The Experience

Before You Go

Use reef-safe sunscreen

Hawaii prohibits oxybenzone-containing sunscreens; bring reef-safe sunscreen to protect coral and marine life.

Arrive early for parking

Paid parking at Kewalo Basin is closest to C Dock and fills quickly—plan to arrive 20–30 minutes before departure.

Prep for seasickness

If you get motion sick, take a preventative tablet an hour before departure; ginger and acupressure bands can help.

Respect wildlife distance

Never touch or chase turtles and dolphins—stay quiet and let animals approach on their terms.

Local Knowledge

Hidden Gems

  • View of Kakaako’s shoreline art from the water — murals read differently from sea level
  • Ala Moana’s offshore reefs near Magic Island often hold calmer snorkeling pockets outside peak hours

Wildlife

  • Green sea turtle (honu)
  • Spinner dolphins

Conservation Note

Anchoring is managed to avoid reef damage—follow the captain’s instructions, use reef-safe sunscreen, and never touch marine life to reduce local impacts.

Diamond Head (Leahi) is a volcanic tuff cone formed during Oahu’s Honolulu Volcanics; Kewalo Basin has long served as a small-boat harbor tied to the island’s fishing and commercial history.
