Diamond Head Professional Review and Guide
"The name is Le’ahi to Hawaiians. This is the most famous landmark in all Hawai’i, the classic hike everybody must do when they come to O’ahu. Wilderness it is not. From opening to closing a steady stream of hikers of all ages, sizes, and states of physical fitness (or lack thereof) puffs up and down the steps. For many locals, it’s a popular conditioning run (yes, run!). The view from the top is superb in all directions, as you would expect.
The hike is well described in the brochure you receive at the kiosk as you enter. The maps are detailed, easy to follow, and the accompanying information is interesting and entertaining. In a nutshell, however, you begin along a flat concrete walkway that gradually begins to gain elevation. The concrete ends and a trail with handrails begins zigzagging more steeply uphill."
