guide, and never more than 4 guests in the water.
