1. Wailua Falls – The Iconic Twin Waterfall

Wailua Falls on Kauai, Hawaii — a dramatic twin waterfall cascading 80 feet into a lush, tropical pool, seen from the roadside lookout near Lihue.

Location: North of Lihue 
Height: ~80 feet 
Access: Easily accessible by car


If you’ve ever dreamed of seeing a postcard-perfect Hawaiian waterfall, Wailua Falls delivers. Featured in the opening credits of the classic TV show Fantasy Island, this dramatic double-tiered cascade plunges nearly 80 feet into a serene pool below. Its beauty and accessibility make it one of the most photographed and visited waterfalls on Kauai. 


Why You Should Go: 

  • No hiking required—enjoy breathtaking views from the roadside lookout. 
  • Early morning light creates a misty rainbow, perfect for photographers. 
  • Ideal for travelers short on time or with limited mobility. 


Travel Tip: Arrive early to avoid crowds and get parking close to the viewpoint. 


2. ʻOpaekaʻa Falls – A Family-Friendly Favorite

ʻOpaekaʻa Falls in Wailua River State Park, Kauai — a 151-foot waterfall flowing down lush green cliffs, viewed from a roadside lookout with a safe viewing platform.

Location: Wailua River State Park 
Height: ~151 feet 
Access: Roadside lookout


Just a few minutes from Wailua Falls lies another gem—ʻOpaekaʻa Falls. Its name translates to “rolling shrimp,” a nod to the freshwater crustaceans that once filled the stream. Cascading 151 feet over lush cliffs into a hidden pool below, this waterfall offers stunning views with minimal effort. 


Why You Should Go: 

  • Easily accessible with a safe viewing platform and interpretive signage. 
  • Close to the Wailua River, offering options for kayaking or boat tours. 
  • A great stop for families or those planning a scenic drive through the east side. 


Nearby Attractions: After visiting the falls, consider stopping at the nearby Poliahu Heiau, a sacred Hawaiian temple, for a cultural immersion. 


3. Hanakāpīʻai Falls – A Reward for the Adventurous

Hanakāpīʻai Falls on Kauai’s Nā Pali Coast — a towering 300-foot waterfall plunging into a jungle pool, surrounded by lush rainforest and steep cliffs, reached via the Kalalau Trail.

Location: Nā Pali Coast, via Kalalau Trail 
Height: ~300 feet 
Access: 4-mile roundtrip hike (moderate to challenging)


For those willing to venture off the beaten path, Hanakāpīʻai Falls is a hidden treasure. Accessible via a side trail off the famous Kalalau Trail on Kauai’s rugged north shore, this 300-foot waterfall crashes into a jungle pool, surrounded by towering cliffs and thick rainforest. 


Why You Should Go: 

  • Unmatched jungle scenery and the adventure of hiking the Nā Pali Coast. 
  • An epic 300-foot drop into a stunning natural amphitheater. 
  • Swim beneath the falls for a truly immersive experience (conditions permitting). 


Hiking Notes: 

  • Trail conditions can be muddy and slippery—wear proper footwear. 
  • The full hike (8 miles roundtrip from Keʻe Beach) takes 4–6 hours. 
  • Check weather and trail conditions before going; flash flooding is a risk. 


Permits: No permit is needed to hike to Hanakāpīʻai Beach and Falls for day use, but parking at Haʻena State Park requires a reservation in advance. 


4. Manawaiopuna Falls (Jurassic Falls) – The Famous Helicopter Falls

Manawaiopuna Falls, also known as Jurassic Falls, cascading 400 feet down a lush cliffside in Hanapēpē Valley on Kauai, viewed from a scenic helicopter tour.

Location: Hanapēpē Valley 
Height: ~400 feet 
Access: Private land; only accessible by helicopter tour


Fans of Jurassic Park may recognize this towering beauty from the film’s iconic opening scenes. Manawaiopuna Falls, also known as Jurassic Falls, plunges 400 feet down a vertical cliff in the heart of Hanapēpē Valley. Because it’s located on private land, access is only possible via a licensed helicopter tour. 


Why You Should Go: 

  • See one of the tallest and most cinematic waterfalls in Hawaii. 
  • Incredible aerial views of Kauai’s remote valleys and rainforests. 
  • Some tours offer a landing at the base of the falls for a closer look. 


Booking Tip: Choose a tour that includes a landing at Jurassic Falls for the full experience. Companies like Island Helicopters are approved to land at the site.


5. Waiʻaleʻale Falls – The Waterfalls of the Wettest Place on Earth

Waiʻaleʻale Falls on Kauai — dozens of thin waterfalls streaming down the lush, mist-covered cliffs of Mount Waiʻaleʻale, viewed from an aerial perspective in Hawaii’s rain-soaked interior.

Location: Mount Waiʻaleʻale, central Kauai 
Height: Varies; multiple falls flow down sheer cliffs 
Access: Aerial view only or guided off-road/hiking tours (very limited) 


Mount Waiʻaleʻale is often called one of the wettest spots on Earth, receiving more than 400 inches of rain annually. The rainfall gives rise to a near-continuous curtain of waterfalls flowing down its emerald walls—an awe-inspiring sight best viewed by helicopter. 


Why You Should Go: 

  • Witness dozens of waterfalls pouring from sheer cliffs into the lush interior. 
  • A mystical, almost otherworldly landscape rarely seen by most visitors. 
  • The ultimate “hidden Hawaii” experience. 


Access Options: 

  • Helicopter tours are the best way to see Waiʻaleʻale’s falls up close. 
  • A few guided off-road/hiking tours approach the base, but these are challenging and require permits. 


Planning Your Waterfall Adventures: Essential Tips

Best Time to Visit Waterfalls in Kauai 

Kauai’s waterfalls flow year-round, but they’re most impressive during or shortly after the rainy season (November to March). That said, flash floods and trail closures are more common in wet months, so always check weather conditions before heading out. 


Safety First 

  • Never swim near or under waterfalls unless clearly designated as safe. 
  • Watch for slippery rocks and fast-moving currents. 
  • Do not trespass onto private land—always respect posted signs and boundaries. 


Gear Checklist 

  • Waterproof hiking shoes or sandals with good grip 
  • Rain jacket or poncho (especially during the wet season) 
  • Dry bag for your phone and valuables 
  • Camera or phone with wide-angle lens for the best shots 
  • Reusable water bottle to stay hydrated on the trail 


Honorable Mentions: More Waterfalls Worth Exploring

While the top 5 are the crown jewels of Kauai, there are many more worth discovering: 

  • Hoʻopiʻi Falls – A local favorite with two-tiered falls near Kapaʻa. Short hike required. 
  • Makaleha Falls – A remote, multi-tiered waterfall at the end of a challenging hike through dense jungle. 
  • Kalihiwai Falls – Often visible from the road near Princeville; some tours offer horseback rides to the falls.

  • Can you swim in any of the waterfalls in Kauai?

    Swimming is allowed at some waterfalls like Hanakāpīʻai Falls, but it’s highly dependent on weather and water conditions. Many falls have strong currents or hidden hazards. Always observe posted warnings and check with local guides before entering the water.

  • Do I need a permit to hike to Kauai waterfalls?
