📍 Secret Islands, Tonga
Join us on a secret archipelago in Tonga and swim with gentle giants for the experience of a lifetime!
Having travelled all over the world in search of the most unique marine interactions, we are proud to share what might just be our best adventure expedition so far… After multiple recces, we have found an incredibly quiet island paradise where there is very limited tourism and only a handful of boats in the water.
Disconnect from the hustle, the bustle, and reconnect with yourself as you glide beneath the waves in search of truly awe inspiring marine interactions.
The very special secret islands where we are based is one of the most untouched whale destinations in the world and whilst Tonga IS popular as a whale swimming destination, few travellers make it to this remote corner of the archipelago.
Every year, humpback whales gather to give birth, nurse their calves, and socialize in warm tropical waters after migrating thousands of miles from Antarctica.
Unlike many other places where boats crowd around animals, this region remains remarkably quiet. Only a small number of boats operate across the entire island chain, meaning most encounters happen without other vessels nearby or even in sight! This creates calm whale-initiated interactions run with respect by our talented crew.
Witness mothers and calves resting gently together on the seafloor, curious juveniles approaching swimmers slowly from the deep, and sometimes males competing nearby with breaching and tail slapping activity.
With a hydrophone onboard, we can also listen to the haunting songs of humpback whales echoing through the ocean, a unique way to feel closer to these ancient beings.
Beyond whales, the waters of Tonga are alive with marine life. You can see dolphins playfully riding the bow of the boat, manta rays gliding beneath the surface, and false killer whales occasionally passing through these deep waters.
Evenings on the island are just as magical as the days at sea. Expect sunset swims, beach bonfires, shared family style meals, educational talks about whale behavior, and the quiet beauty of a remote Pacific island.
Note: Our 2026 expeditions are fully booked. Please find our 2027 departure dates below
You will catch a 50 minute domestic flight from Tongatapu (TBU, Tonga's main airport) to our secret location.
To make things as seamless as possible, we offer to book these flights for you (flights not included). These flights depart around 10am but schedules do change. We recommend arriving the day before and spending one night in Tongatapu.
Upon arrival at our secret spot (revealed after booking), our team will greet you at the airport. From there, we transfer by boat to our remote island base surrounded by turquoise waters and coral reefs. If we’re lucky, we’ll get our first glimpse of breaching whales as we head towards our incredible home for the next week. After settling into your beachfront bungalow (one of just five in the lodge), we gather for a welcome dinner and trip briefing as the sun sets over the Pacific.
These days are dedicated to searching for humpback whales and experiencing respectful in-water encounters. After breakfast, we head out by boat across the surrounding islands, scanning the horizon for whale blows and listening for whale songs through the hydrophone.
When whales are located, guides observe their behavior to determine if these whales are open to a visit. When they are, we gently slip into the water. Only small groups of four swimmers at a time enter the water with a guide, ensuring calm and respectful interactions.
We spend approximately five to six hours on the water each day, with lunch served onboard or on a nearby island and stops at vibrant coral reefs for snorkeling. In the afternoon, we return to the island for relaxation, snorkeling the reef, or simply enjoying the island atmosphere.
One afternoon, we’ll have a change of pace and visit a nearby Tongan village of around one hundred residents. We’ll have the chance to chart with the locals, experience traditional weaving demonstrations, learn about island life, and visit small family farms, some of which supply the food we eat!
Evenings include sunset dinners, bonfires on the beach, and optional talks about humpback whale behavior and conservation. For those interested, we can get involved with a local conservation project aimed at identifying and cataloguing whales passing through the area.
After breakfast, we transfer back to the airport for your domestic flight out - domestic flight times vary but if you book a departure out of Tongatepu for 3-9pm on the same day, you should be good.
While this marks the official end of the expedition, many travelers choose to extend their stay in Tonga or continue exploring the South Pacific.
The Kingdom of Tonga is one of the only places on Earth where it is legally permitted to swim with humpback whales. Each year, these magnificent animals migrate thousands of miles from Antarctica to the warm tropical waters of the South Pacific to give birth and raise their calves.
While several regions in Tonga offer whale tourism and some of these areas are undoubtedly crowded, the Secret Islands where we are based remain one of the most untouched and special. This island chain sits between Tongatapu and Vavaʻu and is home to only a small number of tourism operators. Vast stretches of ocean remain completely quiet and uncrowded. We stay at the ONLY accommodation option on our end of the island, so you won’t see any other guests outside of our group. This is a truly intimate and unique expedition.
In contrast to destinations like Moorea or Vavaʻu, where boat traffic can be high during peak whale season, our location offers something rare: space! Fewer boats mean calmer waters, less pressure on the whales, and more natural and curiosity-led interactions.
Our guides are experienced marine professionals who prioritize whale welfare above everything else. We never chase whales or force encounters. Instead, we wait for whales to show curiosity and interest before we enter the water.
These respectful practices often result in extraordinary interactions where whales approach swimmers on their own terms and engage with playful curiosity.
Traveling with Elsewheria means fully immersing yourself in this remote ocean environment without worrying about logistics. Our island base, experienced guides, and carefully designed itinerary create an intimate expedition where guests arrive as strangers but leave as friends connected by a shared love for the ocean.

We are a licensed, conservation-first operator and aim to swim every trip. But whales are wild - Ethical wildlife encounters happen on the animal’s terms. If whales are resting, traveling, or showing signs of disturbance, we move on. This approach protects the whales and ensures that when encounters do happen, they are calm, natural, and unforgettable. If conditions or whale behavior don’t allow it, we may observe them without entering the water. In such cases, your safety and their well-being take priority.
We work only with licensed local operators and experienced whale guides who follow Tonga’s strict regulations. Approaches are slow and respectful, swimmers enter the water quietly, and whales are always given plenty of space to control the interaction.
Never. Tonga limits encounters to very small groups; typically just four swimmers and a guide at a time. This keeps the experience intimate, quiet, and far less intrusive for the whales.
Tonga’s regulations are among the strictest anywhere. Only permitted operators can run trips, encounters are carefully controlled, and whales are never chased or surrounded. The result is one of the rare places on Earth where humans can share the water with humpback whales while keeping their well-being the top priority.
If you are prone to seasickness, please bring appropriate seasickness medication with you. Being prepared will help ensure a more comfortable experience.
No. Entering the water is optional. You can stay on the boat at any time and still enjoy watching the whales from the surface.
Your safety is our top priority. Our team consists of highly qualified and experienced professionals, including internationally certified skippers with over 40 years of combined experience. Our guides are professionally trained in-water guides, trained lifesavers, PADI-certified instructors, certified swimming instructors, highly trained medics, and Tonga-certified. We also have many years of experience working with wildlife in the water and a strong understanding of whale behaviour, ensuring encounters are conducted responsibly and safely.
