What to Do in Kauai in May: A Month of Fun

 

1. Take to the Skies on a Kauai Air Tour

There are no two ways about it: some of Kauai’s most jaw-dropping scenery just can’t be reached on foot, by car, or even by boat. So if you're here in May and want the full picture—literally—it’s time to take to the skies. We have other articles that go into further depth of what you will see while touring the isle by air, but here’s a brief overview of what you’ll experience.

Whether you opt for a helicopter or a small airplane, flying over the island is next-level. Think emerald valleys, ribboning waterfalls, the towering sea cliffs of the Nā Pali Coast, and crater-filled mountains that feel like scenes from a movie (because, well, they are). You’ll get views of the Manawaiopuna Falls (a.k.a. “Jurassic Falls”), Waimea Canyon (Hawaii’s Grand Canyon), and more places you’ll never forget.

Want the wind in your hair and heart in your throat? Book a doors-off helicopter tour—equal parts thrilling and cinematic. Prefer something more mellow? A cozy plane ride offers panoramic windows and smooth cruising above paradise. Either way, choose a local company. They know the land, the stories, and all the little-known treasures you’d never find on your own.

2. Beach Hop Your Way Around the Island

When wondering what to do in Kauai in May, remember that May means warmer weather, fewer crowds, and just-right ocean temps—so you better believe it’s prime time to beach hop. And Kauai? She’s got beaches for days.

There’s something for everyone. Looking for surf? Want something more chill? Or if you’re craving underwater action, pack your snorkel!

Pro tip: rent a Jeep or 4x4 so you can get to the lesser-known sands— where the sunsets are outrageous and the stars look like diamonds tossed across the sky.

   Charter a Private Plane and Island Hop in Style

If Kauai is just one stop on your Hawaiian journey, consider leveling up your inter-island travel with a private plane charter. Sounds fancy? It is—but it's also a total game-changer.

Forget long TSA lines and airport delays. With a private charter, you set your schedule, hop straight onto the plane, and take off like a boss. Whether you’re dreaming of sipping coffee in Kauai and grabbing lunch on the Big Island, or catching a sunset on Maui after a morning hike in Waimea Canyon, this is how you make the most of your Hawaii trip in style.

Plus, most pilots double as unofficial tour guides. Flying over island chains with a local in the cockpit? Pure magic.

 

4. Treat Yourself to a Garden Tour

May is peak bloom season, and Kauai’s nickname is the Garden Isle, after all. So why not slow down and smell the plumeria?

Check out the Allerton Garden on the South Shore—part of the National Tropical Botanical Garden. It’s home to towering rainforest trees, flowering heliconia, and even movie-famous fig trees (Jurassic Park fans, you’ll recognize them instantly). If you want something more low-key and local, visit Limahuli Garden up north, tucked into a lush valley with mountain and ocean views. It’s both peaceful and powerful, showcasing native Hawaiian plants and the deep cultural roots they carry.

 

5. Hit the Farmer’s Markets (And Eat Like a Local)

There’s no better way to taste Kauai than straight from the source. Farmer’s markets are filled with juicy mangoes, buttery avocados, lilikoʻi (passionfruit), and things you’ve probably never seen before (hello, rambutan!).

Plus, you’ll meet local farmers, artists, and food vendors serving up everything from fresh poke to homemade banana bread. A few great ones to hit in May:

• Kapaʻa Town Market (Wednesdays)
• Hanalei Farmer’s Market (Saturdays)
• Kauaʻi Community Market in Lihue (Saturdays – huge variety)

 

6. Go Whale Spotting (Yep, It’s Still a Thing in Early May)

It may not be on many lists of what to do in Kauai in May because technically whale season starts to wind down in April, but sometimes you can still catch the tail-end (pun intended) of humpback sightings in early May. Grab some binoculars and check out lookout points on the North Shore. You might just spot a mama and baby cruising by.

Even if the whales have left for the season, the views from these spots are 100% worth the trip.

 

7. Just Slow Down and Soak It All In

Last but definitely not least—don’t forget to just be.

Watch the sunrise, sip shave ice, or stroll barefoot through Hanalei Town with nowhere to be. Sit on the sand with a book, swim with the turtles, or do absolutely nothing but breathe in that sweet island air.

May is the perfect time to unplug, slow your pace, and reconnect—with nature, with your travel crew, or with yourself.
