If you’re honeymooning in Kauai, you’re already winning.
As a professional tourist who’s been to Hawaii 40+ times, I can tell you this island has something the others don’t.
Maybe it’s that 70% of Kauai is completely inaccessible by road, so it still feels wild and untouched. Or maybe it’s just that the island is objectively stunning.
I get asked constantly: what should we actually do on our Kauai honeymoon?
Not the stuff that looks good on Instagram but ends up being a waste of time and money.
The real stuff that makes you turn to your partner and go “okay, this was worth it.”
Here’s what I tell my Hawaii travel consultation clients. And if you want the full download on planning your Kauai trip, I covered all the details in episode 61 of Hawaii Travel Made Easy.
Quick Packing Note
Before we get into the activities, pack reef-safe sunscreen. Hawaii banned the reef-toxic stuff, and TSA will absolutely make you throw out your non-compliant sunscreen at the airport. Trust me on this.
Also bring one nice outfit for dinner (resort casual means you can wear shorts, but put on a collared shirt).
Everything else? Beach casual all day. My husband and I basically lived in swimsuits and cover-ups our last trip.
The Activities (What’s Actually Worth Your Time)
1. Helicopter Tour Over Na Pali Coast
Cost: $250-$450 per person
Time: 45-90 minutes
I’m putting this first because if you only splurge on ONE thing in Kauai, make it this.
70% of Kauai is only accessible by helicopter. That includes the inside of Mt. Waialeale’s crater (the second wettest place on Earth), massive waterfalls, and the full Na Pali Coast from above.
My husband and I did the doors-off flight with Jack Harter. Yes, it was terrifying for the first three minutes. Then it was the most incredible hour of our lives. No window glare in your photos, wind in your face, completely unobstructed views.
Who this is for: Couples who want to see the REAL Kauai, not just the roadside viewpoints. Worth every penny.
Skip if: You’re on a tight budget (this is expensive), you have severe motion sickness, or you’re truly terrified of heights.
Book here: I recommend booking through Get Your Guide because they have good cancellation policies if weather scrubs your flight (which happens).
Companies I trust: Blue Hawaiian (newest helicopters, smoothest ride), Jack Harter (best doors-off experience), Island Helicopters (lowest prices, only company that can land at Jurassic Falls).
Pro tip: Book morning flights. Afternoon = clouds rolling in. Also, couples should sit on opposite sides of the helicopter since they circle the same direction every time.
2. Na Pali Sunset Dinner Sail
Cost: $170-$220 per person
Time: 4-5 hours
We did the Na Pali catamaran tour twice. Once on our honeymoon, again on our fifth anniversary. That should tell you something.
You’ll sail along the 17-mile Na Pali Coast, see sea caves and waterfalls from the water, probably spot spinner dolphins (we saw about 40), and watch the sunset behind those famous cliffs while eating dinner.
Here’s what no one tells you: you will get wet. Wear a swimsuit under your clothes. And take Dramamine 30 minutes before if you’re even slightly prone to seasickness. The open ocean on Kauai’s north shore can get choppy.
The dinner is actually good (not always the case on these tours). Steak, chicken, fish, plus an open bar the whole sail.
Who this is for: The quintessential Kauai honeymoon experience. You haven’t really seen Na Pali unless you’ve seen it from the water.
Skip if: You get seasick easily and refuse to take Dramamine. Seriously, the boat ride can be rough depending on conditions.
Book here: Viator has the Na Pali Sunset Dinner Sail with free cancellation.
Best time: May through September. October through April, the north shore can be too rough to run these tours.
3. Hanalei Day Spa Beachside Couples Massage
Cost: $550-$779 for the Royal Couple package
Time: 2 hours
Okay, this one’s pricey. But you’re on your honeymoon.
They set up massage tables right on the beach in Hanalei, under palm trees, with the sound of waves crashing. You get a full couples massage with the ocean breeze and that perfect Kauai sunshine.
