Kahaluu Bay holds profound historical and cultural significance, having been populated for at least 500 years and serving as an important royal residence during the 18th and 19th centuries. The entire area around Kahaluu Bay is listed on the National and State Registers of Historic Places as a historic district due to its numerous cultural and historic sites. Key historical features include remnants of a stone breakwater known as Pa o ka menehune, an ancient Hawaiian engineering marvel that once protected the bay. Several heiau (Hawaiian temples) dot the area, including Kuʻemanu Heiau, which overlooked an ancient surf break popular with royalty.

Use Reef-Safe Sunscreen

To protect the delicate coral ecosystem, use mineral-based sunscreens (zinc oxide or titanium dioxide) and avoid chemical sunscreens, which can harm coral. Dispensers for reef-safe sunscreen are often available.
