Umauma Falls Hike: Waterfalls, Gardens & Ziplines on the Hamakua Coast
Not every waterfall in Hawaiʻi makes you work for it, and Umauma Falls is honest about that from the start. This triple-tiered cascade on the Hamakua Coast is reached not by a grueling backcountry trek but by a gentle garden walk on private land, with the option to trade the walking shoes for a zipline harness or an ATV. If you searched for the Umauma Falls hike expecting a wilderness trail, here is the good news: what you get instead is one of the Big Island’s most accessible waterfall experiences, and you can be standing at the lookout within an hour of leaving Hilo.
This is the single complete guide to the Umauma Falls hike and visit. It covers where the falls are, what the walk is actually like, the garden viewing tour, the zipline and other adventure options, entry fees and hours, what to bring, the best time to go, nearby alternatives, and answers to the questions visitors ask most.

Where Umauma Falls Is
Umauma Falls sits on the Hamakua Coast, the lush, cliff-lined stretch of the Big Island northeast of Hilo. From Hilo, drive north on Highway 19 for about 16 miles toward Hakalau, then turn onto Old Mamalahoa Highway to reach the Umauma Experience property at 31-313 Old Mamalahoa Highway. The drive itself is part of the pleasure: the Hamakua Coast is all green gulches, ocean vistas, and small plantation towns, a completely different mood from the Kona side’s lava fields.
An important piece of history explains the access situation. The falls lookout was once reached through the World Botanical Gardens, but in 2008 the lookout point and its surrounding acreage were sold to the Umauma Experience, an adventure company. Today the waterfall sits on private land, and the only way to see it is through the Umauma Experience, whether that means the garden viewing tour or one of the adventure activities. There is no public trailhead and no roadside viewpoint.
The Honest Truth About the “Hike”
Let us set expectations clearly, because the word “hike” oversells it. The Umauma Falls walk is a self-guided garden and river stroll of about one mile out and back, taking most visitors around half an hour. You pick up a map at the visitor center, follow the paved and garden paths down toward the Umauma River, cross several small bridges, wander through the meditation garden and palm forest, and arrive at the falls lookout. It is easy, family-friendly walking, not a workout.
That is not a criticism. The walk is genuinely lovely: guava trees (sample the fruit when ripe), tropical flowers, the sound of the river below, and an observation area at the river walk where you can sit with the falls in view. The visitor center sells sandwiches, snacks, and drinks, and there is a back lanai overlooking the river and the zipline course. For travelers who want a waterfall without a strenuous trek, or for families with small kids and grandparents, this is exactly right.
Do wear proper footwear anyway. The Hamakua Coast is one of the wettest parts of the island, paths and viewing areas get slick after showers, and “easy” still means uneven ground in places. A light rain jacket lives in every experienced Hamakua visitor’s bag.
The Falls Themselves
Umauma Falls is a three-tiered waterfall with a cumulative drop of about 300 feet, spilling down a narrow green valley in three visible steps. The main viewing shelter sits above the principal drop, framing the layered cascade against the valley walls. Like all Hamakua waterfalls, Umauma is rain-fed, which means its personality changes with the weather: after heavy rain it runs full and thunderous (and can turn brown with runoff), while in drier spells it threads more delicately down the rock face. Both versions are beautiful; the full-flow version is the one that makes people gasp.
Ways to Experience Umauma Falls
The Garden and Falls Viewing Tour
This is the base experience and the one most visitors choose. A paid self-guided tour gives you access to the landscaped grounds, the river walk, the meditation garden, and the falls lookout. Final entry is at 4:30 PM. It is the cheapest and calmest way to see the falls, and you can pair it with lunch from the visitor center.
The 9-Line Zipline Tour
The signature adventure is a nine-line, two-mile zipline course that runs over the Umauma River with views of the falls, the ocean, and Mauna Kea. The first four lines are dual lines you ride side by side, the fourth stretches over 2,000 feet above the river, and a 200-foot suspension bridge crosses a water-filled lava tube and fern grotto between lines. At line seven you get a close-up view of the falls’ dual waterfall section. Riders must be at least 4 years old and weigh between 35 and 275 pounds; braking is automatic and hands-free. Expect to pay in the mid-200s per adult, with youth rates slightly lower, plus taxes and fees.
ATV and Waterfall Swim Tours
A 5.5-mile ATV course runs through the property’s ranch land with Pacific views for those who prefer mud to airtime. The private waterfall and river swim tour offers kayaking, stand-up paddleboarding, or simply relaxing at a waterfall on the Umauma River, starting around $75 per person. Horseback riding through the pastures is also offered in partnership with a local stable. In short, the property is built for a full day, not just a photo stop.

