This trip was primarily a working trip for AllisonHouse, built around year-end planning and a little time to unwind. My wife came along, and we balanced the workdays with quiet evenings and a few slow mornings. I added two days of diving because I had never been in Hawaiian water before and wasn’t about to miss the chance. Waikiki was the natural choice: easy to reach, reliable operators, and a schedule that fit neatly into the rest of the trip.

The Arrival

The walk from the gate to baggage claim in Honolulu is long, and so is the wait for luggage. Ours took nearly an hour to arrive, but no one seemed impatient. Everyone on the flight had made the same walk and knew the pace of the process.

We were upgraded to an ocean-view room at the Moana Surfrider, which helped set the tone for the week. After settling in, we stretched our legs with a walk through the nearby shopping area. Dinner was simple and relaxed at the beach bar: mai tais, fish tacos, and garlic fries.

The Diving Rhythm

Monday was a setup day. While my wife got ready, I checked over my gear, assembled everything, and made sure it was organized for the next morning. Breakfast at the Veranda was included with Bonvoy status. The food was fine; the water pressure in the room was not.

We spent the late morning exploring Waikiki. The main strip is full of high-end retail, but one block off the path you find smaller cafés and local shops. Lunch at Angry Shrimp was a highlight. I ordered the coconut shrimp plate, and Melissa tried Hawaiian shaved ice for the first time. She decided it beats ice cream.

The afternoon was slow, just the way it should be before a dive day. We sat on the hotel porch in the breeze. She read while I caught up on a few videos. Dinner that night was at Duke’s, a few doors down. It’s tourist-heavy but consistent, and the reservation I made three months earlier paid off with a good table and no wait.

I took one Dramamine with dinner as a precaution, then half a tablet before leaving for the boat the next morning. That routine worked well, so I kept it for the second day.

Conditions and Environment

Both mornings started early. I ate a power bar, drank about 20 ounces of electrolytes, and called an Uber to Pier C at Kewalo Basin Harbor. The ride was about 15 minutes and cost around $13 plus tip. Check-in was 6:45 a.m. for a 7 a.m. departure. Ubers were easy to get at all hours, and parking near the harbor looked limited.

Water temperature held steady at 80 °F, with visibility ranging between 60 and 100 feet. Conditions were calm, and the current was light. Air temperature stayed in the low 80s with light trade winds, comfortable for walking around in the afternoon. My exposure protection was a Bare Exoware top, bottom and hood, which turned out to be perfect for the water temperature.

Kaimana Divers runs a well-organized operation and keeps the groups small. Gabe, the owner, was easy to communicate with by both email and text and responded quickly to questions. They list hotel pickup from Waikiki as available, but I did not try it since I prefer being self-sufficient. Tanks and weights are included in the charter price, and rental gear for other divers on the boat appeared clean and well maintained. Both days the fills were slightly over 3000 psi.

The boat had plenty of shaded space and a small forward cabin suitable for a quick change of clothes if you prefer privacy. Gear was kept in a central bin area, which kept the deck clear and organized. There is a reasonably clean public restroom across the small parking area in the adjacent park, and it’s best to use it before departure. I did not check whether the boat had a head on board, but the trips are short enough that it never became a concern.

Before leaving the harbor, Captain Mattie gave a proper boat briefing, which was good to see. Entries were giant strides from the rear deck, and exits were up a ladder after passing fins up to the crew.

The Moana Surfrider is not a “diver’s hotel” but worked fine. Rinsing small gear in the tub and drying it on the balcony was simple, and the staff didn’t seem to mind. The hotel also has a non-lobby entrance a few dozen feet down from the main doors that leads straight to the elevators, which makes it easier to move gear without walking through the carpeted lobby.

The Standout Dives

Both days of diving were with Instructor Jamie and Captain Mattie.

The first day included two sites. We started with the Sea Tiger, a wreck resting at roughly 100 feet. We hit no-decompression limits near the end of the dive and spent the last few minutes above the wreck letting computers clear. The total bottom time was about 30 minutes. Visibility was good, and we saw turtles, several moray eels, and an octopus hiding deep in the structure.

After a short surface interval, we moved to the Kewalo Pipe, a shallow reef and turtle cleaning station with a maximum depth around 40 feet. Dozens of turtles circled the coral heads while small reef fish picked algae and parasites from their shells. We saw another octopus, a few more moray eels, and plenty of fish life across the reef. It was a calm, steady dive that ran about 45 to 50 minutes.

Back at the dock by 10 a.m., gear was returned to the shop where Jamie handled rinsing and drying. That convenience saved hauling wet equipment back to the hotel.

The second day followed the same rhythm. Several larger dive boats were already operating around the Sea Tiger, but none were overcrowded. When we arrived, three boats were on site. The group before us on our boat hot-dropped, and as we finished prepping, one of the other boats picked up its divers and cleared out. That gave us room to tie in and make a standard descent.

That day it was just Jamie, me, and one Advanced Open Water student. The wreck dive lasted about 30 minutes, similar to the first day. Toward the end, a dark outline of a shark appeared at the edge of visibility before disappearing into the haze.

