Big Island 9-Line Zipline Experience Plus Private Waterfall Swim

The waterfalls are only the beginning. The Umauma 9-Line Zipline and private waterfall swim pairs a lively aerial course with time beside the Umauma River, making it more than a quick zipline outing. I especially like the beautiful Pacific and waterfall views and the chance to swim, kayak, or paddleboard afterward. The main catch is the $347.13 price, plus a long drive if you are staying on the Kona side.

The four-hour experience begins at 10 a.m. at The Umauma Experience near Hakalau. Guides such as John, Rusty, Skippy, Kip, Hunter, Hogg, Avery, and Koda have earned praise for keeping the mood light while taking safety seriously. I also like that the swim stop is private, but you should know the water area is smaller and more pond-like than some people expect, and the water can be cold.

What makes this Umauma adventure worth considering

• Nine zip lines over tropical ravines: You get a full course rather than one short ride, with some tandem lines and chances to try different positions.
• A private waterfall pond after the ziplines: The second half lets you swim, jump from short cliffs, kayak, paddleboard, or rest in the sun.
• Ocean and waterfall scenery: The views often matter as much as the speed, with the Pacific visible from parts of the property.
• A meal is included: The picnic lunch is simple, but useful after a morning of active fun.
• Small-group feel: The maximum group size is 20, with professional guides handling the safety gear and instruction.
• A good family age range: Children must be at least 4 to zip, with an adult present, and the course has suited groups ranging from young children to people in their 60s.

Nine lines through Umauma’s tropical valleys

The zipline portion is the main event, and it is designed as a sequence of nine rides rather than a single dramatic launch. That matters because you have time to settle into the harness, learn the basic movements, and gain confidence before the faster or more playful sections.

The setting does much of the work. You are not simply flying over an open field. The course crosses green ravines, tropical plant life, and areas where waterfalls cut through the property. On clear days, you may catch views toward the Pacific Ocean as you move above the trees.

Some of the lines are tandem rides, which are especially fun for couples, parents with older children, or friends who want to race. The guides may also show you how to turn, go upside down, or try other controlled tricks. You do not need previous zipline experience. The instruction is aimed at first-timers, and the guides check on the group often.

That playful tone is one of the strongest parts of the experience. Guides have been praised for using jokes, music, and encouragement without losing their focus on proper harness use and safe technique. If you feel nervous, you are not left to figure things out alone.

The course is also more flexible than the word extreme might suggest. You can enjoy the ride in a standard seated position, while more adventurous participants may try a spin or upside-down run when the guide says it is suitable. The result is a good mix for a family or mixed-age group.

Why the guides matter here

A zipline course is only as good as the people running it. At Umauma, the guides are a major part of the appeal. Names that come up in the experience include John, Rusty, Skippy, Kip, Hunter, Hogg, Avery, and Koda, though the exact team can change.

You can expect a briefing on the equipment and instructions on how to brake, position your body, and arrive at each platform. The guides handle much of the technical work, including connecting and checking your gear. Their humor helps keep the waiting time between lines from feeling stiff or overly formal.

The best balance is that they make the course feel exciting without treating safety as a joke. That is important if you are bringing children, trying a zipline for the first time, or traveling with someone who is unsure about heights.

You will still need to follow the rules. Closed-toe shoes are required. The weight range is 35 to 275 pounds, and the activity is not recommended for people who are pregnant or have back or neck problems. There is also a small amount of walking, so this is not a completely stationary activity.

The private waterfall swim is more than a short add-on

After the morning zipline session, the experience continues with the private Waterfall Swim and Kayak Tour, scheduled for about noon. This is not a hurried photo stop. The program allows time to swim, kayak, use a stand-up paddleboard, or simply lie in the sun near the Umauma River.

The water area sits below a waterfall, giving the second half a calm, scenic feel after the noise and movement of the zipline course. You can swim near the falls, paddle around the pool, and in some cases jump from short cliffs. For many people, this relaxed portion becomes the favorite part of the day because it offers freedom to choose your own pace.

Still, set your expectations correctly. The so-called pond is not a large lake or an open stretch of river. It is a relatively small pool below a waterfall, and kayaking there is gentle rather than a serious water excursion. One person found the area more swamp-like than expected, while others loved the private setting and the chance to swim without surf, tide, or shark concerns.

The water can be cold. That is refreshing after the zipline course, especially on a sunny day, but it may be a shock when you first get in. Bring a towel if you can. One participant wished they had brought one down to the waterfall.

Lunch is practical, not a culinary feature

A picnic lunch is included between the two parts of the activity. It is best viewed as useful fuel rather than a reason to book the tour. Some people found the box lunch perfectly welcome after the morning’s exertion, while another described the catered sandwich as dry.

