Waikiki Two Tank Guided Scuba Diving Adventure: Certified Diver

The best part of this Oahu outing is its small six-person limit. You are not joining a crowded underwater procession. A PADI Divemaster or instructor can adjust the pace to your skills, which matters when conditions, air use, and comfort vary from one certified diver to the next.

I like the convenient Waikiki meeting point and the fact that tanks, weights, equipment, snacks, and drinks are included. I also like the personal touch shown by Mike, who kept a booking on Easter even when only one diver was scheduled. The main consideration is simple: this is for certified scuba divers only, and the $249 price does not include parking.

Key points to know before booking

• Only six divers per trip: The small group allows more direct attention from the guide.
• Two underwater sessions: You get two tanks during an outing lasting about four hours.
• Waikiki harbor departure: Meet at Ocean Therapy Charters, Front Row Slip 65, in Ala Wai Small Boat Harbor.
• Possible Hawaiian wildlife: Look for green sea turtles, octopus, tropical fish, dolphins, and reef sharks.
• Equipment and refreshments included: Gear, tanks, weights, water, sparkling water, juice, pineapple, and snacks are provided.
• Certified divers only: You must provide your certification agency, level, and certification number.

Two tanks, six divers, and a more personal pace

This is the kind of scuba trip that makes sense when you want underwater time without the feel of a large commercial operation. Ocean Therapy Charters takes a maximum of six divers, so your guide has a realistic chance to keep track of everyone and respond to different comfort levels.

That limit is especially useful if you have not been in the water recently. You are still responsible for your own certification and basic skills, but a smaller group can make the outing feel less hurried. The guide can tailor the pace to your ability instead of pushing the entire group along at one speed.

The trip lasts about four hours and includes two tanks. That gives you two separate chances to explore the southern shore of Oahu, with time between them as the boat moves or the group prepares for the next session. The exact reef or wreck site can depend on sea conditions, safety, and the guide’s judgment, so do not book this expecting one fixed underwater route.

Leaving Ala Wai Small Boat Harbor

The meeting point is Ocean Therapy Charters at 1651 Ala Moana Boulevard, Front Row Slip 65, Honolulu. The boat leaves from Ala Wai Small Boat Harbor, in the heart of Waikiki, a practical choice if you are staying at one of the nearby hotels or resorts.

You will need to arrange your own way to the harbor. Parking is not included and is listed at $1 per hour, so add that cost if you are driving. The meeting point is near public transportation, which can be useful in Waikiki, where walking or transit may be easier than dealing with a rental car.

Before setting out, you must provide your height, weight, and shoe size. These details help the crew prepare your wetsuit, buoyancy control device, and fins. You also need to supply your scuba certification agency, certification level, and certification number. Have that information ready when you book rather than treating it as a last-minute formality.

The boat returns to the same meeting point. That makes the logistics tidy: no separate pickup location, no need to arrange a taxi from another harbor, and no complicated transfer at the end.

What the two underwater sessions are designed to show you

The southern shores of Oahu offer a mix of reef sites and historic shipwrecks. This trip is built around seeing both types of underwater scenery, although the exact places visited are not specified in advance.

Reef sites give you the chance to watch tropical fish move through coral and rock formations. You might also encounter Hawaiian green sea turtles, octopus, dolphins, or reef sharks. These animals are possible sightings, not guarantees, so keep your expectations flexible. The sea decides what appears on the day.

Shipwrecks add a different kind of interest. Instead of looking only at natural reef formations, you may explore the remains of a vessel and see how marine life uses that structure. For many certified divers, wrecks provide a stronger sense of place than a generic reef, but comfort levels vary. If you have limited wreck experience, tell the guide about it before entering the water.

Between the two tanks, the guide can help you prepare for the next session and keep the group organized. The supplied details do not set out a minute-by-minute schedule, so expect a practical half-day outing rather than a tightly scripted attraction with fixed stop times.

Why the small group matters underwater

A maximum of six people is the strongest feature of this outing. Large scuba groups can mean more waiting, more noise, and less room for a guide to notice when someone is uncomfortable or using air at a different rate.

Here, the guide can pay closer attention to your pace and skill level. That does not replace good judgment or certification, but it can make the outing easier to manage. A newer certified diver may appreciate clear guidance, while a more experienced diver may prefer a steady pace without constant crowding.

The personal service also appears in the way Mike handled a solo booking on Easter. He did not cancel when only one diver was scheduled, and that produced a one-on-one outing. You should not assume every date will become a private charter, but the example shows the operator’s willingness to provide individual attention when circumstances allow.

The guide will be a seasoned PADI Divemaster or instructor. No regular guide list is provided, so Mike is the only named guide associated with the available account. If having a particular guide matters to you, ask Ocean Therapy Charters before booking.

Equipment, drinks, and the real value of $249

The price is $249 per person. That is not a budget harbor activity, but it covers the core costs of a guided two-tank scuba outing: dive equipment, tanks, weights, and a professional guide.

