The interisland flight from Kahului to Kona takes 40 to 55 minutes gate to gate — but door to door it’s closer to 3 to 4 hours once you factor in checkout, airport transit, luggage claim, and picking up a new rental car. That’s the honest math behind any Big Island and Maui combination, and it’s the single most important thing to plan around in a 9-day itinerary. This guide splits the trip across five nights on Maui and four on the Big Island, flying into Kahului (OGG) and departing from Kona (KOA) to avoid backtracking. It’s built for couples and families who want a serious mix of landscapes — Road to Hana, Haleakalā, Volcanoes National Park, and snorkeling at Molokini — without the pacing chaos that comes from spreading too thin.
Nine days is tight for two islands done properly. A minimum of three nights per island is the floor, with four or more being ideal — this itinerary hits four on Maui and four on the Big Island (with one travel day consuming the ninth). Keep that in mind if you’re tempted to add a third island: you’d be cutting one of these down to two nights, which isn’t enough.
Adding another island to a Hawaii trip costs roughly half a day of vacation time — checkout, airport transit, flying, luggage, rental car pickup, and hotel check-in all compound before you’ve seen anything new.
This itinerary is realistic but not relaxed. Road to Hana and Volcanoes National Park are each full-day commitments with zero slack. If one of those days runs long — and Hana almost always does — you’ll feel it the next morning. Build in at least one genuinely slow afternoon on each island, or the trip becomes a list of things you survived rather than enjoyed.

The complete 9-day Big Island and Maui itinerary
Every row below reflects real timing from the research. The transfer day is Day 6 — plan it as a logistics day and nothing more.
| Day | Where You’re Going | What You’re Doing | Time Needed | Key Tip |
|---|---|---|---|---|
| Day 1 | Maui — Kihei/Kaanapali | Arrive OGG, pick up rental car, settle in | Half day after landing | Speedi Shuttle and Roberts Hawaii both serve OGG — reserve before you land if skipping a rental car on arrival day |
| Day 2 | Maui — Molokini and Haleakalā | Snorkeling tour at Molokini Crater; sunset at Haleakalā via Halemau’u Overlook Trail | Full day | Drive from Kaanapali to the Hana Highway start is roughly 90 minutes — don’t try to combine this with Day 3 |
| Day 3 | Maui — North Shore beaches | Mokuleia Bay (Slaughterhouse Beach), Nakalele Blowhole hike, Honolua Bay Access Trail | Full day | Mokuleia Bay has limited parking and no facilities — go early in the morning before it fills |
| Day 4 | Maui — Road to Hana | Ho’okipa Beach Park, Ke’anae Arboretum, Keanae Point Lookout, Aunty Sandy’s, Upper Waikani Falls, Coconut Glen’s, Kaihalulu Red Sand Beach, Wailua Falls, Pipiwai Trail to Waimoku Falls, Seven Sacred Pools | Full day — 10+ hours | Kipahulu Visitor Center is at the far end of the route; Pipiwai Trail adds significant time — decide before you leave whether you’re doing the full loop or turning back at Wailua Falls |
| Day 5 | Maui — Kaanapali recovery day | Kaanapali Beach, snorkeling at Black Rock | Flexible | This is the right day to do nothing — Road to Hana is exhausting; use Day 5 to recover before the interisland travel day |
| Day 6 | Transfer — Maui to Big Island | Fly OGG to KOA, pick up rental car, check in Kona | Half day lost to logistics | Interisland fares typically run $70–$160 per person; rental cars can’t move between islands — budget a separate car for Kona |
| Day 7 | Big Island — Kona coast | Queen’s Bath lava tube at Kiholo State Park Reserve; dinner at Huggo’s On the Rocks | Afternoon and evening | Kiholo State Park Reserve requires a short hike to reach — comfortable shoes, not flip-flops |
| Day 8 | Big Island — Captain Cook and south coast | Captain Cook Monument snorkeling tour (sea caves included); Punalu’u Black Sand Beach; Papakolea Green Sand Beach if time allows | Full day | Papakolea Green Sand Beach requires a 5.6-mile hike round trip — skip it if the Captain Cook tour runs long |
| Day 9 | Big Island — Hawai’i Volcanoes National Park | Kilauea Iki Trail and Crater Rim Trail (3.2-mile moderate loop), Thurston Lava Tube, Holei Sea Arch | Full day | Hilo is 2.5 hours from Kona — depart early; departures from KOA require returning the rental car before your flight |
If you’re departing on Day 9 rather than using it as a full park day, the Volcanoes visit needs to shift to Day 8 and the Captain Cook tour to Day 7. Check your flight time out of KOA before locking in that order.
Days 1–5: Maui in detail
Maui’s geography means the road from Kaanapali to Hana is 90 minutes before the actual drive starts — which is why this itinerary keeps Hana for Day 4, not earlier.
