Big Island Waterfall Wonders Slingshot Private Tour offers a unique way to explore some of Hawaii’s most iconic natural attractions. For $424.24 per group (up to 2 people), you get to spend approximately 8 hours zipping around the island in a Polaris Slingshot, a fun and open-air vehicle that promises an exhilarating drive and plenty of scenic stops. The itinerary includes visits to Rainbow Falls, Akaka Falls, Umauma Falls, and Waipio Valley Lookout, with extra stops at Mauna Kea and charming towns like Honokaa and Waimea. This tour combines the thrill of a convertible-like ride with the chance to see some of the island’s most iconic waterfalls and viewpoints.
What we really appreciate about this experience is how flexible and personalized it can be—since you’re driving, you set the pace and the stops. Plus, the stops themselves are carefully chosen to highlight Hawaii’s lush landscapes, from waterfalls to botanical gardens and cultural sites. The second highlight? The drive itself. Navigating the winding roads along the coast and up into the mountains in a Polaris Slingshot makes the journey as memorable as the destinations.
However, a word of caution: this isn’t a perfect tour for everyone. Some reviews point out issues with GPS navigation and vehicle restrictions that can cause delays or add unforeseen costs. If you’re a traveler who relies heavily on precise directions or doesn’t want to handle the drive yourself, this might be less ideal. Plus, there’s a significant security deposit required, which could be a consideration for some.
This tour suits adventurous travelers who enjoy driving, scenic beauty, and a touch of freedom in their sightseeing. It’s particularly good for those who want a private, customizable experience rather than a large group bus tour. Those comfortable with driving a manual vehicle and who appreciate having control over how long they spend at each stop will find this an engaging way to see the Big Island’s waterfalls and viewpoints.

In-Depth Review of the Big Island Waterfall Wonders Slingshot Tour

Planning more time in Big Island of Hawaii? We've covered other experiences worth considering.
Starting Off: A Scenic Spin in a Polaris Slingshot
From the moment we start, it’s clear that this tour is about the joy of the drive as much as the sights. The Polaris Slingshot itself is a sleek, sporty vehicle that feels more like riding in a convertible with a twist of adrenaline. It features an open cockpit, so you’ll want to dress appropriately for Hawaii’s weather—sunny, with a chance of wind-in-your-hair thrills.
The tour begins at Waikoloa Village, where you pick up your vehicle. Since it’s a private tour, only your group will be behind the wheel, giving you the freedom to customize your pace—whether you want to linger at a waterfall or just cruise along the coast. We loved the way the self-guided navigation helped us feel in control, though some reviews mention GPS issues, so be prepared for occasional hiccups.
The Roller Coaster of Old Saddle Road
Our first stretch takes us along the Old Saddle Road, famously called the “rollercoaster of Big Island” for its twists, turns, and elevation changes as we climb to 6,600 feet. This drive is a highlight in itself, offering sweeping vistas of mountains and lush greenery. The moderate thrill of the winding road sets the tone for the day ahead.
A major stop early on is the Mauna Kea Visitor Information Station at 9,200 feet. Here, visitors can learn about the astronomers’ work, enjoy educational programs, and, if the weather cooperates, gaze at the stars. This stop is free and offers a chance to understand the scientific importance of Mauna Kea—an essential part of Hawaiian cultural and natural landscape.
Waterfalls and Botanical Gardens
Next, the tour hits the famous Rainbow Falls in Hilo, which is an absolute must-see. At just 80 feet tall, Rainbow Falls may be modest in size, but its reputation for creating rainbows in the mist makes it magical. The lush rainforest surrounding the falls is home to wild ginger and monstera plants, which add to the tropical magic. As one reviewer put it, “It’s beautiful to see cascading water with rainbows in the mist,” and we agree—a classic Hawaiian postcard.
The Hawaii Tropical Botanical Garden offers a peaceful walk among over 2,000 plant species. The variety of palms, heliconias, and bromeliads — many over 100 years old — makes this a botanical feast. It’s a good reminder of the island’s rich flora and a break from the visual intensity of waterfalls.
Akaka Falls State Park is next, with its towering 442-foot waterfall. The trail here is a lush rainforest stroll, where you can see wild orchids, bamboo groves, and ferns. The folklore surrounding the falls adds a cultural layer to the natural beauty, making it more meaningful.
Umauma Falls and Waipio Valley
The Umauma Falls are a highlight for many—three waterfalls on the Umauma River, with the largest cascading into a tranquil pool. The setting is perfect for photos and nature walks. If you enjoy lush scenery, this spot doesn’t disappoint.
The Waipio Valley Lookout offers perhaps the most breathtaking view, with steep terraced walls, waterfalls, and a black sand beach. It’s a popular spot for photos, but some visitors choose to hike or take guided tours down into the valley, respecting its cultural significance. The views are expansive and give a true sense of the island’s dramatic landscape.

Charming Towns: Honokaa and Waimea
The tour makes stops in Honokaa for local shopping and a chance to sample Malasadas at Tex Drive-In—a sweet treat that’s well-loved by visitors. Then, in Waimea, you get a taste of the ranching culture, with sights of Parker Ranch and the town’s agricultural vibe. Waimea also hosts the Keck Observatory and the Canada-France-Hawaii Telescope, pointing to Hawaii’s role as a hub for astronomy.
Practical Considerations and Tips
We appreciate that the tour lasts about 8 hours, giving you ample time to see multiple sights without feeling rushed. The vehicle rental includes helmets, and the self-guided navigation allows you to explore at your own pace. However, be prepared for the security deposit—$750 or $1,500—and note that a valid driver’s license and being 21 or older are requirements.
While the flexibility is a major plus, some reviews mention GPS problems that caused delays, and one visitor found that a stop required a 4WD vehicle, which the Slingshot isn’t. Planning ahead and bringing extra snacks or gear might be wise since food and gas expenses are on you.
Who Will Love This Tour?

If you’re someone who enjoys the freedom of driving, has a sense of adventure, and loves scenic drives combined with natural beauty, this tour is a good fit. It’s especially suited for couples or small groups comfortable with manual transmission and with a spirit of exploration. If you’re seeking a highly structured, guided experience, this might not be ideal.
This experience offers a blend of natural wonders, cultural insights, and the thrill of a sporty ride—perfect for those who want a personalized day out in the Hawaiian landscape. Keep in mind that the local stops are free, but you’ll need to budget for food, gas, and the security deposit.
The Sum Up

This Big Island Waterfall Wonders Slingshot tour is like a choose-your-own-adventure in a scenic playground. It’s ideal for travelers who crave the freedom to set their own pace, enjoy beautiful waterfalls and viewpoints, and embrace the fun of driving a sporty vehicle. The stops are thoughtfully selected to showcase the island’s lush landscapes, and the flexibility means you can linger or move quickly—whichever suits your mood.
On the downside, GPS issues and vehicle restrictions can complicate the experience somewhat. It’s best for confident drivers who’re comfortable navigating winding roads and handling a manual vehicle. If you’re after a guided, hassle-free tour, you might prefer a bus or small-group trip, but for those looking for a more personalized, adventurous day, this could be just right.
This tour offers a lively, scenic, and flexible way to see some of Hawaii’s most spectacular waterfalls and landscapes—an authentic taste of the Big Island’s natural beauty combined with the thrill of a private drive.
