Before entering the park, visitors are required to watch an educational video by the Marine Education Center. The video reminds visitors of the Dos and Don’ts in Hanauma Beach Nature Reserve, including the following:

  • Fishing is not allowed in Hanauma Bay. Marine life is protected in the Reserve, so take only pictures with you!
  • Don’t feed the fish. Doing so will have an overall negative impact on the ecosystem. In addition, anyone caught feeding the fish will be asked to leave or pay a fine.
  • Use safe-reef sunscreen. Many sunscreens contain chemicals that are harmful to the reef and ecosystem. 
  • Don’t step on coral. We want to maintain the lively coral reef ecosystem at Hanauma Bay Nature Reserve, so please avoid stepping on the coral reef, as this can harm or even kill them.
  • Clean up after you eat. There are strategically placed trash bins located throughout the park.