Days 1–2: Arrival, Molokini, and Haleakalā
Landing at Kahului and driving to your accommodation takes a chunk of Day 1 regardless of when the flight arrives. If you’re not renting a car immediately, Speedi Shuttle serves Kahului Airport with advance reservations required — don’t assume ground transport is available on the spot. Day 2 is when the real itinerary starts: a snorkeling tour at Molokini Crater in the morning, then a drive up to Haleakalā for sunset via the Halemau’u Overlook Trail. These two are on opposite sides of the island in terms of feel — one at sea level, one at elevation — and they don’t overlap logistically, which makes the pairing work.
The Haleakalā drive is not quick. Allow enough time to be at the overlook well before the sun drops, and bring a layer — temperatures at elevation are significantly cooler than the coast.
Day 3: North Shore beaches
Mokuleia Bay — sometimes called Slaughterhouse Beach — sits on the northwest tip of Maui and has limited parking with no bathroom facilities. Go in the morning before the lot fills. From there, the Nakalele Blowhole is a short drive north, and Honolua Bay Access Trail continues the same coastal loop. These three stops form a natural north-shore morning without major driving between them.
If the surf is heavy on the north shore, Mokuleia Bay’s water can be rougher than it looks from the road. It’s worth checking conditions before committing to swimming there — Honolua Bay is often calmer and has good snorkeling when conditions allow.
At Mokuleia Bay, parking fills quickly on weekends and the lot has no shade or facilities. Mid-week morning arrivals have a clear advantage over weekend afternoon visits.
Day 4: Road to Hana — the full route
This is the day that will define the Maui portion of your trip, and it needs to be treated as a 10-plus-hour commitment. The research-documented stops on the full route include Ho’okipa Beach Park, Ke’anae Arboretum with its Rainbow Eucalyptus trees, Keanae Point Lookout, Aunty Sandy’s banana bread stand, Upper Waikani Falls (Three Bears), Coconut Glen’s, Kaihalulu Red Sand Beach, Wailua Falls, and — at the far end — the Kipahulu Visitor Center with the Pipiwai Trail, Bamboo Forest, Waimoku Falls, and the Seven Sacred Pools.
The Pipiwai Trail to Waimoku Falls is a meaningful add-on that takes serious extra time. If you’re not starting the drive before 7 a.m., consider stopping at Wailua Falls and turning back rather than pushing to Kipahulu — arriving at the Seven Sacred Pools after 4 p.m. leaves little daylight buffer for the return drive. The road back from Hana is the same road; there’s no shortcut.
Day 5: Kaanapali rest day
Kaanapali Beach and the Black Rock snorkeling area are directly accessible from most Kaanapali accommodations — no driving required. After Road to Hana, a low-movement day here isn’t optional for most travelers; it’s recovery. This is also the day to pack for the interisland move and confirm your rental car return time for the next morning.
Don’t underestimate how tired you’ll be after Day 4. Lily and Ethan can handle a beach day without much structure — but even for adults, trying to add another activity on Day 5 consistently creates a flat, unfocused afternoon rather than a productive one.
Days 6–9: Big Island in detail
The Big Island’s west-to-southeast axis means two very different landscapes within the same island — and the drive between them is the planning constraint everything else hangs on.
Day 6: The transfer day
Interisland flights between Maui and the Big Island gate to gate are 40 to 55 minutes, but the full process typically takes 3 to 4 hours when you account for checkout, airport time, landing, luggage, and picking up a new rental car in Kona. Rental cars cannot travel between islands, so you’re starting a fresh booking at KOA. Budget $70 to $130 per day for the Big Island car separately from what you paid on Maui.
The afternoon after landing is enough for a short orientation drive around Kailua-Kona. Don’t plan anything demanding on Day 6. If your flight arrives early enough, Kiholo State Park Reserve — where the Queen’s Bath lava tube is located — is a reasonable first stop before dinner at Huggo’s On the Rocks.
Day 7: Kona coast and Captain Cook
The Captain Cook Monument snorkeling tour includes sea caves and covers some of the Big Island’s clearest coastal water. This is a structured half-day activity that typically runs in the morning — confirm the departure time when booking. The afternoon can extend toward the south coast, with Punalu’u Black Sand Beach as a natural stop along the way toward Volcanoes National Park territory. Papakolea Green Sand Beach requires a 5.6-mile round-trip hike to reach — it’s worth the effort on its own day but cuts deeply into time if tacked onto a Captain Cook tour day.
If the Captain Cook tour runs long or you want to prioritize Papakolea, move Punalu’u to the Volcanoes day instead. The south coast stops sequence naturally from Kona toward the park regardless of which order you hit them.
The drive from Kona to Hawai’i Volcanoes National Park via Hilo is roughly 2.5 hours. Stacking this with a morning Captain Cook tour and an afternoon at Papakolea leaves almost no buffer — one delay anywhere collapses the rest of the day.
Days 8–9: Hawai’i Volcanoes National Park
The Kilauea Iki Trail and Crater Rim Trail form a 3.2-mile moderate loop that covers the core of what Volcanoes National Park offers on foot. Thurston Lava Tube and Holei Sea Arch are accessible by car along the same route. Give this a full day — arriving early from Kona means starting the hike before mid-morning heat and crowds build.
