The boat slips away from Kailua-Kona Pier with a low, steady rumble and a breeze that tastes faintly of ironshore and coffee. You stand at the rail as the town shrinks—palms blur into reef-edge—until the Kona Coast opens and the water takes on a deep, whale-sized blue. The naturalist moves through the crowd with a hydrophone in hand; a taped chorus of clicks and low moans hums through the PA and then, live, a drawn-out vocalization that feels like the ocean itself trying to speak.

Adventure Tips
Arrive Early for Boarding
Plan to arrive at least 30 minutes before departure to park at Ilima Court and walk the short block to the pier; late arrivals forfeit their seat.
Pack Motion-Sickness Remedies
Even on calm days a swell can roll—bring preventative meds or acupressure bands if you’re sensitive to sea motion.
Sun and Wind Protection
UV-equivalent sun and a wind layer are essential—sun can be intense on the open deck and evening winds pick up quickly.
Bring a Telephoto or Good Zoom
A 200–300mm equivalent helps capture breaches and tail slaps from the boat; phones work for close blows but limited for action shots.
