Kauai is also known as Hawaii’s Garden Isle because of the emerald cliffs, majestic waterfalls, and pristine beaches. Unlike its busier neighbors, I find Kauai has a slower, more serene vibe, yet with a good balance of both adventure and relaxation. There’s plenty of activities here, so if you cannot decide what to do in Kauai on your first trip, we narrow down the signature and unique activities for a memorable experience.
Top Experiences To Do In Kauai
Take a Helicopter Tour
Kauai’s interior is so rugged that most of it is only accessible by air. I know, helicopter tours aren’t cheap. But if you can swing it, this is one of those once-in-a-lifetime experiences that’s totally worth it. You’ll fly over canyons, waterfalls, and the insane peaks of Mount Waialeale, one of the wettest places on Earth.
There’s a very popular eco adventure helicopter tour available that has huge windows to enjoy the scenic ride. But if you are up for an adventure and challenge, there are also helicopters with doors off for full unobstructed view! There are no middle seats, which means all seats/passengers are right by the door on either side.
Pro tip: Book morning flights for the clearest views!
Explore the Na Pali Coast
The Na Pali Coast is Kauai’s showstopper, with towering sea cliffs and lush valleys plunging into the Pacific. You’ve got three ways to see it, and each option offers stunning views of hidden valleys, waterfalls, and sea caves.
By Sea: A catamaran cruise or Zodiac raft tour gets you up close to sea caves, hidden beaches, and vibrant coral reefs. These trips often include snorkeling stops where you can swim alongside tropical fish, sea turtles, and even dolphins. Summer months (May-September) offer the calmest waters. For those who don’t really want to get in the water, a sunset cruise is a very popular option.
By Air: By now, you probably realise air tours are very popular in Kauai. This is because they give you a breathtaking aerial view of the jagged coastline and cascading waterfalls. If you don’t have a fear of heights, this would be the option to go for.
The best thing about exploring by air is that planes are the fastest mode among the three here, so these sightseeing flights will cover not just Na Pali Coast but also popular spots like Waimea Canyon State Park.
By Land: Lastly, if you’re up for a hike, the first two miles of the Kalalau Trail lead to Hanakapiai Beach with dramatic ocean views along the way. Don’t forget your waterproof camera for snorkeling and a good pair of hiking shoes if you’re hitting the trail.
Whatever you choose, remember to book your tour in advance, especially during peak season (May-September).
Adventurous Activities In Kauai
Hike Waimea Canyon
Nicknamed the “Grand Canyon of the Pacific,” Waimea Canyon is a beautiful landscape of deep reds, greens, and golds stretching 14 miles long. The colors are stunning, especially in the morning light.
For some of the best viewpoints in Kauai, make sure to stop at Waimea Canyon Lookout and Pu’u Hinahina Lookout. Both spots offer sweeping vistas of the canyon’s dramatic red cliffs, lush green valleys, and the distant ocean.
The Canyon Trail to Waipo’o Falls (approx 3-mile roundtrip) is a good option if you’re up for a hike. This trek is of moderate difficulty, but rewards you with stunning views of the canyon and leads to a picturesque waterfall.
If you don’t want or unable to hike, there’s still plenty of tours that take you to experience different highlights in the Waimea Canyon (some even lump in a Wailua River Boat Cruise). So you can get all the views without the sweat 🙂
Kayak the Wailua River
That said, if you’re up for a little adventure, you can actually kayak down the Wailua River. This isn’t just any river; it’s sacred to Hawaiians and winds through lush jungle scenery.
There’s a kayak and hike tour that saves you from all the logistics, planning and reading. You get to enjoy the water adventure while learning the cultural importance of the river, then hike to a gorgeous 120-foot waterfall hidden in the forest.
Kauai Packing Tip: If you are planning to participate in outdoor adventures on both land and water; waer shoes will come in really handy when you want to combine some of these activities together. Make sure to have a pair with good grip because some of the trails can be muddy.
Scuba Dive for Experienced Divers
For certified divers, Kauai is known for the incredible underwater adventures. You can join a tank boat dive with other experienced divers to explore vibrant reefs, lava formations, and marine life like turtles, rays, and even reef sharks.
