Sea Turtles (Honu)
Hawaiian green sea turtles, known as honu, are one of the main attractions at Kaneohe Bay. They are frequently spotted near the coral reefs adjacent to the sandbar.
- Sightings are common: Most tours report seeing turtles on the majority of trips
- Turtles are often seen resting on the reef, grazing on algae, or swimming near the surface
- Best chance of spotting them: near the reef areas during the snorkeling portion of your tour
- Captain Bruce specializes in guided turtle reef snorkeling
- Captain Bob’s visits a separate coral reef area where turtles are also common
⚠️ Turtle Etiquette
Hawaiian green sea turtles are a protected species under federal and state law:
- Stay at least 10 feet (3 meters) away at all times
- Never touch, chase, or ride a sea turtle
- Do not block their path to the surface. They need to breathe air
- If a turtle swims toward you, stay still and let it pass
Violating these rules can result in fines up to $100,000 under the Endangered Species Act.
Coral Reef and Fish Species
Kaneohe Bay has one of the largest barrier reef systems in Hawaii. The reef around the sandbar supports a diverse ecosystem.
🐠 Common Fish
- Humuhumunukunukuapuaa (Reef triggerfish): Hawaii’s state fish
- Yellow tang: Bright yellow, found in schools near the reef
- Moorish idol: Elegant black and white striped fish
- Butterflyfish: Several species with distinctive patterns
- Parrotfish: Colorful fish that crunch coral (you can hear them underwater)
- Needlefish: Long, thin fish often seen near the surface
🌊 Snorkeling Conditions
- Water temperature: 74 to 82°F year-round. No wetsuit needed
- Visibility: Usually 15 to 30 feet, best in the morning
- Depth at snorkel areas: 5 to 15 feet over the reef
- Current: Generally mild in the bay
- Difficulty level: Beginner-friendly. Calm, sheltered waters inside the reef
Snorkeling Tips for Beginners
- Practice breathing through your snorkel before getting in the water
- Float face-down and breathe slowly. Do not kick too hard or splash
- Defog your mask with saliva or defog solution before entering the water
- Wear a life jacket if you are not a confident swimmer. All tours provide them
- Stay with the group and near the guide for the best marine life sightings
- Do not touch the coral. It is alive and fragile, and touching it damages the reef
Which Tour Has the Best Snorkeling?
🐢 Captain Bruce
Best for turtle sightings. Guided snorkel at a dedicated turtle reef. Smaller group (max 30) means more personal attention.
🍔 Captain Bob’s
Best overall reef experience. Two-stop tour with dedicated coral reef snorkel stop plus sandbar time. Guided tour with instruction.
🎵 KBOS
Casual bay snorkeling. More focused on water sports (kayak, SUP, banana boat) with snorkeling as one of many activities.
Are There Sharks?
While sharks do exist in Hawaiian waters, encounters at the Kaneohe sandbar are extremely rare. The shallow, enclosed bay environment is not typical shark territory. In over 30 years of tour operations, there have been no shark incidents at the sandbar. The reef area is calm, sheltered, and well within the protected bay.
