The Top 5 Fun Things to do on Kauai (#1 is a must!)

Inside: The absolute best things to do in Kauai, where to stay, and which tasty treats to try!
Like many people, my husband Dave and I first visited Kauai on vacation years ago. That trip was his first visit to Hawaii’s lovely Garden Isle and my third.
Who knew all those years ago that someday – thanks to a job opportunity for him – we’d live in Hawaii!
Now that we’re fortunate to call the nearby island of Oahu home, Kauai is still one of our favorite places to island-hop for the weekend.
So when the traffic of Honolulu and the stress of busy careers gets to us…
It’s time for a beach, a sunset, and an umbrella drink. Stat.
And there’s no better place to get away from it all than the relaxed island of Kauai.
Why is Kauai the best Hawaiian Island?
Itβs a well-known fact that Hawaii has a variety of beautiful islands to choose from.
Most visitors to Hawaii arrive on the main island of Oahu. And many of those same visitors make the mistake of limiting their Hawaiian holiday to just this single, very popular island.
But while I love Oahu and we now live in Waikiki, it can be a little too busy for some.

What about Maui?
Thereβs no doubt it’s a stunning island, but it can be a bit too touristy. It is, after all, considered the honeymoon capital of the world.

However, more than a year after the Lahaina fires, tourism to the island is still down and they need your support. So please consider planning a visit soon!
Here’s how to do it right: Yes, Go to Maui. But Hereβs What NOT to Do on Your Visit
The Big Island?
Gorgeous! But as the name implies, itβs big. And youβll spend a good part of your holiday just driving from one lovely spot to the next.

What about tiny Molokai?
Yes, itβs the ultimate low-key escape to the Hawaii of old. But with few tourist facilities, itβs better explored on a day trip than as a week-long holiday destination.

So what makes the island of Kauai so special?
Why Kauai Hawaii is the perfect island escape
Miles away from the traffic of Oahu, or the tourist crowds of Maui, the peaceful island of Kauai is my favorite choice for pure relaxation.
In fact, of all the Hawaiian Islands, many experienced travelers consider Kauai to be the best island in Hawaii, and hereβs why.
Nicknamed the Garden Isle, Kauai has it all β pristine beaches, lush rain forests, jagged emerald cliffs, and plenty of gorgeous hiking trails to keep an active traveler busy.
But Kauai is less developed than some of Hawaiiβs other islands.
And that means you can soak up all that natural beauty without sitting in traffic or worrying about tour bus groups. And Kauaiβs compact size makes it easy to explore when you just have a few days.
In fact, the top things to do in Kauai are all just a short drive apart.
And that’s why the island is perfect for our regular weekend getaways or your next vacation!
Now, letβs move on to the fun stuffβ¦where to stay, how to get around, and what to see on Kauai!

Why Poipu (on the South Shore) is the Perfect Home Base
Located at the southern tip of Kauai, Poipu is the most popular beach on the South Shore.
In the winter months, itβs also legendary for spectacular sunset views.
In addition to that perfect crescent of sand and magical sunsets, Poipu truly has it all. Great hotels, restaurants, and shops, all within easy walking distance.
Not to mention the regular wildlife visitors like lounging monk seals and Hawaiian sea turtles (honu).
That’s why I consider it one of the 15 Amazing Beaches to Add to Your Hawaii Bucket List.
Itβs completely possible to use Poipu as your home base, skip the rental car, and book day trips when you feel the urge to explore further afield.
If you decide to go that route, here are all my favorite day trips on Kauai:
Do I need a rental car in Kauai?
Need? No.
But I vote yes.
Hereβs whyβ¦
To really get out and see the island, itβs best to have a rental car. This is true no matter where on the island you stay. Kauaiβs best sights are scattered all over the island.
Luckily, driving on Kauai is easy and distances are short. You can see many of the Garden Isleβs highlights in a single day.
We always use Discount Hawaii Car Rental to book our car and love having the flexibility to drive ourselves around the island. We like to explore on our own schedule, hitting the brakes for every yummy-looking food truck along the way!
Discount Hawaii Car Rental
For rental cars in Hawaii, go to the local experts. They’ll find you the best rate among all the major companies with no booking fees. And their customer support is top-notch.
Plus, if youβre staying in a hotel or condo with a kitchen, youβll need the occasional grocery store run for provisions. More on that nextβ¦
Bottom Line: Yes, you can get by without a rental car. But for ultimate independence, get your own wheels.
Tip: Be sure to book your rental car well in advance, this is a small island with a limited supply.
Best Places to Stay on Kauai
Though we typically only visit the island for weekend stays, most who arrive here plan to stay for at least a week. With that in mind, itβs nice to have a little extra space and maybe even your own kitchen.
Thatβs why we usually book one of the many condo/villa properties on the islandβs south shore.
Vacation rentals abound on all of the main Hawaiian Islands. For our last visit to Kauai, we chose Marriottβs Waiohai Beach Club, right on Poipu Beach.
The sprawling resort boasts three pools, two hot tubs, and lush tropical grounds reminiscent of a botanical garden.
Our 2-bedroom, 2-bath villa was the price of a standard hotel room at some of the islandβs fancier resorts.
The villa was terrific, with a full kitchen, a washer and dryer, and a deep soaking tub with my name on it.
Pro Tip: Donβt miss the resortβs nightly sunset champagne sabering. If youβre not schooled in the art of uncorking a bottle of champagne with nothing more than your average kitchen sword, theyβll teach you. (Itβs quite fun, I once nailed it at the St. Regis Aspen).
Bonus: Once the champagne is open, everyone gets a free taste.
Other great resorts in Poipu
My other favorite resorts in the Poipu area are:
Both offer all the resort amenities for a relaxing vacation in the best area of Kauai (in my opinion!).
But don’t worry! If one of Kauai’s big fancy resorts is out of your budget (or just not your style), Kauai also has some pretty awesome affordable hotels.

