Diamond Head

Hands-down the most popular hike on Oahu

From the smooth slope of its face to its pointed peak, Diamond Head's profile resembles the long brow of an ahi (yellowfin tuna) with its dorsil fin upright, and the Hawaiian name for the crater is Leahi, (lit. the forehead of the ahi). 

Sailors later mistook the calcite crystals in its sparkling sand for jewels and renamed it "Diamond Head." 

By any name this hike offers views of Waikiki to the west and the islands of Molokai, Lanai, and Maui to the east. 

Open daily, 6 a.m. to 6 p.m., last entrance to hike the trail is 4:30 p.m
