15 Fun Things to Do In Kauai, Hawaii + Highlights Map
Kauai is one of those places that truly takes your breath away. We had seen photos of the emerald cliffs and cascading waterfalls online, but nothing compares to experiencing it in person. We visited the island in July and completely fell in love—with the lush landscapes, the quiet beaches, the warm aloha spirit, and all the unforgettable adventures waiting around every corner.
Known as the “Garden Isle,” Kauai is the oldest and greenest of the Hawaiian Islands, with dramatic natural beauty that feels untouched and wild, and it kind of is, since we heard that only 10% to 20% of the island is accessible by car.

In this guide, we’re sharing everything we experienced and loved during our time on Kauai—from snorkeling with sea turtles to flying over waterfalls in a helicopter. We’ve included a mix of free activities and bucket-list tours, so whether you’re traveling on a budget or ready to splurge, you’ll find something here to add to your itinerary.

Best Time to Visit Kauai
Kauai is beautiful year-round, but each season brings different experiences. Here’s a quick guide:
- January–March: Excellent for whale watching and fewer crowds. Expect more rain on the North Shore—consider the sunnier South Shore.
- April–May: Great weather and fewer tourists. A sweet spot between winter rains and summer crowds.
- June–August: Peak season with warm temperatures and calm ocean conditions. Perfect for water activities, but expect higher prices and more crowds.
- September–October: Less crowded, lower prices, and beautiful weather. Ideal for couples and shoulder-season travelers.
- November–December: Rain begins to return, but it’s still warm. Early December can be quiet before holiday crowds arrive.
15 Best Things to Do on Kauai
1. Explore the Na Pali Coast by Boat or Kayak
One of the most iconic Kauai things to do is to explore the breathtaking Na Pali Coast. Towering sea cliffs, turquoise waters, hidden sea caves, and lush valleys make this coastline one of the most beautiful in the world, in our opinion. We took a morning cruise, and it was the highlight of our trip—complete with dolphins swimming alongside the boat and stunning mountain and water views. More adventurous travelers might prefer cruising along the spectacular coastline aboard a motorized Zodiac raft. Either way, it’s one of the most fun things to do on Kauai.

2. Hike the Kalalau Trail
Starting at Ke’e Beach, this world-famous trail follows the Na Pali Coast with jaw-dropping views of cliffs, ocean, and lush jungle. You can hike the first two miles to Hanakapiai Beach, which is free and doesn’t require a permit. The trail is moderately challenging, with muddy sections and stream crossings, but the payoff is worth it. For serious hikers, the full 11-mile trek to Kalalau Beach requires a camping permit and offers a truly remote and wild experience. Hiking the Kalalau Trail is one of the top things to do on Kauai for couples who enjoy adventure.
3. Take a Helicopter Tour of Kauai
Many parts of Kauai are inaccessible by road, which makes a helicopter tour an incredible way to see the island’s hidden beauty. We flew over the Na Pali Coast, Waimea Canyon, and Manawaiopuna Falls (famously known as Jurassic Falls). The views were absolutely surreal and gave us a true appreciation for the island’s diverse landscapes. A helicopter tour is an unforgettable splurge and one of the best things to do in Kauai for couples or honeymooners.
You can choose a doors-on or off helicopter and we highly recommend the doors-off option if you are brave enough. Just make sure to tie your hair back very securely, or you might end up like me, losing your hair tie and spending two hours untangling your hair after the tour. We splurged on a private tour, and it was 100% amazing, and we highly recommend it! We absolutely loved just being the two of us in the helicopter. This is not a cheap tour either way, but it was a bucket-list item for us.

