The catch: If no dolphins appear from the boat, a repeat of the 4-hour trip still costs half price.
The day
How does the day work?
Poseidon starts with an offshore dolphin search before lunch on the way to the Makaha snorkel stop.
- 1
Board at Waianae
You meet the crew at the harbor's brown two-story building. They explain the day before you board the catamaran.
- 2
Offshore dolphin search
Possible water entries follow the dolphin search. The swimming moves quickly, so this part suits confident swimmers when conditions allow.
- 3
Lunch underway
Your sandwich or wrap comes with chips as the boat travels toward Makaha. A vegetarian choice needs an advance request.
- 4
Makaha water stop
You can snorkel for turtles and reef fish. The 21-foot slide adds water play, with paddleboards also available when conditions allow.
- 5
After the swim
A hot shower lets you rinse off aboard. Hot cocoa or green tea is served after your time in the water.
The 4 hours cover the boat outing through its return to Waianae Small Boat Harbor. Your hotel transfers add time before and after. Water activities aren't guaranteed in every sea condition.
Pickup and meeting point
- Selected hotel stops: Ala Moana Hotel pickup is at 5:20 a.m. on Mahukona Street. Aulani's pickup is at 6:40 a.m., so your own hotel's time matters.
- Drivers: Arrive 30 minutes before departure at the brown two-story building facing the harbor. The address is 85-491 Farrington Highway in Waianae.
- Waiver and lunch: Your booking instructions contain the waiver form. A vegetarian lunch needs a call to the office, so it isn't a choice to leave until boarding.
Before you book
- Choose the dolphin swim only if you're confident. Wildlife sightings and water entries aren't guaranteed.
Fit
Is this tour right for you?
Confident swimmers can use the dolphin portion while a mixed group has reef activities at Makaha. The 21-foot slide adds another reason to join. You need room for 4 hours aboard and earlier hotel pickup. There's room for 70 guests aboard.
For less time aboard, Iruka's speedboat costs from $199 per person for 3 hours and takes ages 5 and up. For snorkeling without dolphin entries, Dolphins and You costs from $183 per adult and doesn't require previous snorkeling experience.
Who it's not for
- Guests focused on dolphin swims who lack swimming confidence
- Travelers with poor cardiovascular health
- Anyone expecting a free repeat after no dolphin sightings
Good to know
Know before you go
The dolphin swim is fast-paced and recommended only for confident swimmers. Infants must sit on an adult's lap aboard. The tour isn't recommended for travelers with poor cardiovascular health, even though other activities are available.
Your default lunch is a turkey sandwich. A different choice needs to be requested by 8 p.m. HST the evening before your tour. You need to call the office for a vegetarian lunch.
Complete the online waiver before your trip. Your mobile booking can cover 1 to 30 travelers and must include an adult. Poseidon's tour limit is 70 guests, so several parties may share your sailing.
Hotel transport can start at 5:20 a.m. at Ala Moana for the 7:30 a.m. sailing. Your exact stop determines the time. Check the assigned pickup instructions instead of using the boat departure as your meeting time.
Ocean conditions and animal behavior affect your chances to enter the water. You aren't promised a dolphin sighting or swim. The later reef stop near Makaha adds another water activity to the planned outing.
You can cancel at least 24 hours before departure for a full refund. Later cancellations don't qualify under the standard policy. Weather or insufficient passenger numbers can also keep the boat from running.

Questions
People also ask
- How much does Iruka's Poseidon dolphin tour cost?
Poseidon starts from $199 per adult for a 4-hour trip with lunch and gear. Selected Waikiki or Ko Olina hotel transport is included. Your photos and wetsuit rental cost extra if you choose those additions.
- What happens if Iruka's Poseidon tour sees no dolphins?
You can rebook for half price if no dolphins are seen from the boat. That's the missed-sighting offer for this 4-hour tour. It doesn't provide a free repeat, and underwater encounters remain dependent on the animals and conditions.
- Is Iruka's Poseidon dolphin swim suitable for beginners?
The offshore dolphin swim is recommended for confident swimmers only because it's fast-paced. The 4-hour outing also includes reef snorkeling near Makaha. A family-friendly boat and its other activities don't remove the swimming requirement for that dolphin portion.
- Where do drivers check in for Iruka's Poseidon tour?
Drivers meet at Waianae Harbor's brown two-story building 30 minutes before the tour. It faces the harbor at 85-491 Farrington Highway. Your selected departure is at 7:30 a.m., so use that time when planning the drive west.
- Does Iruka's Poseidon have a slide and hot shower?
Yes, Poseidon has a 21-foot waterslide and a hot shower for after your swim. Hot cocoa or green tea is also provided. You can use the water activities when conditions allow, with the crew directing the day's entries.
