Marine Educational Center


Past the park's ticket windows is an excellent educational center run by the University of Hawaiʻi. Interactive, family-friendly displays teach visitors about the unique geology and ecology of the bay. Everyone should watch the informative 12-minute video about environmental precautions before snorkeling. Visit the website for links to a great app that covers snorkeling in the bay.
