things to do in kauai

If you’re planning a trip to Hawaii and wondering which island to explore, Kauai—affectionately known as the Garden Isle—might just steal your heart. This lush paradise isn’t just photogenic; it’s brimming with unique experiences that blend tropical nature, Hawaiian culture, and unforgettable adventure.

So, what are the best things to do in Kauai? Whether you’re chasing waterfalls, beach-hopping, or just soaking in the aloha spirit, this guide will walk you through the most amazing places and experiences the island has to offer.

Explore the Breathtaking Napali Coast

Ever dreamt of seeing towering green cliffs that look like they’ve been painted by a fantasy artist? That’s the Napali Coast.

You can’t just drive there—this rugged and raw stretch of coastline is accessible only by boat, helicopter, or a serious hike. But oh, it’s worth the effort.

Why it’s special:
Imagine 4,000-foot emerald cliffs, sea caves, waterfalls tumbling into the ocean, and rainbows that feel like they’re just for you.

Ways to explore:

• Helicopter Tour: Fly over the coast and witness scenery that would put any movie to shame (and yes, it’s been in several).
• Boat Cruise: Sunset catamaran tours offer not just views, but dolphin sightings and snorkeling too.
• Kalalau Trail: If you’re up for a challenge, the 11-mile trek is as grueling as it is rewarding.

It’s the kind of place that stays in your soul forever.

Swim Beneath Wailua Falls

You’ve probably seen Wailua Falls even if you’ve never been to Kauai. It’s that iconic double waterfall often featured on postcards—and the opening scene of the old TV show Fantasy Island.

Here’s what makes it magical:
It’s easily accessible and doesn’t require a long hike to view. Plus, early risers might catch rainbows shimmering in the mist!

Insider tip:
Visit after a heavy rain—safely, of course—and the power of the falls is jaw-dropping.

And if you love metaphors: standing next to Wailua Falls feels like being next to nature’s very own orchestra.

Snorkel in Tunnels Beach

If you’re a fan of marine life, you have to snorkel at Tunnels Beach.

What to expect:
Crystal-clear waters, a vibrant coral reef system, and a good chance of spotting sea turtles. The beach is framed by dramatic mountain backdrops, making it equally perfect for Instagram and meditation.

When to go:
In summer, the waters are calmer, and visibility is best. Winter swells can be strong, so always check conditions.

It’s like stepping into an underwater dream you never want to wake up from.

Drive the Waimea Canyon—The “Grand Canyon of the Pacific”

How often do you get to say you’ve seen a canyon in the middle of a tropical island?

Waimea Canyon stretches over 10 miles long and plunges 3,600 feet deep. It’s rugged, red, and utterly unlike any other Hawaiian landscape.

What to do there:

• Take a scenic drive along Waimea Canyon Drive.
• Stop at lookout points like Pu’u Hinahina for panoramic views.
• Hike the Canyon Trail to Waipo’o Falls for a mix of jungle and jaw-dropping vistas.

Pro tip:
Go early in the morning for the best light and fewer crowds.

If the Napali Coast is Kauai’s dramatic front, Waimea Canyon is its wild, untamed heart.

Stroll Through Hanalei Town

Hanalei is the soul of North Shore Kauai—a laid-back town surrounded by taro fields, mountain peaks, and old-style charm.

Here’s why it’s worth a visit:

• Cute local shops and boutiques selling everything from surf gear to handmade jewelry.
• Art galleries and food trucks with ono (delicious) Hawaiian flavors.
• The nearby Hanalei Bay Beach is a dreamy spot to chill or learn to surf.

Strolling through Hanalei feels like walking through a Hawaiian daydream. It’s the kind of place where time slows down… and you’re glad it does.

Visit the Spouting Horn Blowhole

Located on the South Shore near Poipu, the Spouting Horn is a natural lava tube where ocean waves shoot through, creating a water geyser and a whooshing sound you’ll never forget.

Fun legend alert:
According to Hawaiian myth, the Spouting Horn is the voice of a trapped lizard spirit trying to escape the rock. Kids love this tale!

Tip:
Go at high tide for the most dramatic blowhole action.

It’s nature’s version of a water fountain—but way cooler and steeped in lore.

Take a Dip in Queen’s Bath

Queen’s Bath is one of Kauai’s most fascinating natural pools, carved out of lava rock and fed by the ocean.

What makes it unique:
It’s not your average swimming hole—it’s like having your own private saltwater spa, but you must go when the seas are calm. High surf can make it dangerous.

Getting there:
It requires a short but muddy hike near Princeville.

Be cautious:
Check safety reports and never go during high surf warnings.

Think of Queen’s Bath like a crown jewel: rare, beautiful, but not without risk.

Watch the Sunset at Poipu Beach

You know those sunsets where the sky turns molten gold and the waves seem to glow? That’s Poipu Beach.

Why it’s famous:

• Safe, family-friendly swimming.
• Excellent for beginner snorkeling.
• Sea turtles often come ashore at dusk to nap on the sand.

Poipu is one of the few spots on Kauai where you can snorkel in the morning, build a sandcastle in the afternoon, and watch turtles at sunset.

It’s like nature planned the perfect day just for you.

Hike the Sleeping Giant Trail (Nounou Mountain)

Up for a morning adventure? The Sleeping Giant trail offers spectacular views without needing an ultra-marathon level of fitness.

Why hike it?

• 4 miles round-trip.
• Scenic switchbacks through forest and ridges.
• Legend has it the mountain is the form of a giant who ate too much and took a nap.

View from the top?
Epic. Like standing on the edge of the world looking out at paradise.

If you’re not into long hikes, this one hits the sweet spot between effort and reward.

Sample Local Flavors at Food Trucks & Farmers Markets

What’s a trip to Kauai without tasting the island?

Try these local eats:

• Shave ice (yes, it’s different from a snow cone!)
• Fresh poke bowls.
• Kalua pork, loco moco, and plate lunches from food trucks.
• Exotic fruits like rambutan and lychee at weekly markets.

Where to go:

• Hanalei Farmers Market (Saturdays)
• Kapaa Art Walk (first Saturdays)

Eating in Kauai is a journey of its own—one that hits all the sweet, savory, and “where has this been all my life” notes.
