A 5-inch fish scales a 442-foot cliff on Hawaii’s Big Island and nobody talks about it

It’s Twice the Height of Niagara

On the northeastern Hamakua Coast of Hawaii’s Big Island, Kolekole Stream drops off a cliff and falls 442 feet into a gorge thick with ferns and moss. That’s roughly twice the height of Niagara Falls.

The water never touches the rock on the way down. It free-falls the entire distance, straight into the mist below.

A short paved trail gets you to the overlook, but the waterfall isn’t the only thing worth watching here. Something much smaller is doing something much harder on the cliff face right next to it.

A Chief Leapt From the Edge and Became the Falls

The park takes its name from Chief ʻAkaka-o-ka-nīʻau-oiʻo-i-ka-wao, a warrior who ruled the nearby village of Honomu.

Hawaiian legend says the chief, overcome with guilt over personal failings, jumped from the cliff and became the waterfall itself.

Some versions say his faithful dog turned to stone at the edge and his grieving wife became a rock at the top of the falls.

A stone in the park called Pōhaku a Pele is said to bring rain when struck with a branch of lehua ʻāpane.

Walk Through Bamboo Groves to the Overlook

The trail starts just off the parking lot and loops 0.4 miles through thick tropical rainforest. You’ll pass towering bamboo, wild orchids, draping ferns, giant philodendron, and bright red lobster claw heliconia.

Small footbridges cross streams cutting through the gorge below you.

There are stairs along the route, so it’s not wheelchair accessible, but most visitors handle it fine. Give yourself 30 minutes to an hour at a slow pace, and you won’t feel rushed.

Two Waterfalls Share the Same Trail

Most people come for ʻAkaka Falls, but the loop trail also passes Kahuna Falls, a smaller cascade that drops from a side stream into the gorge.

Dense vegetation hides much of it, so you’ll get the best view after heavy rain, when the water pushes through the trees with more force. Several smaller chutes and cascades show up along the trail too.

If you’re short on time, turn left at the first junction and head straight to the main falls.

You’ll Hear the Roar Before You See the Water

The sound of the falls reaches you through the trees before the overlook comes into sight.

A covered shelter at the main viewing area keeps you dry when the rain rolls in, and mist rising from the base of the falls can throw rainbows across the gorge on sunny mornings.

The rock walls around you are layers of volcanic ash and basalt, formed by eruptions of Mauna Kea more than 250,000 years ago.

Kolekole Stream keeps the falls running year-round, fed by heavy rainfall on Mauna Kea’s windward slopes.

A Tiny Goby Fish Scales the Entire Cliff

The ʻoʻopu ʻalamoʻo is a native Hawaiian goby fish that tops out at about five inches long. It spawns in Kolekole Stream above the falls, and after hatching, the larvae drift downstream and out to the ocean.

They spend up to six months maturing in saltwater.

Then they swim back up the stream and climb the 442-foot cliff face using suction disks on their bellies.

Interpretive panels at the overlook explain the whole life cycle, and you might spot the fish in smaller streams along the trail.

Red Ti Plants Line the Path Like Torches

Sacred in Hawaiian culture, red-tipped ti plants were believed to ward off evil spirits, and they border the trail on both sides. Blue, red, and pink ginger plants add bursts of color as you walk.

Massive banyan trees tower overhead, their roots cascading down the gorge walls like ropes. Much of what grows here was introduced over the decades, not native to the park.

But the heavy rainfall on this side of the Big Island keeps everything green and thick all year long.

Listen for the ʻIʻiwi’s Call in the Canopy

As the roar of the waterfall fades behind you on the trail, birdsong takes over.

The surrounding forest supports several native Hawaiian species, including the ʻiʻiwi, ʻamakihi, ʻapapane, and ʻelepaio. The ʻiʻiwi stands out with bright red feathers and a curved salmon-colored bill.

You’ll need to look up and stay quiet to spot them in the canopy. Hawaii’s native forest birds grow rarer every year, so a sighting here carries real weight.

Mauna Kea Feeds Every Drop That Falls

Kolekole Stream begins high on the slopes of Mauna Kea, which rises over 13,000 feet above sea level. Measured from its base on the ocean floor, Mauna Kea is the tallest mountain on Earth.

The northeastern side of the Big Island where the park sits ranks among the wettest places on the planet. Nearby Hilo averages more than 100 inches of rain a year.

All that water feeds the stream, keeps the gorge carved deep, and powers the falls without pause.

The Hamakua Coast Keeps Going After the Falls

ʻAkaka Falls sits along the Hamakua Coast, a stretch of northeastern Big Island between Hilo and Waipiʻo Valley.

The Hawaii Tropical Bioreserve and Garden, a 40-acre collection of more than 2,000 plant species, lies nearby along the Pepeʻekeo Scenic Drive.

Waipiʻo Valley, once the political and religious center of ancient Hawaiian culture, served as the boyhood home of King Kamehameha I. The drive along Highway 19 from Hilo to Waipiʻo Valley takes one to two hours with stops.

Grab Fresh Fruit on the Road to the Falls

The village of Honomu sits along the road to the park and has a handful of shops and local food stands. Roadside fruit stands line ʻAkaka Falls Road, selling tropical fruit grown in the surrounding area.

Farther up the coast, the former sugar plantation town of Honokaʻa has local shops, galleries, and food.

The Hamakua Coast once drove Hawaii’s sugar industry, and these small towns still carry that plantation-era character.

Laupahoehoe Point, a coastal park along the drive, holds a memorial to lives lost in the 1946 tsunami.

Legend, Wildlife, and Rainforest in a Single Short Walk

You can see the whole park in under an hour. That’s what makes it hit so hard.

A short paved trail through thick rainforest leads you to a 442-foot waterfall where a Hawaiian chief became legend, where volcanic rock tells a story 250,000 years old, and where a five-inch fish climbs a cliff face that would stop most people cold.

The resort side of the island feels like another world from here. This is the Big Island at its rawest, and it stays with you.

Visit ʻAkaka Falls State Park on the Big Island

You’ll find ʻAkaka Falls State Park at the end of ʻAkaka Falls Road (Highway 220), about 3.6 miles southwest of Honomu and 11 miles north of Hilo.

The park opens daily at 8:30 a.m. and closes at 5 p.m., with walk-ins welcome from sunrise to sunset. Entrance runs $5 per person for non-residents, free for kids 3 and under, and free for Hawaii residents with valid ID.

Bring a credit card because that’s the only payment accepted, and cell reception is limited at the park.
