Big Island 9-Line Zipline Experience Plus Private Waterfall Swim

Hold on tight, then cool off. The Umauma 9-Line Zipline and Waterfall Swim makes a smart pairing: you get fast rides over tropical ravines, then time to swim, paddle, and relax beside a waterfall. I especially like the friendly guides and the lush views toward the Pacific, plus the private pond gives you a quiet change of pace after the zipline. The main drawback is the price, $347.13 per person, and the dip area may feel smaller and less polished than some people expect.

This is a four-hour outing near Hilo, not a casual ride you can squeeze into a busy morning. You need to arrive ready for a 10:00 a.m. start, wear closed-toe shoes, and allow extra driving time if you are staying on the Kona side. The zipline gets the biggest thrills, but I would not dismiss the swim portion too quickly. For many families, the waterfall pool becomes the favorite part.

Five things to know before you book

• Nine lines over Umauma’s tropical valleys: The course mixes speed, height, waterfall views, tandem rides, and playful options such as going upside down.

• A private waterfall pond follows the zipline: You can swim, kayak, paddleboard, jump from short cliffs, or simply sit in the sun.

• The guides are a major strength: Names praised in the feedback include John, Rusty, Skippy, Kip, Hunter, Hogg, Avery, and Koda. The staff earns repeated credit for safety, humor, and helping first-timers relax.

• Lunch is included but simple: Expect a picnic-style meal. Some people found it satisfying after the morning activity, while one person found the sandwich dry.

• Plan for a full morning and early arrival: The activity starts at 10:00 a.m., but arrival instructions may require you to reach the property earlier. Late arrivals and no-shows are not refunded.

Umauma’s setting gives the zipline its character

The Umauma Experience sits at 31-313 Old Mamalahoa Highway in Hakalau, on the northeastern side of the Big Island. This area is known for heavy tropical growth, river valleys, waterfalls, and broad views toward the Pacific. The scenery does much of the work here.

You are not simply moving from platform to platform above a plain field. The lines pass through a property filled with palms, forest plants, ravines, and falling water. One especially useful point from the feedback is that the views can matter as much as the speed. You may find yourself looking out toward the ocean one moment, then crossing above a canyon or waterfall the next.

The property also helps the experience feel like more than a single thrill ride. People who do not zipline can enter the garden and waterfall area free when accompanied by at least two paying zippers. That is useful for a family with one adult who prefers to stay on the ground.

The course accommodates beginners well. You do not need previous zipline experience, and the guides explain the equipment and riding positions. The youngest age allowed to zip is four, although children must be accompanied by an adult. The minimum weight is 35 pounds and the maximum is 275 pounds.

Nine lines, quick movement, and a few tricks

The zipline portion begins at 10:00 a.m. and takes you through nine separate lines. The course includes tandem lines, which let two people ride together, and some sections encourage playful moves. Several people particularly enjoyed going upside down, spinning, or trying simple tricks with guide assistance.

That does not mean you must perform. If you are nervous, you can stick with the basic position and let the staff handle the technical side. The guides are repeatedly praised for checking on everyone, explaining what to do, and keeping the mood light without ignoring safety.

The combination of speed and scenery is the real appeal. Some zipline parks focus mainly on long, fast rides. Here, the views of waterfalls and tropical plant life give the course a stronger sense of place. You get the thrill of flying, but you also see the Umauma River from above.

The course is not ideal for everyone. Ziplining is not recommended for people who are pregnant or who have back or neck problems. It involves a small amount of walking, and you should be comfortable with harness equipment and elevated platforms. Closed-toe shoes are required, so leave the flip-flops in the car.

The strongest praise goes to the staff. Names such as John, Rusty, Skippy, Kip, Hunter, Hogg, Avery, and Koda appear in especially warm feedback. The exact guide team can change, but the pattern is clear: the operation depends heavily on personal instruction and encouragement. That matters if this is your first zipline or if children in your group need extra reassurance.

The private waterfall swim is more than a quick dip

The second part takes place at a private pond beside the Umauma River, near a waterfall. The combined Zip-N-Dip schedule pairs the 10:00 a.m. zipline with a 12:00 p.m. Waterfall Swim and Kayak Tour. You receive time to swim, use a kayak, try a stand-up paddleboard, or stretch out in the sun.

This is where expectations matter. The water area is not a huge lake or a long river trip. One person described the kayaking as a small pool below a waterfall, with no strenuous paddling. Another felt the pond was smaller and more swamp-like than expected. If you want a serious kayaking workout or open-water exploration, this is not that.

If you see the swim as a relaxed reward after the zipline, the setup makes more sense. You can cool off, paddle around the pool, jump from short cliffs, and swim near the waterfall without dealing with surf conditions or ocean concerns. Several families found this part especially enjoyable because everyone could choose a different activity in the same place.

