Kailua-Kona Whale Watch: Hydrophone Cruise for Up-Close Humpback Encounters
Select participants and date
You step off the sidewalk into trade wind air and the warm salt breath of the Pacific. The Kailua Pier is a short walk from the shopping strip, but aboard the catamaran the island feels farther away—only sea and a sky rimmed with Mauna Loa and Hualālai. Within minutes the Kona coast slips astern and the ocean widens; crests lift and fall like a crowd holding its breath.

Adventure Tips
Arrive Early and Park Nearby
Park at the Body Glove Cruises office (75-5629 Kuakini Hwy) and allow 5–7 minutes to walk to the pier; boarding begins 30 minutes prior to departure.
Dress in Layers
Deck conditions change quickly—bring a lightweight windbreaker and a sun layer to handle both cool mornings and bright reflections.
Prevent Seasickness
If you’re prone to motion sickness, take medication an hour before boarding and choose a midship seat on the lower deck for less motion.
Protect Your Gear
Bring a fast lens or zoom and use a strap; salt spray and sudden movements make secure handling important for cameras and binoculars.
Local Insights
Wildlife
- Humpback whales (Megaptera novaeangliae)
- Spinner dolphins often bow-ride near Kona waters
History
Humpbacks migrate to Hawaiian waters each winter to breed and calve; cultural traditions recognize the kohola as an important marine presence and modern protections helped populations recover.
Conservation
Operators follow NOAA whale-watching guidelines and the Marine Mammal Protection Act; maintain distance, avoid disrupting behavior, and use hydrophones to listen rather than approach animals.
