The Experience

Before You Go

Arrive early for easy boarding

Parking near C Dock is limited; arrive 15–20 minutes early to find the $1/hr lot closest to the pier and check in with the crew.

Use reef-safe sunscreen

Apply reef-safe sunscreen before boarding—do not apply while in the water to protect coral and marine life.

Bring a towel and light layer

A quick swim can be chilly when wet and wind picks up; a microfiber towel and thin hoodie keep you comfortable on the ride back.

Know your swim limits

Snorkeling is in open water with current; stay within your comfort zone and follow crew guidance to avoid fatigue.

Local Knowledge

Hidden Gems

  • Offshore pinnacles near Waikiki that attract dense fish schools—great for snorkeling photos
  • Calm, shallow bays east of Diamond Head that sometimes host resting turtles

Wildlife

  • Humpback whales (Dec–Apr)
  • Green sea turtles (honu)

Conservation Note

Operators follow wildlife viewing rules and encourage reef-safe sunscreen, no-touch policies, and limited disturbance to protected species to reduce human impact.

These shores were shaped by volcanic eruptions and later became important canoe routes and fishpond areas in native Hawaiian life; modern-day whale migration draws international attention each winter.

Common Questions

Where exactly do we meet for departure?

Meet at C Dock in Kewalo Basin Harbor—crew will call your name at the pier entrance; paid parking is available nearby ($1/hr).

Are snorkeling masks and fins provided?

Yes—snorkeling equipment (masks and snorkels; fins may be available) is provided as part of the tour; inform the operator of sizes when booking if possible.

Will we definitely see whales or turtles?

Wildlife sightings are common—humpbacks are most likely Dec–Apr and green sea turtles are frequently seen—but sightings can’t be guaranteed due to natural variability.

Is this tour suitable for non-swimmers or very young children?

The tour is family-friendly and physically easy, but snorkeling requires basic comfort in water; non-swimmers can still enjoy viewing from the boat—life jackets are provided.