Entry Fees, Hours, and Booking
Every way in goes through the Umauma Experience’s booking system. The garden and falls viewing tour has its own admission fee (historically around ten dollars, but confirm current pricing when you book). Adventure tours are priced separately and should be reserved ahead, especially the zipline, which runs at set start times through the day. Final entry for the gardens is 4:30 PM. If you are driving up from Hilo or the Kona side, build in buffer time; Hamakua weather can slow the roads, and you do not want to rush a waterfall.
What to Bring and What to Know
Pack for a wet, tropical coast: grippy walking shoes, a rain jacket, insect repellent, sunscreen, and a camera. Bring cash or a card for the visitor center cafe. Do not expect a wilderness experience; this is a managed property, which means real restrooms, clear paths, and staff nearby. Do stay on the marked paths and respect the private land boundaries. Do not try to reach the falls any other way; there is no public access, and neighboring land is private.
One more consideration: because the falls are rain-fed, the “best” flow and the “best” viewing weather do not always coincide. A rainy morning can mean a spectacular falls display under gray skies, while a sunny afternoon can mean a thinner cascade. Morning visits generally offer the clearest light for photos, and weekdays are quieter than weekends.
Best Time to Go
The falls run year round, but the Hamakua Coast is wettest in winter, which means the most dramatic flows from November through March, paired with the highest chance of rain during your visit. Summer offers drier, sunnier garden walks with a somewhat thinner cascade. Honestly, there is no bad season; just match your expectations to the weather report. After a night of heavy rain, go early for the fullest falls.
Nearby Alternatives
If you want a wilder waterfall hike, Akaka Falls State Park is the classic Hamakua alternative: a paved 0.4-mile loop to a 442-foot plunge waterfall, with a state park entry fee and no private-land logistics. For a full-day adventure from the same area, the town of Hilo offers the farmers market, Rainbow Falls, and the county’s best poke counters. Umauma’s advantage is the combination: waterfall, gardens, and adventures in one stop, with almost no hiking required.
Umauma Falls vs. Akaka Falls: Which Should You Visit?
Travelers on the Hamakua Coast often weigh Umauma against Akaka Falls State Park, and the choice comes down to what kind of day you want. Akaka Falls is the classic: a state park, a paved 0.4-mile loop through rainforest, and a single 442-foot plunge waterfall that is taller and more dramatic than any one tier of Umauma. It is cheaper, quicker, and entirely self-directed. Umauma is the fuller experience: a smaller, triple-tiered cascade, but with gardens, a river walk, a cafe, and the zipline, ATV, and swim tours that Akaka cannot offer. If you want the single most impressive waterfall photo, go to Akaka. If you want a half or full day built around a waterfall, with options for every energy level in the group, Umauma wins. Doing both is easy; they are about 20 minutes apart on the same coast.
Visiting with Kids
Umauma is one of the most family-friendly waterfall stops on the Big Island. The garden walk is short, stroller-manageable on the paved portions, and full of small discoveries that keep kids engaged: bridges over the river, guava to taste, flowers to spot, and the falls themselves as the payoff. The zipline accepts riders as young as 4 (within the 35 to 275 pound range), so older kids and teens can fly while younger ones enjoy the gardens. Bring snacks and water even though the visitor center sells food, because kids and waterfall mist both run on their own schedules.

Why Umauma Falls Is Worth the Drive
Umauma Falls will not test your endurance, and that is precisely its charm. In a state full of waterfalls that demand miles of muddy trail, here is one that asks only for a morning, a pair of walking shoes, and a willingness to slow down among guava trees and river bridges. Add the zipline if you want adrenaline, or just sit at the river walk’s observation area and watch three tiers of white water thread down a green valley. The Hamakua Coast does the rest.