For those who like to explore the underwater world, this one is a no-brainer. Morning dives typically have the best visibility, but you can always check with them for recommendations of the season.
Don’t fret if you’re not a certified diver because there’s plenty of snorkeling opportunities in different sites around Kauai, like the Na Pali Coast ones. South Poipu is another popular spot. That said, you should definitely be confident in water for any of these activities. Otherwise, opt for sightseeing on the boats!
Go Ziplining Through the Jungle
Ok, I know there’s some of you who prefer the mountain over the sea. No worries, there’s thrilling activities too apart from just trekking.
Ziplining in Kauai is relatively popular because of the lush nature. Imagine soaring over lush rainforests, deep valleys, and even waterfalls. It’s an adrenaline rush with a view.
This fun Kauai Zipline Adventure takes you across an 8-track course, which goes through some of the island’s most stunning landscapes, with experienced guides ensuring you’re safe and having the time of your life.
Remember to wear secure shoes (no flip-flops!) and leave loose items behind, as you’ll want both hands free to enjoy the ride.
Chill And Cultural Things To Do In Kauai
Experience a Traditional Luau
No trip to Kauai, or Hawaii for the matter, is complete without immersing yourself in a traditional Hawaiian luau. And since it’s a core part of the culture, it’s very easy to take part in one. This is essentially a fun evening of authentic Hawaiian food, music, and dance.
Watch as the kalua pig is pulled from the imu (an underground oven), the smell alone is incredible. You’ll also dig into dishes like poi (it’s an acquired taste, but give it a try) and lomi salmon, all while hula dancers sway to the beat and fire knife performers light up the night.
Book your tickets early, especially during peak season, and show up a little early. You might even get to try your hand at lei-making or some hula moves! Hawaiians are very passionate people and keen to share their culture.
Take a Sunset Catamaran Cruise
As I mentioned above, but there’s few better ways to end your day in Kauai than sailing along the Na Pali Coast at sunset. Grab a mai tai, enjoy the ocean breeze, and just stare at the burst of colors in the sky (ok, you won’t be staring because you can bet everyone will be busy taking photos).
Be sure to book early as these cruises fill up fast, especially during peak season. You probably also want to dress comfortably but well, for the gram.
If you want to take it up a notch, some cruises like this highly-rated one, also include a delicious dinner and drinks, just covering all your necessities for the evening.
Enjoy Kauai’s Sweet Side
The Wailua area is known for its lush greenery and scenic views. BUT it’s also famous for its incredible chocolate! Kauai actually has some amazing chocolate makers who craft delicious chocolates from local cacao. If you have already gone for your Luau experience, this is a chance to try the sweet side of the island’s flavors.
There’s a chocolate tasting tour that takes you to see the cocoa trees and sample chocolates from different parts of the world. It also includes a deeper look into the nature around the island, with a visit to the Princeville botanical gardens
It’s a more chill way to explore Kauai’s culture and nature while enjoying some delicious treats.goo
Join a Movie Locations Tour
It’s pretty obvious that Kauai is very much about nature and outdoor sports, so those often take center stage when it comes to the most popular things to do. However, movie buffs will likely enjoy this, especially if you want to go for something more relax.
Did you know Kauai has starred in some of Hollywood’s biggest blockbusters? Films like Jurassic Park to Pirates of the Caribbean have used the island’s stunning landscapes as its backdrop, along with countless films. Bring your camera and your imagination for this, you’ll want to recreate your favorite movie moments.
A guided movies location tour is the best option for this one. You’ll get to visit filming locations and hear behind-the-scene stories. Visit the shooting locations of Jurassic Park, Pirates of the Caribbean, Gilligan’s Island, Blue Hawaii, Six Days, Seven Nights, Tropic Thunder, and more.
But There’s More…
There are plenty of other things to do in Kauai. My list is what you shouldn’t miss, but there is the Limahuli Garden & Preserve, Waimea Town, and tons of other beaches where you can snorkel and surf. The island can offer so much more especially if you have time or planning on going back again (which I’m sure you are).