4. Visit Waimea Canyon
Nicknamed the “Grand Canyon of the Pacific,” Waimea Canyon stretches over 10 miles with depths of up to 3,000 feet. You can spend a day driving through Waimea Canyon Drive, stopping at various lookout points, including the stunning Pu’u Hinahina Lookout. Hiking trails such as the Canyon Trail to Waipo’o Falls offer incredible views and photo ops. Visiting Waimea Canyon is one of the top free things to do on Kauai and a must for nature lovers.
5. Swim at Hanalei Bay
Hanalei Bay is a beautiful beach on the North Shore. The large crescent-shaped bay offers calm waters in the summer, perfect for swimming, paddleboarding, and sunbathing. With the dramatic backdrop of misty green mountains and cascading waterfalls, it’s one of the most picturesque spots on the island. Plus, it’s totally free and family-friendly.
6. Take a Sunset Luau Experience
If you’re looking for a magical way to spend an evening in Kauai, a traditional Hawaiian luau is a must. With live music, graceful hula dancing, and a buffet of island-style dishes, it’s a vibrant and cultural celebration you won’t forget. Many luaus are set against the backdrop of the ocean or tropical gardens, making it a romantic outing for couples or a fun experience for families. We didn’t attend one during our trip, but it’s something we’d definitely plan for next time. Luaus often book out early, especially in the summer, so be sure to reserve your spot ahead of time.

7. Snorkel at Tunnels Beach
Located on the North Shore, Tunnels Beach (Makua Beach) is one of the best snorkeling spots on the island. You can find a variety of tropical fish and even sea turtles! Bring your own gear and go early to snag a parking spot. The beach also offers a stunning view of the Bali Hai cliffs—making it a romantic choice for couples.
8. Zipline Through the Jungle
Looking for an adrenaline rush? Ziplining through Kauai’s rainforest is exhilarating. You soar above valleys and through tree canopies, feeling like you are flying. Some courses even include suspension bridges and rappelling. Ziplining is a great group activity and one of the most fun things to do on Kauai for adventure seekers.

9. Relax at Poipu Beach
On the sunnier south shore, Poipu Beach is perfect for a relaxing day in the sun. The beach has a natural wading pool ideal for kids, great snorkeling, and a chance to spot Hawaiian monk seals. We loved ending the day with shaved ice from a nearby stand and watching the sunset. It’s also a great base for couples staying in South Kauai. We even spotted green sea turtles basking in the sun, which was a magical experience.
10. Visit Wailua Falls
Just a short drive from Lihue, Wailua Falls is one of the most accessible and stunning waterfalls on the island. The twin falls cascade 80 feet and can be viewed from a lookout just off the road. It’s an easy and rewarding stop that doesn’t require any hiking. There are huge signs at the overlook strictly prohibiting hiking down to the base of the falls due to safety concerns and the steep, slippery terrain. Please respect the signage and enjoy the view from above—it’s one of those classic Kauai things to do that’s both easy and memorable.
11. Kayak the Wailua River + Hike to Secret Falls
This combination of kayaking and hiking is a great way to spend a day on the island. You can paddle upriver through a lush jungle setting, dock your kayaks, and hike about a mile to Uluwehi Falls (Secret Falls). The waterfall is incredible, and you can even swim in the pool beneath it. It’s a wonderful way to see a different side of Kauai.

12. Watch the Sunrise at Lydgate Beach Park
Watching the sunrise at Lydgate Beach Park does not disappoint. The east-facing beach is calm and serene in the early morning. Bring coffee or breakfast, walk along the shore, and watch the sky light up in shades of orange and pink. A peaceful and free activity that sets the tone for a perfect day.
13. Explore the Kilauea Lighthouse & Wildlife Refuge
Perched on a bluff on the North Shore, the Kilauea Lighthouse offers panoramic views of the Pacific and is home to many native seabirds. You can spot red-footed boobies and even monk seals down below. If you’re lucky, you might even see whales in the winter. There’s a small entrance fee, but it’s one of the top things to do in Kauai for couples who love wildlife and scenic views. Note that reservations are now required, so make sure you book in advance.

14. Take a Surf Lesson in Hanalei or Poipu
Whether you’re a seasoned surfer or just want to watch from the shore, Hanalei Bay and Poipu are great places to catch the action. Kauai’s laid-back surf culture is fun to experience, and watching surfers ride waves with misty mountains in the background is pretty mesmerizing. If you’re feeling adventurous, surf lessons are available on both shores and are a great way to get out on the water. It’s one of the most iconic and fun things to do on Kauai—whether you’re in the lineup or just cheering from the beach.