The water may feel cold, especially after the active zipline section. That is part of the appeal for some people and a shock for others. Bring or pack a towel if the operator allows it, since one person wished they had brought one down to the waterfall area. The provided information confirms access to kayaks and stand-up paddleboards, but it does not promise a large beach, extensive facilities, or a long guided river route.

The waterfall itself is the star. You can enjoy the setting without treating the swim as a major athletic event. I would rate this portion as best for families, couples, and mixed-age groups who want choices rather than a strict activity schedule.

Lunch keeps the day moving

A picnic lunch is included between the two portions or during the Waterfall Swim and Kayak Tour. That saves you from leaving the property to find food and makes the four-hour schedule easier to manage.

Expect simple picnic fare, not a restaurant meal. One person called the sandwich dry, while another found the box lunch good after a morning of ziplining. That difference is easy to understand: after several lines and time in the water, a basic lunch may taste better than it would at noon in town.

If you have strong dietary needs, confirm the arrangements before booking. The supplied details only promise a picnic lunch and do not list menu choices. You may also prefer to bring extra snacks and water, though the tour information does not specify what outside food or drink is allowed.

Is $347.13 a fair price?

At $347.13 per person, this is a costly Big Island activity. The value depends on how much of the package you will use.

The price includes professional guides, nine zipline rides, access to a private waterfall swimming area, kayaks, stand-up paddleboards, and lunch. You are also paying for the property itself, the equipment, staff supervision, and the convenience of combining two activities in one visit.

I think the package offers fair value if you want both the zipline and the water time. Booking only a zipline elsewhere may cost less, but it may not give you access to a private waterfall pond or paddle equipment. On the other hand, if you dislike cold water, have no interest in kayaking, or mainly want a short zipline ride, the added cost may not feel worthwhile.

The experience is highly rated, with 94 percent of purchasers recommending it and an overall rating of 4.8 from 170 ratings. That does not erase the occasional complaint about the lunch or the size of the swim area, but it supports the idea that the combination works well for most people.

Timing matters more than the four-hour label

The activity lasts about four hours and ends back at the meeting point. The stated start time is 10:00 a.m., but one scheduling problem is worth noting: arrival instructions may call for you to reach the property earlier than the start time shown on a mobile ticket.

Read every message carefully and arrive early. One family driving from Kona misread the timing and had to deal with rebooking stress, though the Umauma staff helped resolve the issue. That is a practical warning, not a reason to skip the tour.

The drive from the Kona side can take a meaningful part of the day. Build in extra time rather than treating this as a quick side trip. The route toward Hilo and the Hamakua area can be scenic, and one useful suggestion is to consider stopping at Onomea Beach if your schedule allows.

Because the tour starts at 10:00 a.m. and combines two activities, do not schedule a tight afternoon appointment. Weather can also affect the day. If conditions are poor, the operator offers another date or a full refund. One outing was stopped after only two ziplines because of weather and safety concerns. That can be disappointing after a long drive, but the safety decision is sensible.

Free cancellation is available up to 24 hours before the start time. Cancellations made inside that window, along with no-shows and late arrivals, do not receive a refund.

Who will enjoy this most?

This is a strong choice for families with children old enough to meet the weight and age rules, couples seeking an active day, and first-time zipliners who want plenty of staff support. Teenagers also seem well matched to the mix of speed, tricks, swimming, cliff jumps, and paddleboards.

It works especially well for groups with different energy levels. One person can swim, another can paddle, and someone else can sit by the waterfall. The zipline guides also help make the main activity less intimidating for people who have never tried it.

I would think twice if you are looking for a quiet nature walk, a long kayak trip, or a polished resort-style pool. You should also reconsider if you have a back or neck condition, are pregnant, dislike heights, or cannot meet the shoe and weight rules.

The swim area is private, but private does not mean large. You will get a scenic place to cool off, not a broad natural lake. Keep that distinction in mind and you are less likely to feel disappointed.

Should you book the Zip-N-Dip?

I would book it if you want a full activity morning with strong scenery, capable guides, and a mix of thrills and downtime. The nine lines give you a real adventure, while the waterfall pool lets you slow down afterward. The staff’s safety focus is a major reason I would recommend it to first-timers and families.

I would skip the dip only if you know you will not swim or paddle. For everyone else, the second half adds enough variety to justify serious consideration, even though the pond is smaller than some people expect and the lunch is basic.

Before booking, confirm the arrival time, check the age and weight limits, wear closed-toe shoes, and leave room in your schedule for the drive. If you are staying near Kona, plan the day rather than treating Umauma as a quick outing. For an active Big Island day built around waterfalls, tropical scenery, and good-natured guides, this is a convincing package.