You also receive bottled water, sparkling water, juice, pineapple, and snacks during the cruise. Those extras will not transform the price calculation, but they make the half-day outing easier. You do not need to plan a separate snack stop while handling equipment and moving between underwater sessions.

The value depends on what you need. If you own your own equipment and prefer to organize your own shore-based scuba activities, $249 may feel high. If you want a boat-based trip, rental gear, two tanks, professional supervision, and a group capped at six, the price is easier to justify.

Parking is extra at $1 per hour. It is a small charge compared with the activity price, but it belongs in your total budget. The booking includes a mobile ticket, and confirmation is provided at the time of booking.

Wildlife expectations without promises

Hawaiian green sea turtles are one of the biggest draws. You may also see octopus, tropical reef fish, dolphins, or reef sharks. Each sighting depends on location, visibility, season, weather, and animal behavior.

I appreciate that these are presented as possibilities rather than guaranteed attractions. No responsible operator can promise that a turtle will appear on cue or that dolphins will swim beside the boat. Your best approach is to treat wildlife as an added reward, not the sole reason to book.

The reef and wreck setting gives you plenty to watch even when larger animals stay away. Pay attention to the details: fish moving around structures, an octopus blending into its surroundings, and the way a wreck changes the underwater environment. A guide can help you notice more than you would on your own, especially if you are focused on buoyancy, air supply, and navigation.

Fitness, certification, and who should book

You need to be a certified scuba diver. The operator requires your certification agency, level, and certification number, so this is not a trial lesson or a casual first-time swim.

You also need a moderate level of physical fitness. You will handle scuba gear, use fins, enter the water, and complete two sessions. The supplied information does not give a maximum age, medical questionnaire, or detailed water-entry method, so ask the operator directly if you have a medical concern or mobility limitation.

This outing suits certified divers who want:

• A small group instead of a crowded boat
• Two tanks during one half-day activity
• Reef and wreck possibilities along Oahu’s southern shore
• A Waikiki-area departure
• Rental gear included
• A guide who can adjust the pace to the group

It may not suit you if you are not certified, dislike boat-based activities, want a guaranteed animal encounter, or prefer to choose a specific wreck and reef in advance.

If you are not certified, Ocean Therapy Charters offers a separate Discovery SCUBA option in Waikiki. That is the appropriate route for a first scuba experience, not this certified-diver trip.

Weather, cancellations, and planning around your holiday

The outing requires suitable weather. If poor conditions force a cancellation, you can choose another date or receive a full refund. The same choice applies if the minimum number of participants is not reached and the activity is canceled.

For your own cancellation, you can receive a full refund if you cancel at least 24 hours before the start time. Cancellations or changes made inside that window are not refunded or accepted. The cut-off uses local Oahu time, so keep that in mind if you are booking from another time zone.

I would avoid placing this trip on the final morning of your holiday. Weather can change, and a rebooked date is of little use if you are flying home. Give yourself a spare day if scuba plans are a major part of your Oahu visit.

How this compares with a larger boat outing

The key difference is not simply the number of people on the boat. It is how much attention the guide can give each diver.

With six or fewer participants, the group has a better chance of moving at a sensible shared pace. Air consumption, buoyancy control, and comfort in the water can differ widely, even among certified divers. A smaller group reduces the pressure to keep up with a crowd.

The trade-off is that a small operator may have fewer departure options than a large company. The supplied details do not list a full daily schedule, fixed sites, or guaranteed departure times beyond the booked start time. If your Oahu itinerary is tight, confirm availability before arranging other activities.

Practical details to settle before you go

Bring your certification information and make sure the name used for booking matches your identification and certification records. Send your height, weight, and shoe size as requested so the crew can prepare the correct equipment.

Wear practical swimwear beneath your wetsuit and arrive with enough time to find Front Row Slip 65. The exact check-in instructions are not provided, so confirm the recommended arrival time with Ocean Therapy Charters.

You can expect refreshments on the cruise, but do not treat the supplied snacks as a full meal. Have food beforehand if you normally need a substantial breakfast or lunch before physical activity. Bottled water, sparkling water, juice, pineapple, and snacks are included.

The activity ends back at the harbor. You can then return to your hotel, continue around Waikiki, or use public transportation from the same general area.

Should you book this Oahu scuba outing?

Book it if you are certified, want two tanks from Waikiki, and place a high value on a small group. The combination of six or fewer divers, included equipment, PADI guidance, reef and wreck possibilities, and a convenient harbor location gives the $249 price a reasonable case.

I would be especially inclined to book if you have been certified for a while but want a guide to set the pace. Mike’s willingness to operate with a single Easter booking also points to a personal approach, though you should not assume your date will be private.

Skip it if you are not certified, need a guaranteed site or animal sighting, or want the cheapest way into the water. For certified divers who prefer thoughtful supervision over a crowded boat, this is a strong choice for a half-day underwater outing on Oahu.
