Hilo Ocean Adventures – Cliffs of Hawaii Onomea Waterfall Cruise

See Hilo from the water on a scenic cruise that follows the Hamakua Coast past rainforest, lava cliffs and quiet coves. The shoreline feels especially dramatic from offshore, with waterfalls dropping toward the sea and traces of old plantation history still visible along the way.

As the boat moves north, your guides share stories about the coast, nearby village sites and the sugar era that helped shape Hilo. Onomea Bay is one of the prettiest stretches of the route, with dense greenery and seasonal waterfalls framed by dark volcanic rock.

When the weather is clear, Mauna Kea and Mauna Loa rise in the distance above the island. Spinner dolphins may also appear near the boat, adding an unexpected bit of wildlife to the day.