Surface intervals were relaxed. The crew offered water and snacks, kept gear organized, and maintained an easy pace.

Our second dive was again at the Kewalo Pipe, another 45 to 50 minutes in warm, clear water. The student practiced his DSMB deployment, and I took the chance to do the same. Mine wasn’t smooth, which was a good reminder to practice more often.

I brought my camera on the second day. I never dive with a camera on the first day at a new site. I prefer to learn the operation and the environment first before worrying about photos.

In general, diving around Oahu is less about large coral gardens or schooling fish and more about structure, turtles, and the occasional surprise encounter. Both days were uncrowded and easy, ideal for a simple two-day dive extension.

The Surface Life

Each morning wrapped up early. I was usually back at the hotel by 10 a.m. Lunch after the first dive day was at Hula Grill above Duke’s. The burger and fries were fine, nothing special. We spent the afternoon walking, stopped by a local chocolate shop, and found a shaved-ice stand that lived up to the hype.

Waikiki is built for tourism, but it’s easy to slow the pace if you want to. The Moana Surfrider blends historic character with a modern resort feel, and the porch quickly became our base between outings. The breeze, ocean view, and steady movement of people below made it an easy place to spend time.

Everything we needed was within walking distance. Meals, shopping, and beach access were all close. Evenings were unhurried. The balance between planning sessions, diving, and downtime made the week productive without feeling like work.

One of the most interesting non-diving experiences came from pure chance. While wandering through Waikiki one afternoon, we found Manoa Chocolate, a local craft chocolate company that sources cacao from around Hawai‘i. We had no idea that estate-grown dark chocolate could taste so different from bar to bar. Each had its own flavor profile, much like wine.

We later booked their farm tour just outside Waialua on the North Shore, about an hour’s drive from Waikiki. The tour was led by Katie, who works at the Kamananui cacao research orchard where the tour takes place. It focuses on the agricultural side of cacao, how the trees are grown, maintained, and harvested, rather than the fermenting or roasting process. Those steps are shown briefly as examples, but the emphasis is on cultivation and how growing conditions influence flavor. The tour ends with a full tasting of about a dozen chocolate bars, each presented with notes on flavor and regional character. It was genuine, educational, and low-key. The chocolate was good enough that I signed up for their monthly subscription before I even got home.

On the way to the North Shore we stopped at the Dole Plantation. It’s the exact opposite of Manoa Chocolate. Over-commercialized, packed with pineapple-themed souvenirs, and expensive for what you get. A one-ounce bag of Maui onion chips cost $14, and the food was fast-food quality at best. There’s no real plantation tour; instead you ride a short train with a recorded narration that tells you less than a mediocre Wikipedia article and even includes a pitch for the “official Dole Plantation train song” CD. Unless you absolutely need a stop to stretch your legs, skip it. If you must stop, get a Dole Whip with fresh fruit and move on. There wasn’t even anything worth taking a photo of.

It’s a contrast worth noting. Manoa Chocolate was authentic and worth the drive. The Dole Plantation was not.

Lessons and Takeaways

Short dive segments like this are a reminder that even a couple of well-chosen dives can add a lot to a trip. Hawai‘i offered warm, clear water, friendly operators, and easy access from the city. The dives were not about depth or challenge but about seeing a new region and understanding what local diving in Oahu is really like.

The mix of work, rest, and diving made the week complete. Two days underwater were enough to learn the rhythm of local operations and get a real look at Hawaii’s reef life without turning the trip into a full dive vacation.

Departure Notes

Departure from Honolulu was straightforward. All checked luggage must go through agricultural scanning before you check in. After that, it’s the usual airline counter and TSA process.

Terminal 2 was oddly quiet both on arrival and departure. About half the shops and restaurants were closed, which may explain the lack of crowds. The few options open were limited to Starbucks, fast food, and small market stands. We had hoped to sit down for dinner before our 7 p.m. flight but ended up settling for snacks. Not a disaster, just unexpected for an international gateway airport.

A quick look online afterward suggests this isn’t an isolated issue. Other travelers have reported the same thing, with long stretches of shuttered retail and reduced dining hours loosely tied to flight schedules.

Gear Used

Quick Tips

• Agricultural scan: All checked bags must go through agricultural screening before airline check-in. Lines move quickly but allow extra time.
• Uber timing: About 15 minutes each way between Waikiki and the harbor, average cost $13 plus tip. Parking at the harbor is limited.
• Airport dining: Terminal 2 has limited open shops and restaurants even during the afternoon. Expect reduced hours and few sit-down options.
• Quiet terminals: The airport was calm during both arrival (3 p.m.) and departure (7 p.m.), and online reports suggest this is common.
• Seasonal note: Early November brought warm water and calm seas, a good window before winter surf season affects the North Shore.
• Bring a yoke adapter: If you dive DIN...All tanks were yoke only.
• Tipping: Local practice is about $10–$15 per diver per day for the crew.
• Connectivity: Cell coverage and data service were solid across Waikiki and the harbor.
• Non-diving highlight: Manoa Chocolate farm and tasting tour on the North Shore — worth the drive.
• Skip it: Dole Plantation — commercialized, overpriced, and not worth the stop.
