Seeing the arc of a rainbow emerge from the mist of a powerful waterfall is a quintessential Big Island experience. In Hilo, that experience centers around Rainbow Falls, known locally as Waiānuenue Falls.
Yes, Rainbow Falls is worth visiting. Its accessibility, beauty, and the frequent appearance of rainbows make it a compelling stop for anyone exploring the Hilo side of the island. It's an iconic natural landmark, easy to enjoy without extensive planning or difficult hikes.
Witnessing the Rainbow: Best Time to Visit Rainbow Falls
The waterfall is named for the rainbows often visible in its mist. To best witness this fenômeno, plan your visit in the morning, between 9:00 AM and 10:30 AM. During these hours, the sun is typically at an optimal angle, shining directly onto the falls and scattering light through the voluminous spray, producing vibrant, arcing rainbows. Clear, sunny days naturally offer the best chance. While rainbows are not guaranteed, the falls themselves are magnificent any time of day.
Rainbow Falls is part of the Wailuku River State Park and is open daily from 7:00 AM to 6:00 PM. No entrance fee is required.
Getting There: Location and Parking
Rainbow Falls is conveniently located just outside downtown Hilo, typically a 10-15 minute drive from the Hilo International Airport (ITO) or the cruise ship terminal. Its proximity to town makes it an easy addition to any Hilo itinerary.
Directions from Hilo:
- From downtown Hilo, head west on Kamehameha Avenue (Highway 19).
- Turn left onto Waianuenue Avenue.
- Continue on Waianuenue Avenue for approximately 1.5 miles.
- Rainbow Falls State Park will be on your right.
There is a dedicated, free parking lot right next to the viewing platforms. The walk from the parking lot to the primary viewing area is short, paved, and wheelchair-accessible, making it ideal for visitors of all mobility levels. The upper viewing area, which offers an alternate perspective and a glimpse of the banyan tree grove, involves a short flight of stairs.
Beyond the Plunge: What to See and Do
The Upper Viewing Area and Banyan Grove
While the main viewing platform offers a spectacular frontal view of the falls, a short set of stairs leads to an upper viewing area. From here, you can gaze down at the Wailuku River's gentle flow above the falls and explore a tranquil grove of large banyan trees. The roots of these ancient trees create tunnels and fascinating natural architecture, offering a different sensory experience.
Pe'epe'e Falls & Boiling Pots
Approximately one mile upstream from Rainbow Falls, also within Wailuku River State Park, are Pe'epe'e Falls and the famed "Boiling Pots." These natural pools are fed by the Wailuku River, and during high water flows, the turbulent water appears to boil and churn as it funnels through lava rock formations. There is a separate parking area for Pe'epe'e Falls and Boiling Pots, accessible via Waianuenue Avenue, just a bit further upstream. It's a different, more rugged kind of beauty, showcasing the sheer power of the river.
Note: Swimming in the Boiling Pots and the Wailuku River surrounding these areas is extremely dangerous and strictly prohibited due to strong currents, unpredictable surges, and hidden underwater hazards.

Queen Lili'uokalani Gardens
For a change of pace after visiting the falls, consider the Queen Lili'uokalani Gardens in Hilo. These 24.7-acre authentic Japanese gardens are the largest outside of Japan, offering serene beauty with meticulously manicured landscapes, pagodas, ponds, and bridges. It's a peaceful retreat, perfect for a leisurely stroll.
Downtown Hilo Exploration
Hilo itself offers a charming, historic downtown. Explore local boutiques, art galleries, and diverse dining options. The Hilo Farmers Market, open daily but largest on Wednesdays and Saturdays, is an excellent place to sample local produce and handcrafted goods. The area retains an appealing, old-Hawaii character.
