Pu'u Ohia (Mount Tantalus) Professional Guide
Detailed Trail Description from our Guidebook
"Pu’u Ohia is the Hawaiian name for Mount Tantalus, the high point on the edge of a volcanic cinder cone. The view from the summit is one of the finest, taking in Diamond Head, Pearl Harbor, the Wai’anae Range, the Ko’olau Range, Nu’uanu Pali, and the Tantalus crater . . . weather permitting, of course.
The crater is the remains of O’ahu’s last gasp (maybe) of volcanic activity—the same gasp that produced Koko Crater, Koko Head, and Diamond Head—so it’s one of the few spots on the island that actually looks like a crater. It’s not as obvious as Diamond Head because it is covered in vegetation. Still, you can look down into a bowl from the summit. It does rain a lot here and the path can be slippery."
