The Experience

Before You Go

Arrive Early for Parking

Kewalo Basin has limited paid parking; arrive 20–30 minutes early to secure a spot and check in before boarding closes.

Use Reef-Safe Sunscreen

Apply reef-safe sunscreen before boarding to protect coral and avoid greasy lotions that foul mask seals.

Bring a Lightweight Towel

Towels dry quickly on deck and are useful after snorkeling—many operators don’t provide them onboard.

Respect Turtle Space

You may see honu up close but federal law prohibits touching or pursuing them; follow the crew’s distance guidance to avoid fines.

Local Knowledge

Hidden Gems

  • Paddle the calm Ala Moana coastal lanes early morning for a different take on the shore
  • Walk the Kapiʻolani Park paths near Diamond Head for a post-sail picnic and local food trucks

Wildlife

  • Hawaiian green sea turtle (honu)
  • Parrotfish and colorful reef butterflyfish

Conservation Note

Visitors are asked to use reef-safe sunscreen, avoid standing on coral, and never touch or feed marine life to minimize damage to fragile reef ecosystems.

Waikīkī was once a shallow wetland and royal surfing area; the modern waterfront grew with 20th-century tourism and harbor development at Kewalo Basin.

Common Questions

Are sea turtles truly guaranteed?

The operator reports green sea turtle sightings are very common and typically offers a free re-ride if you don’t see honu on your trip, subject to availability and weather.

Do I need to be a strong swimmer to join?

No; the tour is rated easy and provides flotation options, but being comfortable in the water improves your snorkel experience.

What is included in the price?

The trip includes a two-hour sail, snorkel gear (mask, snorkel, fins), snacks, and complimentary local beer, cocktails, and wine onboard.

Is there a dress code or footwear rule?

This is a barefoot cruise—shoes are left at the pier—so wear easy-on footwear and bring a bag for belongings.
