Just a short boat ride from Waikiki Beach lies Turtle Canyon, a hidden underwater paradise where green sea turtles gather to be cleaned by reef fish. This is one of the most reliable spots on Oahu to snorkel alongside sea turtles in their natural habitat—an unforgettable experience for all ages.
Why Turtle Canyon Is Special
Turtle Canyon isn’t a beach and you can’t access it by foot. It’s a shallow offshore reef visited exclusively by boat. Turtles congregate here regularly, making it one of the few places in Hawaii where sightings are almost guaranteed. Thanks to the protected reef and professional guides, it’s a safe and beginner-friendly snorkeling destination with crystal-clear water, vibrant marine life, and minimal current.
What to Expect
Turtle Sightings
Turtle Canyon is a cleaning station—turtles come here daily to let fish nibble algae off their shells.
Boat Access Only
You’ll depart from Waikiki or Kewalo Basin Harbor on a catamaran or snorkeling boat. Most tours include snorkel gear and safety equipment.
Calm & Shallow Waters
The area is protected from strong currents, with depths ranging from 10 to 20 feet—great visibility and ideal for beginner snorkelers.
Snorkeling Tips for Turtle Canyon
Snorkeling at Turtle Canyon is an incredible experience, but a few smart tips can make your adventure safer, more enjoyable, and eco-friendly:
Choose a Morning Tour
Turtle Canyon waters are typically calmest in the morning. Early tours offer better visibility, fewer crowds, and more active marine life—including turtles.
Don’t Touch the Turtles
Under Hawaii and federal law, it’s illegal to touch or harass sea turtles. Stay at least 10 feet (3 meters) away, and let them swim at their own pace.
Practice Passive Snorkeling
Stay calm and float. Avoid chasing marine animals or splashing, which can scare them away or stir up sediment. Keep your fins off the reef and swim slowly with your arms tucked in.
Use Reef-Safe Sunscreen
Hawaii bans sunscreens containing oxybenzone and octinoxate to protect coral reefs. Pack a mineral-based, reef-safe sunscreen—and apply it at least 15 minutes before entering the water.
Wear Bright Colors or a Snorkel Buoy
To stay visible to your group or nearby boats, consider wearing a neon rash guard or towing a small surface marker buoy—especially if you’re not with a guided tour.
Listen to Your Guides
If you’re on a tour, follow all instructions from the captain and guides. They know the currents, wildlife behavior, and how to keep everyone safe.
