Why Kauai?

We did Kauai as the second half of our November 2025 trip — flying in from Oahu for 6 nights at the Grand Hyatt. After the energy and pace of Oahu, Kauai felt like a completely different world. Slower, greener, more dramatic. The kind of place where you genuinely don’t need a packed itinerary to have a great day.

“When we asked the kids which day was their favorite of the entire Hawaii trip, they didn’t hesitate: the doggie day, hands down.”

Na Pali Coast from a catamaran. Waimea Canyon from every lookout. Sea turtles on the beach at Poipu. And a humane society doggie field trip that produced the best hiking we’ve ever done with the boys — six miles, zero complaints.

This was part of a two-island trip. We did Oahu first, then flew inter-island to Kauai. For the full story including combined costs, flight strategy, and the Oahu leg — see our Oahu Guide →

Our 6-Day Itinerary

Day 0 Arrival from Oahu + Coastal Hike

Our quick inter-island flight from Oahu delivered us to Kauai by mid-afternoon. The Grand Hyatt greeted us with an upgrade to an oceanfront room — watching the waves roll in from the lanai instantly melted away any travel fatigue. We didn’t waste the afternoon. The Maha’ulepu Heritage Trail is right near the resort — a beautiful coastal path with stunning ocean views, not too strenuous, perfect for arriving legs. Back at the resort we sampled the pools before calling it an early night.

Day 1 Pure Resort Day — No Agenda

After the pace of Oahu, we designated this our official chill day — and the Grand Hyatt delivered. The pool complex is a water wonderland: multiple pools, a lazy river winding through lush tropical landscaping, and a waterslide the kids couldn’t get enough of. We floated, splashed, napped on lounge chairs. No schedule, no rushing. Sometimes the best vacation days are the ones with nothing on the calendar.

Day 2 Na Pali Coast Catamaran Tour ⭐

Alarm at the crack of dawn for the Kauai Sea Tours catamaran departing at 7:45 AM. We started with snorkeling in crystal-clear water — and a sea turtle glided past us, completely unbothered. Then came the main event: cruising along the Na Pali Coast. I won’t sugarcoat it — the waters were choppy, the ride was bumpy, some of us battled nausea. But the moment those towering emerald cliffs came into view, every uncomfortable moment faded away. Thousands of feet of fluted green rock, hidden beaches, cascading waterfalls. We returned around 2pm and spent the afternoon recovering at the pool.

Day 3 North Shore Scenic Drive

Loaded up the Guide Along app before hitting the road — it narrates as you drive and tells you every worthwhile stop. A genuine game changer for scenic drives. The North Shore delivered around every bend: Wailua Falls (that iconic double-tiered waterfall), Kilauea Lighthouse on a dramatic cliff with sweeping ocean views, Hanalei Pier with its perfect mountain backdrop, and a dozen unplanned stops because every turn was another postcard. For lunch we stopped at Chicken in a Barrel — a local spot on the way to the North Shore that’s worth the detour. A few in our group weren’t feeling adventurous and tried the Thai restaurant nearby instead, which was apparently excellent too.

Day 4 Kauai Humane Society Doggie Field Trip ⭐

Here’s a vacation hack nobody tells you about: the Kauai Humane Society’s Doggie Field Trip program. For $75 you spend the day with an adoptable dog. They give you a backpack with everything — water, treats, waste bags. We kept this as a surprise for Raynuv and Aryan. When they realized we were picking up a furry friend for the day, their faces lit up like Christmas morning. Our dog joined us on the Kilauea Ridge Trail, and something miraculous happened — the kids who usually complain about tired legs halfway through any hike trekked six full miles without a single grumble. They were too busy bonding with their new best friend. When we asked later which day was their favorite of the entire Hawaii trip, both boys answered immediately and without hesitation: the doggie day.

Day 5 Waimea Canyon + Poipu Beach ⭐

Grabbed Subway sandwiches for the road and drove up to Waimea Canyon — the Grand Canyon of the Pacific, and the name is earned. We stopped at every major lookout: Waimea Canyon Lookout where red and green layers of earth create an almost otherworldly landscape, Puu Hinahina for a different angle, and Kalalau Lookout where you can see all the way down to the Na Pali Coast from above. Each stop was genuinely different. We stood in near silence at most of them. On the way back we stopped at Poipu Beach — massive green sea turtles lounging on the sand, completely unfazed by the kids standing right next to them. We snorkeled just off the beach and were rewarded with schools of colorful fish. Best driving day of the whole trip.

