Are you getting married, Florine?”, “Did you go on honeymoon?”- “Whaaaat? Nooo…

This is pretty much the type of conversation I had on and on, before and after my 2 week trip to Hawaii. The reason? The Hawaiian Archipelago seems such a fantasy destination beyond reach that most people believed it had to be for my big day. For sure, seen from Europe, going right in the middle of the Pacific Ocean is a long, long trip. But then, if you’re an avid and adventurous scuba diver, passionate by incredible nature, wildlife and culture, and you know a thing or two about how to save money even in expensive locations, is it a reason to postpone just for a potential honeymoon even if is a once-in-a-lifetime trip?

I took the opportunity of a business trip to Japan, added a two-week vacation, and put all my British Airways miles into a Tokyo-Kona JAL flight to check if the Aloha State is worth all the fuss and dollars on what look like exciting scuba diving experiences. After all scuba diving is supposed to be one of the fun things to do in Hawaii!

How did I end up skipping Oahu and the world-famous Hawaiian capital of Honolulu and its even more famous Waikiki Beach? First, I had to visit one of my best friends who has lived in Maui for 5 years, and this is from there you can go diving in Maui and its famous Molokini Crater. Regarding Big Island, there was the famous manta night dive and the hope to see lava flowing into the ocean. These were the main arguments to only visit 2 of the 4 main islands for my 2 weeks in Hawaii. I also wanted more time to explore each island, and it was a great way to keep my travel budget under control by avoiding too many expensive inter-island flights.

Map of my Hawaii itinerary

Plan your ultimate scuba diving adventure with the interactive map below. It showcases the main stops in Maui and Big Island and the airports to organise your trip. You will also find some of my favourite dive sites and major nature sites.

Week 1: one-week itinerary in Maui

Hamoa Beach Road to Hana Maui Hawaii

Maui is like the Eden Garden of Hawaii. I have never seen so many diverse breath-taking landscapes concentrated on such a tiny piece of land: from waterfalls flowing in lush bamboo jungles to the apocalyptic colours of Haleakala Volcano.

As a scuba diver you need to be always aware of the altitude and the risk of decompression sickness, so start with the diving and end your stay with the high altitude places like Haleakala Volcano. Even if the island is not so big, to avoid spending too much time on the road,  I recommend staying in the following places:

  • Lahaina, West Maui, for the best diving in Hawaii and an adventurous discovery tour of its coast – 3 days
  • Kihei, Southwest Maui, to add some excellent shore diving and killer sunset on Kihei’s beach. For information, it is cheaper to dive in Molokini Crater from Kihei – 2 days
  • Wailuku or Paia, East Coast, to be close to the start of the Hana Highway and the road to Haleakala National Park – 2 days

If you have a few extra days, you can hop on the only remaining ferry of Hawaii from Lahaina to Lanai. Be aware accommodation is expensive and scarce, but you can still make a day trip as it is only an hour ferry ride.

Best diving in Maui

Just let put it this way, the most impressive diving I’ve done in Hawaii was in Maui. Wouldn’t you feel eager to dive in Molokini, a submerged crater of an ancient volcano, or with hammerhead sharks? What about shore diving with dozens of turtles for only 5 USD? Count half a day for each dive site and please take into account that sometimes the weather can change rapidly so be flexible with your plans.

The dives I couldn’t do because of the weather:

  • Cathedrals I & II, cavern diving in Lanai, from Lahaina
  • Fish Rain, drift dive with hammerhead sharks in Molokai, from Lahaina

Things to do on Maui

The road to Hana

The number one tour in Maui includes 59 bridges, 620 curves, more than 24 waterfalls,  and too many mouth-watering stands to taste juicy dragonfruits and home-baked banana bread. It might be a touristy must-see, but I absolutely loved my day walking in a bamboo forest, swimming in 2 different waterfall pools, and snorkelling at the red sand beach. It is an intense road trip, but you can do it over and over again as there are so many secrets spots to explore. Indications are almost non-existent along the way, so you can drive yourself with preparation and concentration to spot the miles markers, or you can enjoy the ride with other travellers by taking advantage of the free tours organised by hostels in Wailuku and Paia.