Top 5 Best Things to Do on Kauai
One of the great things about Kauai is that you can fill your days with sightseeing and adventure.
Or, you can just relax and do nothing at all.
And while some quality time planted on a beach chair sipping the aforementioned umbrella drinks is a must, don’t forget to make time for a few of Kauaiβs must-see sights.
Here are a few of my favorite Kauai things to do:
#1. Whale Watching & the Na Pali Coast
If thereβs one thing you absolutely cannot miss while visiting Kauai, itβs a visit to the Na Pali Coast. That’s why it’s also #1 on my Kauai Bucket List.
Read More: Bucket List Kauai: 40 Unforgettable Things to See, Do, and Eat! ππΊπ§
Whether by air or sea (or both!), make this your top priority on the island.
Perhaps most famous as the backdrop for the movie Jurassic Park, this rugged and inhospitable 25-mile stretch encompasses about a quarter of Kauaiβs coastline along the north shore.
With the exception of the arduous 11-mile Kalalau Trail hike, this part of Kauaiβs north shore is only accessible to visitors by two means β air or water.
The Na Pali Coast by Air or Sea?
Often referred to as Hawaiiβs state bird, a myriad of helicopter companies stand at the ready to swoop you over the north shore coastline to ooh and aah over verdant emerald valleys and waterfalls cascading down 3,000ft cliffs.
Flight times range from 25-90 minutes and most depart from the Lihue Airport. In addition to helicopter tours, there are also fixed-wing sightseeing planes for island tours.
If you’re interested in seeing the Na Pali Coast by air, these are the two best flight tours on the island:
Kauai ECO Adventure Helicopter Tour
This 50-minute flight with Blue Hawaiian Helicopters is the #1 tour on the island. It’s truly a once-in-a-lifetime island experience.
Kauai Deluxe Sightseeing Flight (fixed wing plane)
View all of Kauai’s amazing beauty from the air on this 65-minute scenic flight with Wings over Kauai. Bonus: Every seat has a window.
Seeing Kauai from the air is the best way to appreciate all of the island’s interior beauty.
But for my money, to see the Na Pali coast, nothing beats getting out on the water on a catamaran.
Like helicopter flights, there are a number of companies offering catamaran trips. Most offer either a morning trip that includes snorkeling and lunch or a sunset trip that includes dinner.
On our recent visit, we chose the morning trip with Kauai Sea Tours aboard the “Lucky Lady” and it was terrific (I also heard glowing reviews about Captain Andyβs β but they were fully booked on the day we wanted to go).
The excursion was not billed as a whale-watching trip.
However, any time you hit the water around the Hawaiian Islands during whale season (November to April) youβre likely to catch sight of βvacationingβ Humpback whales.
Wowed by the Whales
And boy did we!
In fact, this non-whale-watching trip turned out to be the best whale-watching trip Iβve ever taken. (And that includes Alaska, New Zealand, Cabo & even Antarctica β all during prime whale season.)
Humpbacks are considered the most acrobatic of the whale population and during our cruise, dozens of whales showed us why!
Some propelled themselves from the water in a dramatic full breach, while others entertained with playful pectoral slaps and tail slaps.
It was an amazing afternoon weβll never forget.
When not watching whales, we made friends with spinner dolphin pods who swam playfully along with our boat as we cruised along the stunning coastline.
Letβs just say it was a pretty epic day and an experience not to be missed if you visit the island, especially during whale season.
Important Note: Keep in mind that the weather in the Hawaiian islands can be especially unpredictable during whale season. Boat trips and scenic flights are often canceled due to weather conditions so book them early in your stay so you have the chance to try again if your trip is canceled.
#2. Waimea Canyon
Next on the list of spectacular island sights, head to west Kauai and the incredible Waimea Canyon.
Considered the βGrand Canyon of the Pacific,β youβll definitely appreciate the reference when you stop for a peek at this magnificent geological wonder along Highway 550 on the islandβs east side.
Stretching 10 miles long and over a mile wide, the 3,600ft deep canyon offers visitors numerous hiking trails and lookout points to take in its beauty.
Like the Grand Canyon, Waimea Canyonβs walls display changing hues depending on the sunβs direction during the day. Oh, and don’t miss a stop by the Red Dirt Waterfall.
Tip: Sunrise is an especially stunning time to visit Waimea Canyon.
While you’re in the Waimea area, don’t miss one of my favorite food trucks, Mama Bear’s Kitchen. Located right by First Hawaiian Bank, it’s only open on weekdays from 7am-2pm so plan accordingly.
Everything on the menu is great but the “Monte Bear Cristo” is my absolute favorite. I have considered booking a mid-week flight from Oahu when the craving for this sandwich strikes.
#3. Kauaiβs Best Waterfalls
If youβre short on time and want to see one of Kauaiβs most gorgeous waterfalls, hereβs another tip.
Follow Highway 56 a few minutes north of Lihue on Kauaiβs east side and stop at the lookout point for Wailua Falls (two waters).
Shout out to my fellow children of the 80βs, this is the waterfall featured in the opening scenes of the TV show βFantasy Island.β
Amazingly, the best views of this beauty are right off the highway.
If you have more time, thereβs also a boat trip up the Wailua River that leads to the lush Fern Grotto (a lava tube filled with ferns).
Also easily accessible from the highway, Opaekaβa Falls on the east side of the island is best viewed in the mid-morning when the sun is in the best position for photos.
For a more intensive waterfall outing, Secret Falls is located up the Wailua River and is the highlight of most river kayak tours. I did this kayaking trip to Secret Falls with my parents on my first visit to Kauai and it was excellent!
Tip: Bring good water/hiking shoes, itβs about a 20-minute hike to get to the pond at the base of the falls.
#4. KΔ«lauea Point Lighthouse
Located at the northernmost point of Kauaiβs north shore, the Kilauea Lighthouse and National Wildlife Refuge is a fascinating stop on a driving tour of the island.
The vintage lighthouse (circa 1913) boasts panoramic views of the Northshore.
Humpback whales and dolphins can often be spotted from this lofty cliff-top perch, but the main attraction is the bird life.
This bird nesting sanctuary is home to large colonies of native Hawaiian seabirds like the Red-Footed Booby, Laysan Albatross, and the Great Frigate Bird.
Iβve spotted Blue-Footed Boobies while in the Galapagos, but who knew there were Red-Footed Boobies, too?
Learning. This is why we travel, no?
The entry fee for adults is $10 and, like many places in Hawaii in the post-Covid era, advance reservations are now required. There is also a well-stocked gift shop on-site.
Tip: If you can’t score a reservation on the day you want to go, the overlook at the end of KΔ«lauea Road is always open to view the lighthouse, seabirds, and KΔ«lauea Point from a distance.
Note:Β The lighthouse is closed for renovations from February 17 β April 30, 2025. Luckily, during that time youβll still be able to view the lighthouse from the lookout point.