My husband, who normally thinks spa stuff is “not his thing,” will still talk about this massage three years later.
Book way in advance. They only do a few of these a day and they sell out fast.
Who this is for: Couples who want peak honeymoon vibes and are willing to spend for it.
Skip if: You’re on a budget. There are plenty of free romantic beaches if you just want the setting without the $600 massage.
Book directly: Call Hanalei Day Spa at 808-826-6621.
4. Ke’e Beach (Now Requires Reservations)
Cost: $5 per person or $10 per vehicle + $5 per person
Time: Half day
Here’s something that changed: you can no longer just show up at Ke’e Beach. As of 2026, you need advance reservations through gohaena.com.
They limit it to 900 visitors per day now. Book 30 days in advance because spots go fast, especially in summer.
Is it worth the hassle? Absolutely. Ke’e is at the very end of the road on the north shore, with the most ridiculous turquoise water, great snorkeling, and the start of the Kalalau Trail if you want to hike.
My friend’s husband proposed here (before it required reservations). The beach holds a special place for them.
Who this is for: Anyone visiting Kauai. Period.
Skip if: You literally cannot be bothered to make a reservation. But then you’re missing one of Hawaii’s best beaches.
Note: Get there early. Parking fills up even with the reservation system, and the beach gets crowded by mid-morning.
If you’re planning to explore more north shore beaches, check out my complete Hanalei guide.
5. Wailua Falls (The Easy Waterfall)
Cost: Free
Time: 15 minutes
This is the waterfall you see in every Kauai photo. 80 feet tall, double cascade, insanely beautiful.
Best part? You don’t have to hike. You literally drive up, park, walk 50 feet, and there it is.
Go early morning (7-8am) to beat the crowds and catch the best light. The parking lot gets absolutely packed by 10am.
Fair warning: people will tell you about a “trail” to the base of the falls. The county advises against it. Multiple people have died. The trail is steep, muddy, and dangerous. Just enjoy the view from the overlook.
Who this is for: Everyone. It’s a five-minute stop that delivers major wow factor.
Skip if: You’re staying in Poipu and don’t want to drive 40 minutes for a waterfall you see for 10 minutes. (But it’s worth it.)
For more waterfalls that don’t require death-defying hikes, see my post on best Kauai waterfalls.
6. Waimea Canyon Drive at Sunset
Cost: Free (besides parking)
Time: 2-3 hours
The “Grand Canyon of the Pacific” is free to visit and absolutely gorgeous.
Here’s my advice: everyone goes midday when it’s crowded and the light is harsh. Go late afternoon, stay through sunset. The canyon walls turn red and orange, the lighting is incredible for photos, and half the tourists are gone.
Stop at both main lookouts (Waimea Canyon Lookout and Puu Hinahina Lookout). They’re worth the extra few minutes.
Bring layers. It gets surprisingly cool up there once the sun starts going down.
Who this is for: Couples who love scenic drives and epic sunset spots.
Skip if: You’re short on time and would rather spend sunset at the beach. (Valid choice, honestly.)
Note: No reservations needed. No entry fee. Just drive up and enjoy.
7. Private Waterfall Hike (Jurassic Falls Landing)
Cost: $430+ per person
Time: 75 minutes
Only one helicopter company (Island Helicopters) can land at Manawaiopuna Falls, aka Jurassic Falls.
You’ll helicopter into this remote valley, land at the base of the waterfall from the movie, and have the place basically to yourselves for 15-20 minutes.
Is it expensive? Absolutely. Is it worth it? If you can swing it, yes. It’s one of those once-in-a-lifetime honeymoon moments.
Who this is for: Couples who want the ultimate splurge experience and love Jurassic Park.
Skip if: The $430 price tag makes you queasy. The regular helicopter tour is amazing too.
Book here: Island Helicopters
8. Snorkel Tunnels Beach
Cost: Free (or $50-$120 for a guided snorkel tour)
Time: 2-3 hours
Tunnels Beach (officially Makua Beach) has the best snorkeling on Kauai’s north shore.