Day 6 Last Morning + Evening Flight Home

The Grand Hyatt gave us a late checkout — one final morning at the pool complex. We floated the lazy river one last time, the kids hit the waterslide again, and we sat there reflecting on a week that had given us adventure, wildlife, relaxation, and real family time. Kauai had delivered on every promise. Evening flight home — sun-tanned, memory cards full, hearts full of aloha.

Where We Stayed

🌺

Grand Hyatt Kauai Resort & Spa

One of the best point redemptions we’ve ever made. Oceanfront location, world-class pool complex with lazy river and waterslide, right near Poipu Beach. They upgraded us to an oceanfront room. Rooms run $900+ per night during peak season. We booked 6 nights on 150K Hyatt points at 25K/night, transferred from Chase Ultimate Rewards.

⚠️ Book before May 2026: Grand Hyatt Kauai is moving to Category 8 with dynamic pricing — expect 35–70K points/night after the devaluation. If Kauai is on your list, now is the time.

★ 150K Hyatt points — 6 nights

🏆 Other Points Options on Kauai

🌴

Marriott — Poipu & Princeville

Several Marriott Bonvoy options around Kauai — typically around 50K points/night. More points than Hyatt but Bonvoy is easier to accumulate given the broader card ecosystem.

✓ ~50K Marriott/night
🏨

Hilton Properties

Hilton is present on Kauai but point redemptions run on the pricier side. Worth it if you have a large Hilton balance or Diamond status — just run the math first.

✓ Higher point cost

Getting There

Kauai’s main airport is Lihue Airport (LIH). For us this was the second leg — we flew Detroit to Oahu first, then took the inter-island Southwest flight to Kauai for $332 using a Southwest credit. The return home from Lihue used 44K Avios. Combined with the Oahu outbound (60K Avios), the whole round trip cost 104K Avios total for the family — effectively round-trip Hawaii flights for under 22K points per person.

🎯 Our Avios Flight Strategy

🏆 Finnair Avios was our winner. Turkish Airlines at 10K/way is the holy grail but practically impossible to find for families. Finnair’s fixed award chart had way more availability — 15K Avios for AA flights each way, 11K for Alaska Airlines.
💡 A 20% transfer bonus made it even better. We only needed to transfer ~21,700 points per person to get the 26,000 Avios needed. Effectively under 22K points per person for round-trip Hawaii.
📞 Finnair requires a phone call or chat to book. Can’t do it online. Search availability on BA.com or AA.com first, then call Finnair with your preferred flights ready. Slightly annoying, absolutely worth it.
🧳 Checked luggage was free with AA Gold status — saved $140 for the family across the trip.

💡 Our Top Kauai Tips

🐕 Do the Humane Society Doggie Field Trip. $75, spend the day with an adoptable dog. Our kids hiked 6 miles without a single complaint. Book in advance — slots fill up. This is genuinely one of the most unique things you can do anywhere in Hawaii.
Book the Na Pali catamaran early. Kauai Sea Tours fills up fast. Go in the morning for calmer seas and better light. Bring Dramamine even if you think you don’t need it — the waters are genuinely choppy but the payoff is worth every bump.
📱 Download Guide Along before the North Shore drive. Same app we used in Iceland and Maui — it narrates as you drive and tells you exactly where to stop. Makes a real difference on Kauai’s scenic roads.
🏜️ Hit every lookout at Waimea Canyon. Don’t stop at the first one and call it done. Each gives a completely different perspective. Budget half a day and pair it with Poipu Beach on the way back.
🐢 Poipu Beach for sea turtles — no tour needed. They just show up and lounge on the sand. The snorkeling just offshore is excellent too. One of the most effortless wildlife moments of the whole trip.
🏨 Book Grand Hyatt Kauai before May 2026. Currently 25K Hyatt points/night — moving to dynamic pricing (35–70K range) after devaluation. If Kauai is on your list, lock it in now while the rate is still fixed.
🍗 Chicken in a Barrel for lunch on the North Shore drive. A local institution worth the stop. If your crew wants something different, the Thai restaurant right nearby is a solid alternative.