#5. Sample Kauaiβs Top Tasty Treats
Finally, my favorite subjectβ¦FOOD!
Kauai has a plethora of delightful options. Here are a few picks you shouldnβt miss:
Two words: Food Trucks!
Hawaii is well-known for these culinary upstarts.
Delectable food trucks serving everything from smoothies to fish tacos are a great way to enjoy some of Kauaiβs freshest local cuisine on a budget (or even if youβre not!).
We’ve already covered my love for Mama Bear’s Kitchen, here are a few more…
Al Pastor Taco Truck
My favorite food truck on the windward (eastern) side of Kauai is the Al Pastor Taco Truck in Kapaa. Youβll easily spot this one on the right as you drive north toward Hanalei along the less-visited Coconut Coast.
Tip: Itβs worth lingering along the east side of the island to explore more of the Coconut Coast area. Think affordable hotels, beachside restaurants, and an authentic local aloha vibe.
This husband and wife team serve up fresh fish tacos and Mexican fare daily from one of the most popular trucks on the island.
We always stop for tacos on the drive up the coast to Hanalei. I love the shrimp tacos and the fish tacos are Dave’s favorite. Both are exceptional!
For more local knowledge on the islandβs best food trucks and where to find them, Kauaiβs Best Food Trucks is your go-to guide!
Island Flavors at the Juice Stand
A local juice stand is another great place to enjoy the flavors of Kauai.
Try Little Fish Coffee, just across the street from the Marriott Waiohai resort. This colorful little coffee and smoothie hut is always packed (for good reason!) and we love to start our day there in the morning.
Donβt miss the Angry Dragon smoothie or a delicious acai bowl for breakfast.
Go Local at the Farmerβs Market
Another fun option?
Support the local farming community by visiting one of the many farmerβs markets. Happening daily around the island, the markets are advertised in all the local tourist publications.
The Wednesday afternoon farmerβs market at Poipuβs Kauai Culinary Market offers a variety of the areaβs fresh fruits and vegetables. Plus locally-made products and tasty food stands to sample. Open from 3:30pm β 6:00pm every Wednesday, this one is a must.
Uniquely Hawaiian β Shave Ice
One uniquely Hawaiian treat is shave ice.
Note: Donβt make the tourist mistake of calling it βshaved ice.β Itβs shave ice, drop the D.
This ice-based dessert resembles a snow cone but is made with shaved (Iβll allow it) ice instead of crushed ice which produces a fine βsnow-likeβ ice that allows it to fully absorb flavored syrups.
The flavor varieties are seemingly endless. Donβt miss the local treats like mango, lychee, guava, and passionfruit.
Here are a few of my favorite places on Kauai to try this tempting Hawaiian dessert:
- The Fresh Shave (Koloa)
- Wishing Well (Hanalei)
- Waikomo Shave Ice (Poipu)
You’ll also want to be sure to try Hawaii’s best sweet treat, malasadas! Kauai Bakery in Lihue is the best spot on the island to try them, but here are a few more:

The 5 Best Beaches in Kauai
Whales, canyons, waterfalls, and, yes, the islandβs beaches are pretty terrific, too. (If you can find the time!)
Kauai has 113 miles of coastline and nearly half of that is taken up by golden, perfect beaches.
Here are some of the best beaches in Kauai:
1. Poipu State Beach Park
One of my favorites, and typically our βhome beachβ when we visit. Itβs a perfect arc of silky sand with a shallow, protected bay for snorkeling and swimming.
Thereβs no doubt this is one of Kauaiβs most beautiful beaches. But a lifeguard on duty also makes Poipu Beach one of the best beaches for families.
And the perfect sunset views in the winter months make it a great choice for couples.
And the best part about Poipu Beach? It’s a favorite spot for basking Hawaiian sea turtles (honu) and Hawaiian monk seals. You’ll have to keep a safe distance so you don’t disturb them, of course!
Tip: Just down the road from Poipu Beach, don’t miss a stop at Kauai’s famous blowhole, Spouting Horn!
2. Lydgate Park
Located on the east side of the island, this is a great stretch of beach for strolling or sunning. It has two protected tidal pools that provide an excellent swimming area for kids. There are lifeguards, a huge playground, restrooms, and picnic tables.
This one is a top spot for beach bums looking to unwind.
3. Hanalei Beach Park
Hugging lovely Hanalei Bay on the north shore, Hanalei Beach Park is a gorgeous beach to visit.
Unfortunately, Hanalei Bay is typically only suitable for swimming in the summer months due to the high north shore surf in the winter.
4. Tunnels Beach
Just west of Hanalei Bay along the north shore, Tunnels Beach is home to some of the Garden Isleβs best snorkeling (during the summer months when the ocean is calm). Also called Makua Beach, this 2-mile stretch of golden sand is located at Haena Point.
Fringed with swaying coconut palms, the βtunnelsβ here are actually lava tubes that form underwater caverns in the reef. Note: Parking here is extremely limited so arrive early to get a spot.
5. Polihale State Park
The longest sand beach in Hawaii at 15 miles in length. Located on the west side of Kauai, just past the Pacific Missile Range Facility, access is via a 10-mile bumpy dirt road off the main highway.
As far as Kauai beaches go, if youβre looking for a wide, remote beach with mesmerizing sunsets, this is the place for you. If youβre looking for a swimmable beach with facilities, skip this one. Riptides and currents here can be extremely dangerous.

A Perfect Stay on Kauai
Our visits to the Garden Isle are always too brief.
This lush, mountainous island is one of those rare places in the world that always leaves you wanting more.
From incredible Kauai beaches and jagged cliffs to scenic waterfalls and energetic whales, the peaceful island of Kauai is a nature loverβs dream vacation.
If youβre not careful, this slow-paced island paradise will steal your heart.
And not just for the umbrella drinks.
