100% Tongan-owned and operated, and with over 30 years of knowledge of Tongan waters and 15 years of operating whale tours, Deep Blue Diving is a worthy go-to for your whale swimming experience! They offer full-day trips of seven to eight hours, usually departing in the morning at 7 am to experience calmer seas and the best whale activity.

Deep Blue also offers two boats: a smaller boat ideal for small groups of swimmers and a larger 15 m (49 ft) boat, unique in Tonga's whale-watching landscape,ideal for groups with a few watchers on board. The latter carries up to 25 passengers (not that you often share a tour with that many) with a crew-to-guest ratio of 2:1.

Their larger boat also caters to the elderly and disabled while often being a more comfortable option for those more prone to seasickness, it also has an onboard toilet! The boat travels at a calm and unhurried pace, taking a slower approach than smaller boats, which is said to feel less harassing to the whales and more comfortable for passengers.

If you're after an affordable whale-watching experience without swimming, Deep Blue's spacious boat typically has room to accommodate watchers.

Other features of their tours include whale behaviour commentary and sometimes the opportunity to see rescued turtles released back into the wild. Lunch is provided on board, with options varying from curry to chicken nuggets and other meals.

Return times depend on whale sightings but typically arrive back around 2:30 pm.

Deep Blue also operates scuba diving and snorkelling tours outside of the whale season, which you can learn more about in The Best Snorkel & Scuba Dive Tours in Tongatapu.

For a full-day adventure with whales, join a whale swimming experience with Tanoa Expeditions. Whale watching tours with Tanoa Expeditions last the full seven hours per Tonga's whale watching laws.

What sets this operator apart is their larger-than-average crew of three people, a captain, guide and deckhand, providing extra support and safety for up to eight to nine guests maximum. This means more personalised attention and a smoother experience on the water.

The day starts at 7:30 am at their office, where you'll get fitted for wetsuits and fins before departing from the wharf at 8:30 am. Your seven hours on the water can be very flexible; swimming with humpback whales in the morning if the whales are keen, then enjoying lunch on a deserted island with fantastic snorkelling amongst the coral.

Everything you need is included, lunch, snacks, water, towels, wetsuits, fins and even sunscreen. Better yet, the boat is comfortable enough to enjoy all day, offering an inside sheltered section if things get a bit breezy, while there's also a marine toilet on board.

Tanoa Expeditions have a very respectful approach to the whales whilst also ensuring guests have a safe and fun time.

Although they accept cash and credit card, operating out of the Tanoa International Dateline Hotel, note that there is a 4% credit card fee, that's normal in Tonga, as explained in What is The Best Way to Pay in Tonga?

A Tongan-owned and operated tour, Tuna Moana offer full-day whale swim experiences. Their modern boat is well-designed for optimum topside whale watching right around the vessel, as well as atop the crow's nest!

The boat is also pretty low to the water, making it even easier to get in and out of the water for swimmers. There are often two/three guides on the boat at a time with a maximum of eight guests onboard.

All the usual fixings are included, such as lunch. If you have a good whale swim in the morning, you can ask to stop for lunch at one of Tongatapu's stunning islets.
