Best Things to do in Kauai - Trip Tradition

Kauai stands apart from its Hawaiian siblings. The “Garden Isle” nickname barely hints at what visitors encounter. Your hiking boots can be just as essential as flip-flops. Frequent rainfall (particularly on the north shore) creates those impossibly dramatic green mountains that can dominate almost every photo of yours. Roughly 90% of the island is inaccessible by road. This geographical reality forces most of the 1.5 million annual visitors to explore just a fraction of what exists, while vast wilderness areas remain untouched.

Kauai has everything you need to do, from heart-pounding indoor activities to outdoor activities. From relaxing to exploring lush rainforests and waterfalls and visiting famous film locations like Jurassic Park, Pirates of the Caribbean and Indiana Jones, you’ll have all the fun things to do in Kauai you’ve chosen to visit. In this comprehensive guide, we’ve covered everything you need to do in Kauai, encouraging you to have a great trip and lots of fun. So, let’s start with some top things to do in Kauai. From budget-friendly adventures to splurge-worthy experiences, consider this the ultimate cheat sheet for experiencing authentic Kauai – the version locals hope visitors will discover and respect.

Top 21 Things to do in Kauai, Hawaii

1. Na Pali Coast: Visit Kauai's Amazing Showstopper

The Na Pali Coast is why most people come to Kauai. Those massive green cliffs plunging straight into the ocean are Hawaii’s version of the Grand Canyon, except wetter and greener. Hollywood loves this place too, those cliffs you saw in Jurassic Park, that’s Na Pali.

There are three ways to see this natural wonder, including the following:

  • Hiking
  • Boat tours
  • Helicopter tours

2. Waimea Canyon: The "Grand Canyon of the Pacific"

Whoever nicknamed Waimea Canyon the “Grand Canyon of the Pacific” wasn’t exaggerating. This 14-mile-long gash in the earth reveals layers of red, brown, and green that’ll have you burning through your phone’s memory with photos. What they don’t tell you in the brochures is that the canyon was formed not just by the Waimea River carving through rock, but by a massive volcanic collapse. The whole western chunk of the original volcano fell into the ocean. 

Here are some of the best ways to see it:

  • Drive to the lookouts if you’re short on time.
  • Hike the Canyon Trail to Waipoo Falls if you’ve got energy and 3-4 hours.
  • Combine with a trip to Kokee State Park (they’re next door to each other)

3. Beaches That'll Ruin All Other Beaches For You

Kauai’s beaches should come with a warning label: “May cause permanent dissatisfaction with beaches elsewhere.” Each coast has its personality:

  • Poipu (South): Family-friendly with calm waters and regular monk seal visits. Great for kids and skittish swimmers.
  • Hanalei Bay (North): That postcard-perfect crescent beach with mountains behind it.
  • Tunnels/Makua (North): Snorkeling paradise with a backdrop that’ll make your Instagram followers hate you.
  • Polihale (West): The wild west – 17 miles of mostly empty beach where the road ends and Na Pali begins. Sunset here is practically a religious experience.

Beach access is free, making this one of the best free things to do in Kauai. However, north shore beaches can be dangerous in winter (roughly November-April).

4. Gardens That Give the "Garden Isle" Its Name

All of Hawaii is lush, but Kauai takes it to another level. Mount Waialeale gets slammed with about 450 inches of rain yearly, making it one of the wettest spots on earth. Kauai hosts over 5,000 plant species, and roughly 90% are found nowhere else. 

If you are a garden lover, you should hit:

  • Allerton Garden: Famous for those giant root formations seen in Jurassic Park (yes, Spielberg loved filming here)
  • Limahuli Garden: Ancient agricultural terraces are still intact after centuries
  • Na Aina Kai: Less famous but includes a cool hedge maze and sculptures

5. Get Schooled in Hawaiian Culture

Kauai keeps Hawaiian traditions alive in ways you won’t find in Waikiki. Skip the tourist traps and try:

  • Smith Family Garden Luau: The imu ceremony (pulling the pig from the underground oven) isn’t just for show – this is how Hawaiians have cooked for centuries.
  • Kamokila Hawaiian Village: A reconstructed traditional village where you can try Hawaiian games and crafts.
  • Hula shows: Many hotels offer free performances. Not just pretty dancing – hula tells stories of Hawaiian history and mythology.

6. Adventures That'll Make Your Friends Back Home Jealous

Kauai’s landscape is a natural playground:

  • Wailua River kayaking: Paddle Hawaii’s only navigable river to Secret Falls. The journey’s as good as the destination.
  • Mountain tubing: Float through old sugar plantation tunnels and canals on inner tubes that can be weirdly fun.
  • Zip lining: Yes, it’s touristy, but flying over those valleys is still pretty awesome.
  • Horseback riding: Western horseback traditions have been part of Hawaiian ranching culture for generations.

