Diamond Head Crater is one of the most famous landmarks in the state of Hawaii. Diamond Head (Le'ahi in the Hawaiian Language) is a tuff cone crater that was formed by volcanic eruptions on the island of Oahu some 300,000 years ago. Today, most people consider Diamond Head to be extinct. This means that it will never erupt again. Looking south from the tranquil shores of Waikiki, Diamond Head offers one of the most picturesque tropical backdrops on the planet.

The Diamond Head State Monument is now a part of the Hawaii State Park system. Inside the crater there is a trail that leads up to the summit. The hike is 1 mile and the elevation at the summit of the trail is approximately 600 feet above sea level. If you plan to hike to the summit, wear comfortable shoes and bring plenty of water. The inside of the crater can get really hot. The Diamond Head State Monument is open from 6am to 6pm daily and there is an entrance fee.