If Day 9 is your departure day, Volcanoes needs to happen on Day 8 with an early start. The return drive to KOA for a late-afternoon flight is tight from the park — build in more time than you think you need, and remember that the rental car needs to be returned before the terminal drop-off window closes.

For water activities across both islands — Molokini, Captain Cook snorkeling, Kaanapali’s Black Rock — a waterproof action camera handles the conditions far better than a phone. A waterproof action camera with 360° stabilization rated to depth works for both open snorkeling and lava tube environments without needing a separate housing.
Logistics: flights, cars, and timing the move
Getting between islands
There are no ferry services between Maui and the Big Island — the only connection is by air. Inter-island flights start around $45 and run roughly 45 minutes, though rates vary significantly by carrier and booking window. Southwest charges for checked bags on Basic and Choice fares ($35 for the first bag, $45 for the second), which affects how you pack for a two-island trip with two separate rental cars.
An open-jaw flight structure — flying into OGG and departing from KOA — avoids a redundant return leg and is the most logical approach for this itinerary.
| Transfer detail | Maui (OGG) | Big Island (KOA) |
|---|---|---|
| Airport shuttle option | Roberts Hawaii, Speedi Shuttle (advance booking required) | No shuttle listed — rental car recommended |
| Rental car daily rate | Around $70–$130/day | Around $70–$130/day (separate booking) |
| Drive to key sites | 90 min from Kaanapali to Hana Highway start | 2.5 hours from Kona to Volcanoes via Hilo |
| Nights recommended | 4 nights minimum | 4 nights minimum |
Booking windows and pacing risks
The Molokini snorkeling tour and the Captain Cook Monument tour both require advance booking — these fill up, and the morning departure slots go first. Lock in both before you finalize the rest of the daily schedule around them, since their departure times determine what else fits that day.
- An open-jaw flight (OGG in, KOA out) eliminates backtracking and is the most efficient structure for this itinerary — book it before anything else.
- Rental cars are island-specific; you need two separate bookings, two separate insurance decisions, and two separate return times — don’t treat them as one continuous rental.
- Road to Hana and Volcanoes National Park are both full-day commitments with no realistic way to compress them — every other day in the itinerary needs to accommodate the fatigue those two generate.
Questions about combining Big Island and Maui in 9 days
Is 9 days enough for both Big Island and Maui?
Barely, and only if you accept that one day will be consumed by the interisland transfer. You end up with roughly four usable days on each island, which covers the major sites without much margin. If Road to Hana or Volcanoes takes longer than planned — and both often do — you’ll feel that lost time elsewhere.
If you can extend to 10 or 11 days, the buffer makes a real difference. A 10-day two-island plan gives each island five nights and removes the pressure from both major driving days.
Should I do Maui or Big Island first?
Maui first makes more logistical sense for this itinerary. You fly into OGG, do Road to Hana and Haleakalā while fresh, then transfer to the Big Island and depart from KOA — no backtracking. Starting on the Big Island works too, but departing from OGG means an extra flight leg back toward Maui.
The open-jaw structure (in OGG, out KOA) is the cleaner option for most travelers and typically doesn’t cost more than a round-trip through one airport.
What’s the most common mistake on Road to Hana?
Starting too late. The full route to Kipahulu and the Seven Sacred Pools takes 10-plus hours — leaving Kaanapali after 8 a.m. means arriving at the far end in fading light with a long return drive still ahead. Most people who say Road to Hana was disappointing simply ran out of time before reaching the best stops at the eastern end.
The straightforward fix: treat it as an all-day commitment and build Day 5 as a genuine rest day to absorb whatever Road to Hana takes out of you.
Is the Papakolea Green Sand Beach worth it on this itinerary?
Only if you dedicate specific time to it. The access hike is 5.6 miles round trip, which takes roughly 2 to 3 hours and isn’t compatible with a day that also includes a snorkeling tour and the south coast drive. If green sand is a priority, replace the Captain Cook tour day with a dedicated south coast day instead of stacking both.
If you’re short on time, Punalu’u Black Sand Beach is roadside-accessible and takes under an hour — it’s the easier version of the south coast experience and doesn’t require the same time commitment.
Do I need a rental car on both islands?
Yes. Rental cars cannot move between islands, so you need a separate booking for each. Public transport on both Maui and the Big Island is limited outside of the immediate resort corridors — without a car, Road to Hana, Haleakalā, and Volcanoes National Park are all inaccessible or impractical. Budget the rental car as a fixed cost for both islands from the start.
The Maui and Big Island combination works as a 9-day trip because the two islands complement each other in ways that don’t overlap — lush coastal drives and volcanic peaks on one side, active lava fields and Kona snorkeling on the other. Couples and active families who want serious experiences on both islands without a third-island detour will find this structure holds together well. The transfer day is the price of admission; plan it as a logistics day, not a lost one. For anyone considering whether to add Oahu to the mix, the honest read is that 9 days isn’t enough to do all three justice — you’d be giving Oahu two nights, which barely scratches the surface. If this was useful, you might also enjoy reading the family-focused Hawaii itinerary that maps pacing across different island combinations.