That mixed experience is fair warning. If you have particular dietary needs or strong preferences, check what is available before you go. You may also prefer to bring your own food if the operator permits it, but the supplied information confirms only that lunch is provided.

The meal does add value because you do not need to leave the property to find food during the four-hour program. After several zip lines and time in the water, even a basic sandwich can hit the spot.

The scenery is the real star

Speed is fun, but the scenery gives this activity its sense of place. The Umauma River runs through a lush area with multiple waterfalls, tropical vegetation, and steep wooded ravines. The course lets you see the property from above, while the swim portion puts you close to the water.

You may see parts of the Pacific Ocean from the zipline course, a detail that helps distinguish this outing from a standard forest zipline. The changing viewpoint is one reason the nine-line format works well. You are not looking at the same scene for the whole morning.

The waterfalls are also not just background decoration. They shape the course, provide the setting for the swimming area, and create the strongest photo opportunities. If your idea of a Big Island activity includes greenery, flowing water, and a little controlled adrenaline, this combination fits well.

Do not book it only for the waterfall swim, though. The pool is private and attractive, but it is not a vast natural swimming hole. Book it for the whole package: nine lines, scenery, lunch, and an active water break.

Timing, transport, and the Kona-side calculation

The meeting point is 31-313 Old Mamalahoa Highway in Hakalau, and the tour returns there at the end. The listed start time is 10 a.m., with the zipline portion followed by the noon swim and kayak session.

If you are staying near Hilo, the location is relatively convenient. From Kona, the drive takes more planning and can turn a four-hour activity into most of your day. The road trip itself can be beautiful, but you should not schedule a tight activity immediately afterward.

One scheduling detail deserves attention. A booking confirmation may show a 10 a.m. start, while arrival instructions can require you to be there earlier, around 9:15 a.m. Read the latest confirmation carefully and call the operator if the arrival time is unclear. A group once arrived later because of conflicting information and had to be rebooked.

The activity is often reserved well in advance, with bookings averaging about 44 days ahead. That does not guarantee every date will sell out, but it is a sign to reserve early if your schedule is fixed.

Is $347.13 a fair price?

At $347.13 per person, this is not a casual bargain activity. The price makes more sense when you count the full package: professional guides, nine zip lines, access to a private waterfall area, kayaks, stand-up paddleboards, and lunch.

A shorter zipline tour alone might cost less, but it would not give you the same amount of time at the private pool. On the other hand, if you are mainly interested in swimming under a waterfall, the add-on may not feel worth the extra cost, especially if you expected a large natural pool.

I see the strongest value for families and groups who want one organized half-day with several types of activity. You can zip, swim, paddle, eat, and rest without arranging separate bookings. It also works well for mixed interests because one person can be active while another spends time in the sun.

The value is weaker for budget-minded visitors, people who dislike group activities, or anyone who wants a strenuous kayaking trip. This is guided recreation in a managed private setting, not a backcountry expedition.

Who should book, and who should skip it?

You should consider this experience if you want:

• A first zipline experience with clear instruction
• A family activity that works for children aged 4 and up
• A mix of thrills and downtime
• Waterfall scenery without planning your own route
• A private swimming area with kayaks and paddleboards
• A social outing led by upbeat guides

You may want to skip it if you are uncomfortable with heights, cannot wear closed-toe shoes, or fall outside the 35 to 275 pound weight range. It is also not recommended during pregnancy or for people with back or neck problems.

The swim section may disappoint you if you picture a huge lake or a long river paddle. It is a compact waterfall pool, best for swimming, short paddles, jumping from low cliffs, and relaxing.

Bad weather can also change the plan. The activity is subject to safe conditions, and poor weather can lead to a new date or a full refund. That is frustrating if you have driven from Kona, but the operator has correctly put safety first.

Booking and cancellation details to keep handy

You receive confirmation when you book, and the ticket is mobile. The activity is offered in English and is capped at 20 people.

Children must be accompanied by an adult. People who do not zip but accompany at least two paying participants may access the park garden and waterfalls for free, which can be useful for a nonparticipating family member.

You can cancel for a full refund up to 24 hours before the local start time. Cancellations or changes made inside that 24-hour window are not refunded, and late arrivals or no-shows do not receive refunds. Weather cancellations are handled differently, with the option of another date or a full refund.

Should you book the Umauma Zip and Dip?

I would book it if you want a polished Big Island adventure that combines aerial thrills with a quiet hour or two by the water. The guides, scenery, and choice of activities are the strongest reasons to go, and the private waterfall setting gives the day a satisfying finish.

I would not pay this price for the swim alone, and I would not expect a large lake or demanding kayak trip. Check the arrival time, bring mosquito repellent and a towel, wear closed-toe shoes, and leave plenty of time for the drive from Kona. If those details fit your plans, Umauma offers a well-balanced family outing with enough zipline action to keep thrill seekers happy and enough water time to let everyone catch their breath.
