Kealakekua Bay (Captain Cook Monument) Snorkel Adventure

Yes! Everyone who enters the water needs to be able to comfortably swim a minimum of 25 yards (23 m) in the ocean without a life jacket.

Yes. We provide foam noodles to all guests, and life jackets by request.

We require a minimum of 6 guests to run all tours. If we do not reach our minimum, we will offer to rebook you to a different tour or issue a full refund. Alternatively, you can purchase additional tickets to reach the minimum of 6 guests, which will ensure the trip can run.

Snorkelers at Kealakekua Bay can see Hawaiian green sea turtles (honu), a variety of reef fish including butterflyfish, parrotfish, and surgeonfish, as well as schools of tropical fish. The bay is also home to rays, occasional reef sharks, and spinner dolphins. In the winter months, humpback whales may be visible from the surface. The coral reefs provide shelter and food for a diverse range of marine life.

Common sunscreens contain chemicals that can harm coral reefs, as the particles are small enough to be absorbed by corals, causing toxicity and coral bleaching. Reef-friendly sunscreens are formulated without these harmful chemicals. Reef-SAFE sunscreens go a step further by using non-nano particles, which are too large for corals to ingest, helping to preserve marine ecosystems. 

Please avoid sunscreens with oxybenzone, octinoxate, and parabens. Consider wearing sun-protective clothing, like long-sleeve rash guards, as an alternative to sunscreen. If you choose a mineral-based sunscreen, ensure it is labeled ‘non-nano.’

TripOutside recommends knowing how to swim before snorkeling, but participation is ultimately up to you and the tour operator's discretion.

• Check ocean conditions and only snorkel at lifeguarded beaches. The chance of rescue is much higher with trained lifeguards present.
• Never snorkel alone. Always bring a buddy. Beginners should consider booking a guided tour.
• Rest after flying. Flying can dehydrate and exhaust you—give your body at least a day to acclimate before snorkeling.
• Test your gear on land or in a pool first. Make sure your mask fits snugly, you can breathe through the snorkel, and you know how to clear water if needed.
• Practice with fins. You should be able to scissor kick while swimming. Avoid doggie paddling—it won’t get you far.
• Don’t wear fins on land. Walk into the water, get past the waves, then put your fins on. Remove them before exiting.
• Take it slow. Breathe calmly, relax, and avoid overexertion to keep your heart rate low.
• Know your limits. If you’re feeling tired, anxious, or unsure about conditions, skip the snorkel session. Panic in the water is dangerous.
• Stay aware of currents and tides. Even experienced swimmers can get pulled out. Know how to identify rip currents and how to escape them (swim parallel to shore).

You can snorkel with a beard or mustache but it can prevent a tight seal between the mask and your face, which may cause water to leak in. It is often recommended to shave at least your mustache before diving. If you’d prefer not to shave your mustache, please bring petroleum jelly or chapstick with you. If you coat your mustache in that chapstick or jelly, it may be able to seal and prevent water from getting in.

Glasses cannot be worn while snorkeling, but contacts are perfectly fine and recommended for the best experience. Prescription masks are not available for rent, but you are welcome to bring your own.

Additionally, there is an automatic correction effect that occurs underwater due to light refraction, making things appear clearer, but contacts or a personal prescription mask will provide the best visibility.