7. Chasing Waterfalls

Kauai has waterfalls like Vegas has slot machines – they’re everywhere, and each one promises a payoff:

  • Wailua Falls: The “Fantasy Island” waterfall that’s easy
  • Opaekaa Falls: Another roadside attraction, no hiking required
  • Secret Falls: Requires kayaking and hiking, which keeps the crowds down
  • Waipoo Falls: The big one in Waimea Canyon – you can hike to the top

8. Kid-Friendly Kauai Adventures

These spots will keep both kids and parents happy:

  • Lydgate Beach Park: Rock-enclosed swimming area that’s a natural kiddie pool, plus an enormous community-built playground nearby.
  • Kilohana Plantation: Train rides through orchards, animals to pet, rum tastings for mom and dad.
  • Kauai Mini Golf: Legit educational content about Hawaiian history disguised as mini golf.
  • Surfing lessons: Many beaches offer kid-appropriate instruction. By the end of the lesson, the kids will be standing up.

  • BYO snorkel spots: Bring gear and swim out from the beaches.
  • Sunset at Hanalei Pier: Perfect for budget-conscious romantics.
  • Spouting Horn: Water shooting through lava tubes makes for great photos.

12. Where to Plant Your Beach Towel

Where you stay shapes your whole Kauai experience:

  • North Shore: Lush, dramatic, rainy, and home to the most beautiful beaches. Summer is the best.
  • East Side: Convenient middle ground, more affordable, decent beaches, central location.
  • South Shore: Reliably sunny, good for families, popular with resort lovers.
  • West Side: It is wild, remote, dry, and closest to Waimea Canyon. There are limited options but a unique vibe.

According to accommodation statistics, Kauai has around 9,000 visitor units, which are split evenly between hotels and vacation rentals.

13. Getting Around Without Losing Your Mind

  • Rental car: Pretty much essential unless you’re doing the resort-only thing
  • Island shuttles: Some resorts offer them, but with limited routes
  • Tours with transportation: Let someone else do the driving
  • The Kauai Bus: Works for locals, not great for tourists

14. Surfing and Whale Watching

Surfing is one thing you can never forget in Hawaii. Especially in winter, you can experience heavy swells on Kauai’s North Shore that attract experienced surfers, as these waves can be dangerous for beginners. But it does not mean beginners can’t go to this place, as it gives them a pleasant experience of enjoying the mesmerising scenery on earth.

You can also catch a fleeting sight of whales at Kauai’s shorelines playing, tail slapping, breaching, spyhopping, bubble blowing, and so on. Moreover, while enjoying this boat tour, you can also find amazing spots like beaches (Poʻipū Beach) and scenic spots (Kīlauea Lighthouse), etc.

15. Gardens, Waterfalls, and Lesser Crowds

The best time to explore vibrant gardens, parks, and serene waterfalls is from March to May. As we’ve already discussed, Kauai’s tropical rainforests, valleys, and abundant vegetation have earned it the nickname “The Garden Isle.” You can experience some amazing gardens and landscapes in Kauai, such as:

  • Allerton Garden and McBryde Garden on the South Shore
  • Limahuli Garden in Hāʻena
  • Nā ʻāina Kai Botanical Gardens
  • Smith’s Tropical Paradise Botanical Garden
  • Kauaʻi Coffee Plantation

If you are an adventurous person, then hiking to Hanakapiʻai Falls along the Kalalau Trail and enjoying the dramatic waterfalls is one of the best things to do in Kauai.

16. Hiking, Snorkeling, and Scuba Diving at Kauai

The ideal months for these activities are from June through August. If you want to explore the whole island, hiking is the best way. Some of the best hiking trails are:

  • Awaʻawapuhi Trail
  • Cliff Canyon
  • Black Pipe Trail
  • Kalalau Trail, etc.

While going for this activity, make sure to pack water, sturdy shoes, and other necessary things.

Since this is the summertime, the seas are calm, which makes it perfect for snorkeling and scuba diving. This is a great activity to explore the beauty of the sea. Some of the snorkeling beaches are:

  • Reefs off Kēʻē Beach and Hāʻena Beach Park
  • Anini Beach
  • Lydgate Beach Park
  • Poʻipū Beach State Park.

Whether you are a beginner or experienced, there are a lot of sites for scuba diving where you can discover tropical fish, dolphins, sea turtles, and many more.

17. Kayaking and Enjoying the Local Festivals

Come between September and November to enjoy river kayaking and local festivals. This is one of the unique things to do in Kauai. Enjoy the beautiful surroundings of a thick jungle as you paddle down the Wailua River. There are other rivers, like the Hulēʻia River, Hanalei River, etc. But do hire a good guide for this experience to enjoy it to the fullest.

The Kauai Mokihana Festival uses chant, hula, and music to recognize Hawaiian culture while filling autumn with local events.

18. Kauai’s Helicopter Tours

Since Kauai is an island that cannot be fully explored by car or on foot, helicopter tours are one of the best ways to see this dreamy destination. These tours operate year-round, but during the dry months, you can enjoy them to the maximum due to better visibility.

19. Taste the Best Food from Farmer Markets

In all seasons, you can taste the most delicious food offered by farmers’ markets, providing a sneak peek into local culture. Try apple bananas, lilikoi (passion fruit), fresh poke, or taro chips. Markets you can explore include:

  • The Kilauea Market
  • Kapaa Sunshine Market
  • Hanalei Farmers Market