Haleakala Volcano National Park

Don’t miss the opportunity to visit this National Park even if the entry to the park is 25 USD for one car (the more you are in the car, the cheaper it gets per person). If you want to see the sunrise from Haleakala Crater, make sure you book your spot in advance, I thought I would have plenty of time at my arrival in Maui, but it was fully booked for the 2 upcoming weeks! It can also be done as one of the free tour organised by the hostels of Wailuku and Paia or with a private guide accredited by the Volcano National Park. Think about taking a warm rain jacket and closed walking shoes before heading to the Park. Don’t be that tourist freezing wrapped in his beach towel because Haleakala is at 3,055 m of altitude.

West Maui tour 

I was lucky to board the Ford Explorer of Delphine from Unique Maui Tours, for a full day of adventures, snorkelling with turtles, hiking through volcanic rocks and splashing in a waterfall pool. Our mini road trip included the ancient petroglyphs of Olowalu, Nakalele Blowhole and heart shape rock, and the delicious “lilikoi” (passionfruit) or coconut cream pies of Aunty Lorraine in Kahakuloa.

Lahaina itself is a delightful old charming harbour where strolling around is pleasant thanks to its historical buildings, its banyan tree square and its quiet beach where wannabe surfers train in the morning with a superb view of Lanai Island.

Sunset drinks at Kihei’s beach 

Join the locals for the most beautiful evening with the sun setting right in the Pacific Ocean. Buy a few Maui Bikini Blonde beers and enjoy the moment at one of the beach parks of Kihei.

Be aware drinking alcohol on a beach in Hawaii is subject to some laws, in doubt, soft drinks work too, only the sunset matters here.

Where to stay on Maui?

Lahaina Beach House, Lahaina

It was love at first sight with the Lahaina Beach House. The owner, Guyton refurbished last year his grandma house into this cosy luxury hostel which is right on the beautiful beach of Lahaina. I stayed there for two nights, but I wished I had a few extra days there. Guyton was kind enough to keep my scuba diving bag before checking in while I was on my West Maui tour. Warmly recommended!

Week 2 : one-week itinerary in Big Island (Hawai’i)

Kalapana Lava Viewing Area Big Island Hawaii

Kona in Big Island was my initial point of arrival from Japan, but as the Ironman triathlon was about to start a couple of days later, I directly took a domestic flight to Maui, as it would mean crowds and higher prices for everything.

So it’s only after a week in Maui that I came back to explore the biggest of the Hawaiian Islands, hence its nickname, which has the confusing real name of Hawaii (so yes there is Hawaii Island in the Hawaiian Archipelago in Hawaii State). If the Kona Manta Night Dive is what primarily attracted me to Big Island, I discovered other diving areas well worth the dip such as lava tubes in the northern Kohala Coast and many impressive nature trails well worth the hike.

My itinerary recommendation for a one-week discovery of Big Island is the following and is going from northwest to southeast:

  • Waikoloa, to spend time diving away from the crowd along the Kohala Coast and go explore the lush jungle and dramatic landscapes of Polulu Valley – 2 days
  • Kailua-Kona, the most touristic area of Big Island with its famous Manta Night Dive, is actually an excellent base to go shore diving and explore the coffee plantations of the region – 3 days
  • Hilo, not really for diving due to its unpredictable wet and windy weather (you can still go snorkelling with turtles though) but as a base to explore the extraordinary Volcano National Park – 2 days

Best diving in Big Island

My favourite dives in Big Island were not what everyone is talking about. While the Manta night dive make the island of Hawaii famous with scuba divers, this a bit further north that I had the most fun underwater. Will you dare to dive too in lava tubes with turtles and dolphins ? Like for Maui, I had the opportunity to go shore diving for just the cost of renting a tank and some weights.

The dives I couldn’t do because of the weather:

  • South Point, from Kailua-Kona
  • Old Kona Airport, from Kailua-Kona

Things to do on Big Island

Polulu Valley

It was one of the most dramatic nature trails I got to hike in Hawaii. It is only 40 minutes driving away from Kohala Divers in Kawaihae so it was a perfect afternoon activity after 2 dives in the morning. Some would say it is not as beautiful as the famous Na Pali Coast in Kaui, but I was delighted by the visit of these impressive cliffs and the lush jungle surrounding the mouth of the Polulu River which lead to a long black sand beach. I recommend at least a light rain jacket and walking shoes (says the girl who forgot them that day).

