Diving Honolulu Reefs: Whitetip Shark & Green Turtles

Article by Ken Goetz, SCUBA diving instructor, Rainbow Scuba Hawaii on

Dreaming of an easy, unforgettable first SCUBA dive in Honolulu? Rainbow Scuba Hawaii makes it simple. We depart Kewalo Basin—just minutes from Waikiki—for a smooth boat ride, a friendly safety briefing, and a relaxed giant-stride entry onto a living coral reef. Typical conditions are gentle: 30–45 ft (9–14 m) depths, 60–100 ft visibility, and mild current. Your guide manages buoyancy and navigation so you can focus on the magic—reef fish swirling around coral heads, a stealthy whitetip reef shark tucked beneath a ledge, and two Hawaiian green sea turtles gliding by. If you’re new to Oahu diving, this tour is built for comfort, safety, and big smiles from surface to surface.

Conditions & Safety Flow

Before we anchor at Horseshoe Reef or a similar protected site, your instructor reviews the site map, hand signals, and equalization tips. Gear is fitted on the ride out; masks are defogged, weight checks are quick, and we confirm buddy teams. Entry is a stable giant stride (or backroll, depending on position), followed by a surface OK and an easy descent along the mooring line. On the bottom, we settle neutrally buoyant over sand patches so beginners can relax before touring the reef. You’ll practice slow fin kicks, keep hands close, and follow the guide’s no-touch rule to protect coral and wildlife.

Expect a mellow 35–40 minute profile with a conservative max depth around 40 ft. We avoid surgey zones, watch for boat traffic, and ascend with a safety stop. If you’re nervous, let us know—we’re experts at first-time dives in Honolulu and will tailor the pace so you finish confident and grinning.

What You’ll See on Honolulu’s Coral Reefs

Whitetip Reef Shark Behavior

Whitetip reef sharks are a highlight on Oahu. They rest under ledges during daylight and are typically calm around divers. We brief everyone to approach slowly, keep hands close, and let the shark set the distance; you’ll often get a great look at the distinct white-tipped dorsal and tail fins as it breathes rhythmically on the bottom.

Hawaiian Green Turtles, Up Close

Honu—the Hawaiian green sea turtle—frequent these reefs to feed and visit cleaning stations. The best encounters happen when we stop and float; the turtle chooses whether to cruise by. Give at least 10 ft of space, never touch, and stay off the bottom to protect coral. Keep your camera ready near coral heads where cleaners work.

Planning Tips

Morning trips offer calmer seas and clearer water. Wear a light rash guard under the 3 mm shorty, bring reef-safe sunscreen for topside only, and consider a non-drowsy seasickness remedy before boarding. Parking is available at Kewalo Basin; arrive 20 minutes early to meet your guide and sign waivers.
