Swimming with dolphins on the Big Island can be done by people of all ages and swimming skills and is often described as an unforgettable experience that will leave you with memories for a lifetime. There is, however, one big “however”: the well-being of the dolphins.
The ‘swim with dolphins’ tours currently offered on the Big Island can be harmful to the dolphins, and at the moment we don’t recommend any of these tours. If you are lucky you can experience swimming with dolphins when a curious wild dolphin approaches you to check you out. If the dolphin swim is a real ‘bucket list’ activity for for you, you could consider swimming with captive dolphins.
Dolphins in Hawaii
“Nai’a” is the Hawaiian name for dolphins. It refers to any species of dolphins found in the Hawaiian waters, which can mean one of the following four:  The pacific bottlenose dolphin.  The rough-toothed dolphin.  The spotted dolphin.  The spinner dolphin. Of these, spinner dolphins are the smallest and most common dolphins around Hawaii, and the pacific bottlenose dolphins are known for their playfulness and star appearances in aquariums worldwide.
What is the best place on the Big Island to swim with dolphins?
The best places to spot wild dolphins are at the Kona and Kohala (north of Kona) coasts. The weather on this side of the island is good year-round, so don’t forget to pack sunscreen. Being close to dolphins is sure to be one of the highlights of your trip.
How to behave around wild dolphins
Dolphins are very smart and playful mammals and it can seem like great fun for both parties to play with dolphins. However, seeking out and trying to interact with the dolphins disturbs their natural behaviors and can interrupt much-needed rest periods. Spinner dolphins, the dolphins most commonly targeted by swimming with dolphin activities on the Big Island, seek out sheltered bays with sandy bottoms in order to rest. These rest periods are crucial to their well-being. Unfortunately, tours that promise dolphin swims often go to these bays to find the dolphins.
You can read more about efforts to reduce the tourist impact on Hawaii’s spinner dolphins on the very interesting blog Raising Islands about the science and the environment as they relate to the Hawaiian Islands.
- Remain at least 50 yards (1/2 a football field) from spinner dolphins.
- Limit your time observing to 1/2 hour.
- Spinner dolphins should not be encircled or trapped between boats or shore.
- If approached by a spinner dolphin while boating, put the engine in neutral and allow the animal to pass. Boat movement should be from the rear of the animal.
You can find more information at the NOAA “protect dolphins campaign”. Please stay safe and treat the dolphins with aloha – observe them from a distance
SMART on the Big Island
Swimming with dolphins is not thought to be good for the dolphins itself because it interferes with their rest. NOAA recommends staying at least 50 yards away from dolphins when ‘swimming’ with them (read more on the how and why of these guidelines). Out of respect for dolphins and the ocean, please read these guidelines and choose your tour operator accordingly.
Many tour operators on the Big Island (and worldwide) still organize “swim with dolphins” excursions with disregard for the best interest of the dolphins itself. To help improve this, NOAA has started the “Dolphin SMART” program. Dolphin SMART is a unique voluntary recognition and education program encouraging responsible viewing of wild dolphins.
Commercial wild dolphin tours or any commercial vessel that may opportunistically view wild dolphins can participate in the SMART program and get recognized if they successfully demonstrate responsible viewing and advertising of dolphins in the wild and educating patrons on the importance of dolphin conservation.
SMART has only recently expanded to Hawaii, and recognition has not been awarded to any company on the Big Island yet (as of June 2017). If this happens we recommend that you reward the companies that gain SMART recognition by booking your tours through them.
In the meantime there are a couple of things you can do to book the most dolphin-friendly tour:
Swim with dolphins tours
You might bump into dolphins while enjoying one of the many ocean activities on the Big Island, but if you do not want to take that chance, your best bet is to book a dolphin tour. These tours last about 4 hours and set you back around $150. Snacks, water, and snorkeling equipment are generally provided to the guests aboard, but be sure to inquire about this when you book a tour. What you shouldn’t forget to pack is a good sunblock, a bathing suit, and a towel!
Dolphin Quest at the Hilton Waikoloa village ’employs’ captive (resident) dolphins. This way you still get to be in the water close to real dolphins without causing unnecessary harm.
Body Glove Hawaii offers a Dolphin Snorkel adventure for which they guarantee dolphin sightings (or you can go again for free). They adhere to the SMART guidelines and don’t let people in the water with the dolphins. Dolphins often come very close to the catamaran they use for tours as they love to play in the waves behind the boat
Two options for a Dolphin Tour in Kona are Bodyglove cruises and Kamanu Charters. When contacting these (or other) tour operators whose excursions you are considering, please inquire after the procedures they follow and especially if they are SMART certified. This way you let these companies know that you care, which in turn will make them care.