The reef creates underwater lava tubes and caves. We saw sea turtles, reef sharks (harmless), eels, octopus, and more tropical fish than I could count.
You can snorkel on your own (free) or book a guided tour. Honestly, if you’re comfortable snorkeling, skip the tour and save the money. The reef is obvious and easy to navigate.
Important: The current can be strong. Only snorkel here in summer (May-September) when the water is calm. Winter north shore waves are no joke.
Who this is for: Couples who love snorkeling and want to see turtles.
Skip if: You’re visiting October through April when the water’s too rough. Hit Poipu Beach instead.
Gear: Rent snorkel sets from Snorkel Bob’s.
9. Luau at Luau Kalamaku
Cost: $115-$203 per person depending on seating
Time: 4 hours
Not all luaus are created equal. Some are total tourist traps with mediocre food and one hula dancer who looks bored.
Luau Kalamaku is different. The show actually tells a story (about voyagers traveling from Tahiti to Hawaii), the performers are talented and obviously love what they do, and the production quality is Broadway-level with fire dancers, theatrical lighting, and live music.
The buffet is solid. Standard Hawaiian luau food, nothing revolutionary, but fresh and well-prepared.
Book the Gold Package if you can. Front-row seats make a huge difference for fire dancing.
Runs: Tuesday and Friday evenings only. Books weeks in advance.
Who this is for: Couples who want the full Hawaiian cultural experience and don’t mind spending a bit more for quality.
Skip if: You’ve done multiple luaus on other islands and feel luau’d out.
Book here: Luau Kalamaku through Viator
Note: I covered how to pick a great luau in my Kauai travel guide.
10. Horseback Riding at Princeville Ranch
Cost: $145-$165 per person
Time: 3-4 hours
Princeville Ranch offers rides through private land with ocean views, mountain views, and hidden waterfalls.
The ride itself is beautiful. You’ll pass through pastures, forests, cross streams, all on well-trained horses. Even if you’ve never ridden before, they’ll match you with a calm horse.
Some tours include a stop at a private waterfall where you can swim.
Who this is for: Couples who want a romantic, active experience that’s not a hike or water activity.
Skip if: Either of you is uncomfortable around horses or has back problems (a few hours in the saddle can be rough if you’re not used to it).
Book here: Direct through Princeville Ranch.
11. Poipu Beach at Sunrise
Cost: Free
Time: 1 hour
Not everything romantic costs money.
Poipu Beach at sunrise is stunning. Hardly anyone there, soft morning light, usually calm water. Bring coffee from your hotel and just sit on the beach together.
We did this our last morning in Kauai. Just sat on the beach, watched the sunrise, didn’t say much. One of my favorite honeymoon memories.
Who this is for: Early risers who want a quiet, free romantic moment.
Skip if: You’re not morning people. Sleep in and hit the beach at 9am instead.
12. Kayak the Wailua River to Secret Falls
Cost: $40-$95 per person (self-guided vs guided tour)
Time: 4-5 hours
This is Kauai’s most popular kayak adventure. You paddle up the Wailua River, dock the kayak, hike 20 minutes through bamboo forest to a 100-foot waterfall.
The kayaking is easy (flat river, minimal current). The hike can be muddy. The waterfall is gorgeous and you can swim in the pool.
Pro tip: Go self-guided if you’re comfortable with a kayak and basic navigation. It’s way cheaper and you go at your own pace. Rent from Kayak Kauai or similar.
Who this is for: Active couples who want adventure without intense physical demands.
Skip if: It’s been raining heavily (the river floods and tours get canceled). Or if one of you hates kayaking.
13. Couples Photos with Flytographer
Cost: $295+ for 30-minute session
Time: 30 minutes shoot, delivered within 5 days
Look, I’m not usually the “hire a photographer” person. But for your honeymoon?
Flytographer connects you with local photographers who know all the best spots. You get professional photos of you two actually IN the photos (not just selfies with your arm extended).