Find here more information about hiking at Polulu Valley.

Kona Coffee Farms

What to do on a rainy day on Big Island? When I googled the question, it wasn’t obvious at all, so I just figured out that visiting a few coffee farms in the famous area of Kona, around Captain Cook Village, would be a good idea; and it was! Everywhere you can taste for free the different quality of coffee and discover what makes the Kona Coffee so unique and so expensive. I especially loved the visit of an organic farm which used French geese as a way to keep the bugs away and fertilise the plants. Don’t miss the opportunity to stop at the Coffee Shack, to enjoy coffee and macadamia nut pie in a hibiscus flower garden with a great view of Captain Cook Bay.

Pu’uhonua O Honaunau National Historical Park

This historical park helped me with my thirst for learning more about the history of Hawaii and the Polynesian culture. Pu’uhonua means “Refuge”. In case you were breaking the sacred law or in case of war, if you could make it to the holy refuge you would be guaranteed safety and absolution. Most building and statues on display are reconstitution, but I learnt so much about the ancient traditions of the Polynesian tribes that started to colonise Hawaii that I am happy to recommend it. It is the perfect surface interval if you are shore diving at Two Steps.

Learn more about Puuhonua o Honaunau National Historical Park.

The Rainbow Falls & Carlsmith Beach Park

I wouldn’t have expected the chief city of the east coast of Big Island to be the home of so many things to do. If like me, coming from Kailua-Kona in the morning, you don’t have the time to visit the famous Akaka Falls, you have to know that the Rainbow Falls Park is right in the centre of Hilo. Make sure to stop at Ken’s Pancake House before heading to a snorkelling session with turtles at Carlsmith Beach Park. Fun fact: there is spring flowing into the sea hence you can feel the colder freshwater and see a halocline effect, very cool!

The Volcano National Park

Please, be careful, as Haleakala Volcano in Maui, this trip includes going in altitude so make sure to do it at the end of your trip, 24 hours after your last dive. The visit to the Volcano National Park was the pinnacle of my trip to Hawaii. Seeing the lava flowing in the ocean at the viewpoint of Kalapana and the red glow at night of the lava lake in the crater of Kilauea was one of the best things I have seen in my life: our planet Earth at work!

Where to stay on Big Island?

Airbnb room in Waikoloa Village

I couldn’t find any cool hostel on Big Island like on Maui near the places I wanted to go diving. It was especially hard in the north of the island which is famous for the luxury 5* resorts (way beyond my budget, we talk here about hundreds of dollars a night). Hopefully, I found the beautiful house of Barbara with Airbnb only 20 minutes away from Kohala Divers. In Waikoloa Village, a 20-minute drive to Kawaihae Harbour, many owners of lovely villas offer one of their bedrooms to visitors. To get an even better deal, I gave my promotion code to my dive buddy and we got a 35 USD discount, so in the end, we only paid 82,50 USD per night or 41,25 USD per night per person!

Kona Islander Inn in Kailua-Kona

I rented a cute studio apartment at the Kona Islander Inn for the 5 last days of my trip. It wasn’t big (especially the bathroom) but it had everything I needed, including a fully equipped kitchenette I used to cook breakfast and dinner every day (more savings on the trip!), and and and… a swimming pool and a hot tub in a beautiful flower garden just right next to the ocean with plenty of bars to enjoy happy hours at sunset! The cost was about 115 USD per night for my dive buddy and I, including taxes (13,42% always only indicated in the small print). Generally speaking, because Kailua-Kona is the most touristic place on Big Island, there is just more choice, so it was easier to find deals on accommodation.

How to travel to and around the Hawaiian Islands?

