Top Big Island Waterfall Hikes & Viewpoints
1. ʻAkaka Falls State Park
Located along the scenic Hamakua Coast just north of Hilo, ʻAkaka Falls State Park is home to perhaps the most famous waterfall Big Island Hawaii has to offer. The trail is a paved 0.4-mile loop that winds through a dense rainforest overflowing with giant bamboo, wild orchids, and towering tree ferns.
- Distance: 0.4-mile loop trail
- Difficulty: Easy (Paved, includes stairs)
- Access Fee: Non-resident entrance fee applies plus parking
- Bonus View: Along the loop, you will also see Kahuna Falls, a 100-foot cascade veiled by lush jungle foliage.
2. Rainbow Falls (Waiānuenue)
Situated within Hilo city limits, Rainbow Falls is renowned for the brilliant morning rainbows that form in its mist when the sun hits the water droplets at the right angle (typically between 8 – 10 am). The waterfall cascades 80 feet over a natural lava cave that Hawaiian legend identifies as the home of Hina, mother of the demigod Maui.
- Distance: Less than 0.1 miles to primary overlook
- Difficulty: Very Easy
- Access Fee: $5 per person plus $10 per car
- Insider Tip: Walk up the paved stairs to the left of the main overlook to view the massive ancient banyan trees at the top of the trail!
3. Peʻepeʻe Falls & Boiling Pots
Just one mile upstream from Rainbow Falls along the Wailuku River lies Peʻepeʻe Falls and the Boiling Pots section. The “Boiling Pots” are a series of hexagonal basalt pools formed by cooling lava flows. When river levels are high, water rushes through subterranean lava tubes, creating a churning effect that resembles boiling water.
- Distance: Short walk to viewpoint
- Difficulty: Easy overlook view
- Access Fee: Free
- Safety Note: Swimming is strictly prohibited here due to hidden underwater lava tubes and unpredictable, life-threatening undercurrents.
4. Kulaniapia Falls
For travelers seeking a private, tranquil experience with the option to swim, Kulaniapia Falls is on a private 42-acre estate. This 120-foot waterfall drops into a serene pool surrounding manicured grounds.
- Distance: 0.5 miles to pool base
- Difficulty: Moderate
- Access Fee: Day Pass or Overnight Stay required
- Activities: Permitted swimming, paddleboarding, and kayaking when safety conditions permit.

6. Waiʻale Falls
Located off the beaten path just above Rainbow Falls, Waiʻale Falls is a beautiful multi-tiered cascade along the Wailuku River. While less crowded than neighboring state parks, the trail to get closer is unmaintained and requires navigating uneven, mud-slicked ground.
- Distance: ~0.6 miles round-trip
- Difficulty: Moderate
- Access Fee: Free
- Tip: The top bridge viewpoint offers excellent photos without needing to scramble down slippery embankments.
Public vs. Private Waterfall Access: What You Need to Know
When planning your Big Island waterfall hikes, understanding access regulations is vital. Many visitors arrive expecting to swim beneath every waterfall, only to discover that public state parks prohibit swimming for conservation and safety reasons. Additionally, vast stretches of land along Hawaii rivers are private property or sacred Hawaiian cultural sites (Kapu). Always obey posted signs, stay on designated public trails, and reserve advance permits or day passes when visiting private waterfall estates like Kulaniapia.
Important Safety Tips for Hawaii Waterfall Hikes
Exploring waterfalls in a tropical ecosystem requires preparation and respect for natural forces. Keep these safety rules in mind during your excursion:
- Beware of Flash Floods: Weather near mountain peaks can change instantly. Even if it’s sunny in Hilo, torrential rains upriver can transform calm streams into rushing flash floods within minutes. If water turns muddy or rises rapidly, exit the stream bed immediately.
- Never Jump or Dive: Submerged rocks, shifting lava ledges, and debris make cliff jumping extremely dangerous in Hawaii waterfalls.
- Leptospirosis Awareness: Fresh water streams in Hawaii can contain Leptospira bacteria. Avoid swimming with open cuts or scratches, and never drink untreated freshwater from streams or falls.
- Pack Proper Footwear: Tropical mud makes trails slick. Wear sturdy hiking shoes with good traction or high-grip water shoes.
- Book a Guided Hiking Tour: Your safety is your guide’s top priority so you can focus on having fun! They’ll stay updated on the weather and flash floods and know the areas where you can safely jump into and swim in the water.

Which Big Island waterfalls can you swim in?
Public state parks like ʻAkaka Falls and Rainbow Falls do not permit swimming due to hazardous conditions and steep cliffs. However, private tours like Hawaii Zipline & Hiking Tours offer waterfall swimming guided hikes. Always check local guidelines before entering the water.
Are there waterfalls on the Kona side of the Big Island?
The Kona coast (the West side of the Big Island) is dry and sheltered from the trade winds, so there are no major waterfalls on the Kona side. Nearly all prominent waterfalls in Hawaii on the Big Island are found along the wetter Hilo and Hamakua coasts on the East side.
What is the tallest waterfall on the Big Island?
The tallest easily accessible public waterfall on the Big Island is ʻAkaka Falls, which drops 442 feet. Hiʻilawe Falls in Waipiʻo Valley is taller at 1,450 feet, but access into the valley is restricted to residents, making ʻAkaka Falls the top choice for travelers.
