5 Simple Ways to Protect Hawaii’s Coral Reefs

Hawaii’s coral reefs are the foundation of our underwater world. They provide shelter for marine life, protect our coastlines, and create the vibrant dive sites we all love. These ecosystems are resilient—but fragile—and every diver and snorkeler plays a role in their protection.

Here are five easy ways you can help keep Hawaii’s reefs healthy:

1. Dive and Snorkel Responsibly

Avoid touching coral or standing on the reef. Even light contact can cause long-term damage. Keep your fins up, maintain good buoyancy, and enjoy the reef with your eyes, not your hands.

2. Use Reef-Safe Sunscreen

Many common sunscreens contain chemicals that harm coral. Choose mineral-based, reef-safe sunscreen, or better yet, wear a rash guard or wetsuit for sun protection.

3. Leave No Trace

Never leave trash behind, especially near the ocean. Small items like bottle caps or food wrappers can be deadly to marine life.

4. Support Responsible Ocean Tourism

Choose dive operators, tours, and accommodations that prioritize sustainability and reef protection. Responsible tourism directly supports conservation.

5. Spread Awareness

Share what you learn with friends and family. The more people understand how reefs work—and why they matter, the better chance we have of protecting them for future generations.

Dive smart. Dive local. Dive with purpose.