We did this at Hanalei Bay. Got 40+ amazing photos we still have printed and framed.
Pro tip: Use my link and save $20: Flytographer
Who this is for: Couples who want real photos from your honeymoon, not just the stuff on your phone.
Skip if: You’re comfortable just doing selfies or asking strangers to take photos.
Book a Hawaii Photo Shoot
Whenever we travel to Hawaii, we almost always book a photo shoot with Flytographer. They are super easy, affordable, AND it guarantees that I’ll have more than just selfies. You can get $20 off if you book through this link.
14. Dinner at a Romantic Restaurant
Here are the three restaurants I send honeymoon couples to:
Merriman’s in Poipu ($$$$) Farm-to-table, ocean views, sunset if you time it right. Reservations open 60 days in advance at midnight HST and they book up fast. Call 808-742-8385.
Oasis on the Beach in Kapaa ($$$) Literally on the beach. Open-air dining with waves crashing 30 feet away. Closed Sunday-Monday. FYI they add a resort fee to the bill. Book on OpenTable.
Bar Acuda in Hanalei ($$$) Tapas-style small plates, more casual vibe, consistently great food. Perfect if you’re staying north shore.
Find more options in my post on romantic Kauai restaurants.
Who this is for: Everyone needs to eat. Might as well make one dinner special.
Skip if: You’re the type who’d rather grab poke and eat it on the beach. (Also valid!)
15. Just Spend a Day at Your Hotel
This sounds ridiculous, but hear me out.
You’re on your honeymoon. You just planned a wedding. You’re probably exhausted.
My husband and I spent one full day at our hotel. Didn’t leave. Slept in, had breakfast on the lanai, hung out at the pool, napped, ordered room service. Best day of the trip.
Don’t try to do everything. Hawaii isn’t going anywhere.
Who this is for: Couples who are honest about needing downtime.
Where to Stay
Your hotel choice matters on Kauai. The island is big enough that where you stay affects what you can easily do.
North Shore (Hanalei/Princeville)
Stay here if: You want dramatic scenery, close to Na Pali adventures, don’t mind rain
Best hotel: 1 Hotel Hanalei Bay on Expedia
South Shore (Poipu)
Stay here if: You want consistent sunshine, calm beaches, easy snorkeling
Best hotel: Grand Hyatt Kauai on Expedia
East Side (Kapaa)
Stay here if: You want central location, lower prices, local vibe
Best hotel: Kauai Beach Resort on Expedia

Practical Stuff
Car Rental: You absolutely need one. Book way in advance. I use Discount Hawaii Car Rental because they compare all the rental companies and find the best price.
Best Time: April-May or September-October. Great weather, fewer crowds, lower prices.
Avoid: December-February (rainy), June-August (crowded and expensive).
FAQ
How many days do you need in Kauai for a honeymoon?
Minimum 5 days. Ideal is 7-10. Don’t try to island hop on your honeymoon. Pick one island and actually relax.
Is Kauai good for a honeymoon?
Yes. Kauai is the most romantic Hawaiian island. Maui gets more honeymoons, but Kauai is better if you want nature, adventure, and fewer crowds.
What should we not miss in Kauai?
Helicopter tour and Na Pali sunset sail. Those two are non-negotiable.
Is Kauai expensive?
Yes. Budget $400-500/day for a couple (hotel, rental car, food, activities). It’s Hawaii. It’s never cheap.
Do we need to book activities in advance?
Absolutely. Especially helicopter tours, luau, and any tour that goes to Na Pali. These sell out weeks in advance in peak season.
Final Thoughts
I know I threw a lot at you. Here’s my honest advice: Pick 3-4 activities from this list that excite both of you. Don’t try to do everything.
The best honeymoon moments aren’t always the big ticket activities. Sometimes it’s the morning you slept in, got poke bowls for lunch, and spent the afternoon at a random beach you found by accident.
That said, do the helicopter tour. Seriously. Do it.
