8 Best Kauai Waterfalls Everyone Should Visit
Kauai’s waterfalls spill down emerald cliffs in a way that almost feels unreal—like you’ve wandered onto a movie set.
These 8 best waterfalls in Kauai range from easy roadside stops to epic hikes through rainforest, with plenty of swimming holes along the way.

1. Wailua Falls
Wailua Falls is Kauai’s poster child for waterfalls, dropping 80 feet in a dramatic double stream.
Just north of Lihue, it’s one of those rare gems you can drive right up to—no hiking boots required.
The water splits in two before tumbling into a picture-perfect pool. You get a front-row view from the roadside lookout.
Best For: Anyone looking for a quick stop with knockout views and easy photo ops.
2. Hanakapiai Falls
Hanakapiai Falls plunges 300 feet into a lush, hidden pool deep along the Na Pali Coast State Wilderness Park.
But be warned: you’ll have to earn this one with an 8-mile round trip hike on the Kalalau Trail.
The journey kicks off at Hanakapiai Beach and winds two miles inland through wild, muddy valleys. Ocean views, jungle, and then the falls themselves, roaring in the middle of nowhere.
Best For: Adventurers who want a challenge and some of the best scenery on the island.

3. Secret Falls (Uluwehi Falls)
Secret Falls doesn’t give up its secrets easily—you’ll need to kayak two miles up the Wailua River, then hike another mile through thick jungle just to reach this gorgeous 120-foot cascade.
Once you get there, though, it’s all worth it. Swim right under the falls, let the mist cool you off, and just soak it all in.
Most people go with a guided tour—they’ll handle the gear and show you the way.
Best For: Those who want a bit of everything: paddling, hiking, and a swim under a hidden waterfall.
4. Opaekaa Falls
This 151-foot beauty sits right off Kuamoo Road, so you can just pull over and take it all in.
The name means “rolling shrimp”—apparently, freshwater shrimp used to tumble down with the water (nature is wild).
Best time for photos? Late morning, when the sun hits the falls just right. No hiking, no fuss, just a killer view over the Wailua River Valley.
Best For: Anyone after a no-hike, high-reward waterfall with classic Kauai views.

5. Hoopii Falls
This short, muddy hike near Kapaa winds through rainforest to not one, but two waterfalls. The 1.8-mile trail is manageable for most, though you’ll probably get your shoes dirty.
The first falls is a favorite for cliff jumpers. Both have pools for swimming, if you’re up for a dip after your trek.
Best For: Families or groups who want a bit of adventure, a swim, and a taste of the jungle.
6. Waipo’o Falls
Waipo’o Falls drops 800 feet in two epic tiers into the heart of Waimea Canyon—Kauai’s answer to the Grand Canyon, just with more rainbows.
You can spot the falls from several lookouts along Highway 550. If you’re feeling ambitious, the Canyon Trail (about 3.6 miles round-trip) gets you close enough for a swim.
Best For: Hikers who want scenic views, a waterfall swim, and bragging rights.

7. Jurassic Falls
If you’ve seen Jurassic Park (who hasn’t?), you’ll recognize this 400-foot waterfall—Manawaiopuna Falls—from the movie’s opening shots. It’s deep in Hanapepe Valley and getting there is half the adventure.
You can only visit by helicopter, since the falls are on private land. It’s exclusive, cinematic, and kind of surreal to see from above.
Best For: Movie buffs who want to relive a Hollywood moment from the sky.
8. Makaleha Falls
Ready to get muddy? This wild jungle trek near Kapaa is a badge of honor for anyone up for a real adventure.
The 2.6-mile trail winds along a stream, weaving through thick greenery and forcing you across rivers more than once.
Twin cascades plummet nearly 200 feet into a pool that just begs for a swim. Expect to scramble over boulders and slip on roots—it’s all part of the fun, and the payoff at the end is absolutely worth it.
You’ll want solid hiking skills and a good sense of direction—there aren’t really signs out here (only markings on some trees), and the trail can get sketchy.
Best For: Anyone chasing a rugged waterfall adventure and a killer swimming hole far from the crowds.
