Why We Return to Tonga: Swimming with Whales the Right Way

August 28, 2025

Swimming alongside some of the oceans most iconic species will always be our favourite part of our work here at Blue Vagabonds. Respect for wildlife is at the heart of everything we do, which means we choose our locations, operators and conditions extremely carefully. We absolutely love returning to Tonga every year to swim alongside the majestic Humpback whales and believe that the strong regulations and high respect for the animals in the kingdom allow for meaningful interactions guided entirely by the animals. Born from mutual curiosity, not anything forced or intrusive.

Tonga’s Regulations

Swimming with humpback whales in Tonga is a privilege that few on our planet are lucky enough to experience. It is currently regulated to protect both humans and whales, ensuring the industry is set up successfully for generations to come.

Current regulations:

Staying on the surface: Tongan regulations strictly prohibit diving down or freediving with whales, but this doesn't diminish our encounters with these magnificent creatures. Since humpback whales are mammals that must surface to breathe, all interactions naturally occur at the water's surface. This ensures our encounters are entirely whale-led—the animals choose when and how long to spend time with us, creating authentic and respectful wildlife experiences
Small, controlled groups: To ensure the whales remain comfortable with our presence, only four swimmers plus one licensed local guide are permitted in the water at any time. These small group sizes create more intimate and meaningful encounters for everyone involved.
Time-limited encounters: Each encounter is limited to 90 minutes, assuming that the whale is comfortable and remains around the swimmers. After this time limit is reached, there must be at least a one-hour break before another group can approach the same whale.
Limited boat time: Operators can spend a maximum of seven hours per day on the water.
Minimum distance maintained: Swimmers must stay at least 5 meters from whales, and vessels must maintain a minimum 10-meter distance, except in emergencies.
Single-operator rule: Only licensed providers may engage in whale swims, and only one operator may approach a whale at a time. This is essential for keeping the animals comfortable and free from harassment.
Operational discretion: The captain or guide determines whether swimming is permitted based on the whales' behavior, with every decision prioritizing the animals' well-being above all else.

What the Regulations Mean for You on a Blue Vagabonds Adventure

We truly believe the most powerful and transformative encounters happen when respect comes first. These rules mean that the whales feel safe and are more likely to be curious on their own terms. Stress and behavioural disruptions are also kept to a minimum, which is especially important because of the high number of mothers and calves in Vava'u.

By supporting and encouraging countries like Tonga that establish thoughtful regulations for animal encounters, we contribute to a sustainable model that benefits everyone. When we prioritize whale comfort and respectful interactions, we help ensure long-term positive encounters that sustain a responsible tourism industry, one that sets an example for the world.

Regulations in Vava'u also ensure that your experience is as authentic and memorable as possible, not a forced photo opportunity or a frantic scramble to get close to a fleeing whale. We know that when respect leads the way, the whales often return that trust tenfold. Tonga offers a rare opportunity to share the water with one of nature's most awe-inspiring creatures. At Blue Vagabonds we remain committed to bringing ocean lovers to wildlife in a respectful, safe and sustainable way.
