At the base of the bay near Nāpōʻopoʻo, you’ll find the remains of Hikiau Heiau, an ancient Hawaiian ceremonial temple. The heiau sits atop a large stone platform and was used for religious and royal ceremonies. Although it has been damaged and restored over time due to waves and tsunamis, the site retains a deep spiritual significance.
Important: Visitors must not walk on or disturb the heiau out of respect for Hawaiian traditions and cultural practices.

Kayakers must follow strict regulations to protect the fragile environment and cultural sites. Landing is only allowed in designated areas.
