Important Information: Wearing reef-safe sunscreen is one small act with a big impact—it’s part of your kuleana (responsibility) to care for the ocean. (Oxybenzone and Octinoxate are prohibited.)
It is illegal to feed, crowd, touch, and harrass the Marine Life, whether they are on shore or you are in the ocean. Fines for touching or harassing can be up to $10,000 (State) to $100,000 (Federal), and even include jail time. Specific penalties can vary depending on the severity of the violation and whether federal or state laws are involved (Hawaii State Law and Federally – The Endangered Species Act and Marine Mammal Protection Act.)
You are entering the Ocean of your own free will. Not every place will have lifeguards. Make sure you are aware of the water conditions before you go in, never turn your back on the ocean, and know your own skill level. Secluded beaches are not your friend, however you should never risk your life or any one else’s.
While we love our Manō (sharks) and know that they are not all dangerous, some of them are. Remember you are a visitor in their home, and just as you are curious to see the Marine Life, they too are curious creatures. Make sure you are aware of your surroundings, do your research ahead of time, read signs, pop your head up, and go with a friend. In the event you see a shark, remember not to panic or thrash around, and avoid sudden movements that might attract the shark further, and calmly exit the water. If the shark approaches, try to back away slowly while maintaining eye contact, but don’t turn your back. If attacked, defend yourself by hitting the shark’s sensitive areas like the eyes, gills, or snout.
