Big Island: 9-Line Waterfall Zipline Experience
Book on Viator →Operated by The Umauma Experience · Bookable on Viator
Nine lines can feel like flying.
On the 9-Line Waterfall Zipline at Umauma, you get guided runs over treetops, rivers, and waterfalls, with Pacific Ocean views from every platform. I especially like that the essentials are handled for you: entrance fees and required gear are included, so you show up ready. The main thing to weigh is that timing depends on group size and weather, and on some days a line can be down for maintenance.
Check-in is straightforward: you drive in, check at the Visitor Center, do a short orientation, get harnessed up at the gear area, then ride in vans to the top for the final safety talk before you fly the course. Guides like Wes and Skippy show up in the feedback as the kind of team that helps you relax and move confidently—right up until you’re taking in those drops and turns.

Key things I’d put on your radar
- Ocean views on every platform, so the scenery doesn’t save itself for the end
- 9 ziplines total, including four dual lines where you can race a friend
- Everything you need is included (entrance fees + required equipment)
- A guided, step-by-step setup: orientation, gear-up, van ride, then launch
- Age and body requirements are clear (4+ to zip, 35–275 lbs, moderate fitness)
- Weather matters, and it can change timing or dates
Price and what the $253-ish covers (value, not just cost)
At $253.41 per person, you’re paying for a full, guided half-adventure with a real equipment setup—harnessing, taking you through the course, and handling the entry side of things. The price also covers entrance fees and all required zipline equipment, which matters on the Big Island where add-ons can quietly stack up.
This tour runs about 2 to 2.5 hours. That timing feels “just right” for most vacation schedules: long enough to get multiple runs, but not so long that you spend your whole day waiting for weather windows or transport.
One more value point: the max group size is 20 travelers, so you’re not stuck in a giant line for hours. Smaller groups usually mean more attention on gear checks and faster transitions between lines.

Where you start at Hakalau and how the day flows
The meeting point is 31-313 Old Mamalahoa Hwy, Hakalau, HI 96710. There’s no hotel pickup, so plan on driving yourself and arriving early enough to handle check-in and the orientation without stress.
Here’s the flow you should expect:
- You drive up and check in at the Visitor Center.
- Staff gathers the group for a brief orientation.
- You walk a short distance to gear-up, meet the guide team, get safety instructions, then get fitted.
- Vans take you to the top of the property for the final safety speech.
- The tour ends back at the Visitor Center where you started.
That “back to the same place” finish is practical. You can head onward with less guesswork about logistics—especially helpful if you’re pairing this with other Big Island plans.
Safety routine: harness checks, uneven ground, and what you actually need
Ziplining is physical, even when it’s exciting. The tour includes a small amount of walking on uneven surfaces, so you’ll want sturdy footing and a calm mindset. It’s also not recommended for pregnant women or people with back or neck problems.
You also need to match the basics:
- Closed-toe shoes required (no sandals).
- Age requirement: must be 4+ to zip. Kids must be with an adult.
- Weight limits: minimum 35 lbs; maximum 275 lbs.
- Fitness level: moderate physical fitness is the target.
I like the fact that the operation builds in multiple “safety talks” moments—orientation at check-in, safety during gear-up, and a final speech at the top. In the experience feedback, people highlight how often staff checked equipment and how reassured first-timers felt.
If you’re nervous, this is where the guide personality really helps. Names like Wes and Skippy show up in the stories as folks who keep the mood light while still staying firm on safety. That balance matters when you’re dealing with heights and motion.
Stop 1: Umauma Experience (the calm before you fly)
The tour’s first stop is the Umauma Experience. Even without a long explanation of exhibits, this stage matters because it’s where you transition from vacation mode into gear-and-guided mode.
This is also where the property feel shows up in the feedback. People mention the grounds as well kept, with spaces like picnic benches and an outdoor hangout area. There’s also mention of food on-site—plus a note about pineapple soft serve—which gives this start a bit more of a “destination” vibe instead of just waiting in a parking lot.
If you’re traveling with someone who won’t zip, there’s a helpful rule: if they are accompanied by two or more paying zippers, they may access the garden and waterfalls for free. That’s a nice option for families and mixed-confidence groups where not everyone wants the harness.
Stop 2: Umauma Falls and the actual zipline thrills
The second stop centers on Umauma Falls, and that’s where the big promise becomes real: you’re going over treetops, waterfalls, and rivers on 9 different ziplines.
What I think makes this special for first-time zippers is the pacing. You don’t just rush from platform to platform. You get structured guidance, and you build confidence as you go. Many people call out how fun it was to feel safe and still excited—like you’re being taught how to enjoy the ride, not just survive it.
The ocean views are the other major draw. The tour description says you’ll get panoramic Pacific Ocean views from every platform, and that’s the kind of detail that changes how the whole course feels. Instead of one scenic moment, you get repeated “look up” opportunities that keep the experience from turning into pure adrenaline.

Racing a friend on four dual lines
A standout feature is that there are four dual lines where you can race a friend. That’s more than a gimmick. When you’re traveling with a partner, sibling, or a kid who wants a challenge, the dual setup turns the ride into an actual game instead of a solo activity.
If you’re going solo, you’ll still get the same course and views, but you’ll lose that direct race moment. If racing matters to your group dynamic, try to coordinate who zips together so the “who’s faster?” energy happens naturally.
What happens if a line is down or conditions change
Weather is required for this experience. If it’s canceled due to poor weather, you’ll be offered a different date or a full refund.
Line maintenance is a separate issue, and it has shown up in the feedback. On some dates, a zipline (including the one people called their favorite) may be down, meaning you might skip a line. On those days, the outcome can vary: some stories mention a discount option, others mention a partial refund, and at least one story says no discount was given. The practical takeaway is simple—keep an eye on any day-of updates from staff, and ask what the adjustment means for your exact run list.
How to dress and prepare so you don’t fight the tour
This is not the place for fancy gear. You’re working with harness equipment and moving over platforms, so focus on comfort and stability.
My quick checklist:
- Wear closed-toe shoes you can trust on uneven ground.
- Skip anything loose that could snag; keep pockets simple.
- Bring a layer if it’s windy or you run cold—ziplines can feel cooler once you’re moving.
- Arrive early. One family noted they weren’t told how early to show up, and they wished they had planned on 30–45 minutes earlier.
Also, think about your comfort with heights. This experience is guided and safety-focused, but you still need to be willing to clip in, lean forward, and trust the system.
Who should book the Umauma 9-Line, and who might skip it
This tour fits best if you want a classic Big Island thrill with actual scenery attached. It’s also a good pick for families with teens through adults, since the minimum age is 4+ as long as a paying adult accompanies the child.
It’s less ideal if:
- You’re pregnant.
- You have back or neck problems.
- You can’t meet the 35–275 lb weight limits.
- You struggle with moderate walking on uneven surfaces.
If you’re visiting with parents in their 70s, couples, or groups with mixed ages, the consistent theme is that staff help people feel safe fast. Guides like Wes and Skippy show up as examples of the kind of team that makes nervous riders comfortable without turning the day into a slow, “hand-holding” experience.
The bottom line: should you book it?
Yes, I’d book this if you want nine guided zipline runs with ocean views from multiple platforms and the chance to race on dual lines. The value is strong because the essentials are included, and the time commitment is reasonable for a vacation day.
I’d think twice if you’re dealing with back/neck issues, pregnancy, or you’re unsure about weather-dependent scheduling. And if your trip window is tight, give yourself buffer time so a weather change doesn’t wreck the day.
If you want a Big Island activity that feels both fun and organized, this is one of the easiest “do it now” choices.
