Visit Puʻu o Mahuka Heiau, the largest heiau (religious site or temple) on Oʻahu, covering almost 2 acres. Located a five minute drive from Waimea Valley.
Kaena Point is the westernmost tip of land on the island of Oʻahu. The point can be reached on foot from both the East (via Oʻahu's North Shore / Mokulēʻia) and Southeast (via Waiʻanae Coast). The State of Hawaiʻi has designated the point as a Natural Area Reserve to protect nesting Laysan Albatrosses and wedge-tailed Shearwaters, Hawaiian monk seals. It is roughly a 2 hour hike along the shoreline to the point.
