Tour Rating
This cruise leaves the bay and runs the open coast. Expect swell, wind, and spray. You stay on the boat, but you need to be steady while it moves. Our captain reads conditions every morning and makes the call before we leave the harbor.
Book at your level. Check the rating and the local weather before you book. Be honest about your experience.

About the Tour
Old Hawaiʻi from the water. In an hour and a half, we run past the breakwall and up the Hāmākua Coast to Onomea Bay: sea cliffs, hidden coves, and waterfalls dropping straight into the Pacific.
Along the way your crew tells the story of this coast. Ancient Hawaiian village sites, the plantation sugar mills that built Hilo, and the cliffs that kept so much of it hidden from the road.
On a clear day, Mauna Kea and Mauna Loa rise behind it all. It is the best view of the east side you can get.

FAQs
Will we see waterfalls?
Yes. The Onomea coast has falls year-round. They are biggest after rain, which in Hilo is often.
Will we see dolphins?
Sometimes. They are wild, so we cannot promise it. If they show up, we give them room.
Will I get seasick?
This is open ocean, so it is possible. If you are prone to it, take medication before the trip. It does not help once you are already sick.
Will I get wet?
Maybe a little spray. Bring a layer and a case for your phone.
What if the weather is bad?
Our captain makes the call before we leave the harbor. If it is not safe, we do not go, and we will work with you to reschedule.
