Keaīwa Heiau

Much of this area was replanted by foresters in the late 1920s. The lemon eucalyptus trees give the air a light citrus fragrance. Stands of Norfolk Island pine trees mark the lower end of the trail. Look for the native koa and ohi’a trees as you reach Pu’u Uau, the high point about midway along the length of the trail. You might also see remnants of a B-24 bomber that crashed in 1944.

The name Keaiwa has been translated as mysterious or incomprehensible. Perhaps, this name refers to the fact that one could not explain the powers of the kahuna and the herbs used in healing.

It is unknown when this heiau was built but one source suggests that it was constructed in the 16th Century by Kakuhihewa, an ali’i (chief) of Oʻahu, and his kahuna Keaiwa. The 4-foot high stacked rock wall encloses the sacred area that measures 100 by 160 feet. Within the enclosure was a halau (large thatched structure) built for the master kahuna to store the medicinal implements and train the students. Other features might include hale (small thatched structure) and a puholoholo (steam bath).