Mokulele flight between Maui and Big Island Hawaii

Working on how you will travel to Hawaii and between islands can lead to significant savings once you have all the cards in hands. This why I did my best to reduce to the minimum the number of domestic flights I took during my 2 weeks in Hawaii. Here is all the essential information you should know when preparing for your trip to Hawaii:

  • From Europe, the fastest and cheapest way is via California (Los Angeles or San Francisco). A London-Los Angeles flight takes 12 hours, and from Los Angeles to Maui (Kahului Airport), it takes 6 hours. There are also some great deals that can be found by flying through Texas or Washington State. Make sure to keep track of airlines promotions through social media or newsletters as there are often deals on this route. From the US, you can fly directly to any of the main islands: Oahu, Maui or Big Island.
  • If you are already in Asia, you can find some great offers with direct flights to Honolulu or Kona (but not to Maui) from Tokyo or Osaka. As JAL (Japan Airlines) is in the same alliance than British Airways, I could use my Avios on my return flight Tokyo-Kona. For information, if you don’t mind paying a bit extra and fancy a weekend in Tokyo on your way to Hawaii, I compared the costs and found the flight via Japan was 200€ more expensive than via California.
  • Don’t expect to take ferries to travel between islands: there is only one now which is running between Maui and Lanai. All the other islands are only connected by plane. Basically, you have the choice between Hawaiian Airlines or Mokulele. At the time of booking my Kona-Kahului (Maui) flight, there was a significant price difference between the two. Now I know why, Hawaiian Airlines run normal size planes, while Mokulule uses only 10-seat propeller planes. I am so happy I did this in the end. Not only they accepted my buddy and I on the earlier flight (we had taken a safety margin after the arrival of our plane from Japan), but the view from such a small plane was exceptional: I clearly saw Molokini Crater from the sky. It was an unforgettable experience I highly recommend. With my checked-in bag, return flight was at 170 USD. Because it is not cheap to fly between islands, I decided I would only visit Big Island and Maui, and take the ferry to Lanai (60 USD return), and then take more time to explore each island.
  • There are a few bus options both in Maui and Big Island but they don’t let you travel with big luggage. I took a bus between Maalaea Harbour and Lahaina, the ticket was 2 USD and it was quite frequent and convenient. Alternatively, you can also count on Uber rides, which are easy to find in Hawaii, but for the price of a ride between towns, you can often rent a car for a day.
  • For shore diving or accessing certain sites or scenic roads, renting a car, as usual in the US, is difficult to avoid especially with scuba diving gear in tow. To find a great deal on the rental car I recommend using Cancellation is free so don’t hesitate to check often if you see a better deal as prices are fluctuating and rebook at a better rate at any time. I rented a car for a week on Big Island for 30 USD per day.

When is the best season to travel to Hawaii?

Hibiscus Flower Kona Big Island Hawaii

With the air temperature between 20 and 30°C, and the water temperatures between 24°C to 27°C, you can travel to Hawaii all year-long. “Summer”, from May to the beginning of October, has the hottest and sunniest days. In “winter”, it is just raining a bit more, but it’s also the whale watching season, especially from February to March. In Maui, they usually start to see them in December. Next time, I will go back in the wintertime, because I want to listen to the whale songs while scuba diving!

However, as one of the most touristic places in the world, some periods are more crowded than others. July and August are the peak season while October and November are the quietest months. You have no idea how happy I was to visit Hawaii in October to avoid the crowds, but I found out quite late I would arrive just a few days before the Ironman Triathlon, which brings a lot of people to Big Island. Make sure to check the exact dates if you are travelling to Big Island in October.

As usual in the US, while planning your 2 weeks in Hawaii, try to avoid American holidays:

  • Spring Break (Different period State by State, from mid-March to mid-April)
  • Memorial Day (Last Monday of May)
  • Independence Day (4th of July)
  • Labour Day (1st Monday in September)
  • Xmas holidays from the 24th of December to the 5th of January

  1. The itinerary looks great!
    Thank you for sharing. 😀


  2. I want to dive in hawaii!!


  3. Love your blog. But advising people to avoid paying national parks fees only hurts our planet’s most prized destinations. Support nature, support national parks. ❤️


    1. Thank you for your comment, I think it is quite fair. My point was more that it felt like paying for nothing in my case but I didn’t consider it this way at that time.
