Chasing Waterfalls on the Hāmākua Coast: The Big Island's Green Side

Say 'Big Island' and most people picture black lava and stark volcanic desert. The windward Hāmākua Coast, north of Hilo, tells the opposite story: a green, dripping stretch of rainforest and deep gulches where waterfalls seem to appear around every bend of the old coastal highway.

The Showpiece Falls

ʻAkaka Falls is the headliner, a 442-foot ribbon reached by a short paved loop through a jungle of ginger and bamboo. Nearby Rainbow Falls, on the edge of Hilo, is easier still — an almost drive-up cascade that throws its namesake rainbows across the morning mist.

The Scenic Detours

The four-mile Old Māmalahoa Highway scenic route peels off the main road into a tunnel of trees, past one-lane bridges and the botanical gardens of Onomea Bay. It is slow, narrow and completely worth it for travelers who would rather wander than tick off a list.

The dry side gets the volcano headlines; the Hāmākua Coast quietly keeps all the waterfalls.

If You Go

• ʻAkaka Falls: a paved 0.4-mile loop, suitable for most visitors
• Rainbow Falls is best in the morning for its namesake effect
• Take the 4-mile scenic route north of Hilo for gardens and gulches
• Expect rain — this is the wettest, greenest side of the island

Come for the postcard view; stay for the slow, salt-air rhythm that keeps travelers coming back.
