This is a sacred place that remains meaningful to Hawaiians, so keep to the paths and leave stones and offerings undisturbed.
A heiau above Waimea Bay
Puʻu o Mahuka Heiau is the largest heiau on Oʻahu. Built in the 1600s, it was a significant religious site in the period before contact. Heiau are Hawaiian temples associated with practices including prayer, offerings and ceremonies. Their purposes differed, and the available information does not identify every ritual held at this site.
The hilltop setting looks across Waimea Bay and Waimea Valley. The stone walls divide the heiau into three enclosures, and the grounds cover more than two acres. The surviving structures are ruins, but the scale of the site is clear as you walk around them.
Walking the site
A short path circles the ruins, with signs that provide information about Hawaiian culture and the heiau. Side paths lead to overlooks above the bay and valley. Allow time to pause at these viewpoints as well as to read the signs.
The drive up is along a winding road. A parking lot is available at the site. Keep to the designated paths and follow posted guidance; do not walk on the stone structures, touch the temple walls or move anything left at the site.
Respecting a sacred place
Puʻu o Mahuka Heiau remains sacred to Hawaiians, and offerings are still left here. Quiet, respectful conduct helps protect the site and recognizes its continuing cultural significance. Leave offerings and stones where they are, and do not remove anything.
There is no water or restroom at the site, so bring what you need before arriving. An early visit can give you a quieter walk around the ruins and time at the overlooks.
