Diamond Head is one of the most famous symbols of Hawaii. Overall an easy hike, people of all ages will be able to make it to the top. The spectacular panoramic view found at its height of 750 feet will be an unforgettable part of your trip to Hawaii!
Please be sure to read the Cancellation Terms on the About Booking Request page.


Tachibana Enterprises provides round trip transportation as a part of its tour, and provides a ride from your hotel directly to the entrance of Diamond Head State Monument. The tour package includes your entrance fee, which is paid for at the gate.

The hike begins with a short walk from the entrance area. There is only one restroom available right past the entrance area (the white building shown on the left). There will be various lookout points for taking pictures so enjoy the hike at a relaxed pace as the hike will only take about 40 to 45 minutes.

At first, it will be a concrete walkway. The trail is over a flat surface and then will begin to get rocky, marking the start of the ‘real’ hiking experience. We do not recommend sandals or shoes that have heels on them.

From the entrance to the top of the hill is a 0.7 mile hike and you will climb to height of approximately 560 feet. One short part of the trail is a steep climb and so take it slow and easy. We recommend wearing a hat and putting on sunblock lotion.

Right after the first lookout point, you will come across the first set of stairs. There are a total of 76 steps, and they can be taken slowly. At the top of the stairs, there will be a tunnel that will lead to a second set of stairs. You are now close to the top of Diamond Head, just a short hike more!

After the second set of stairs, there will be yet another tunnel which will lead to a spiral staircase up into a concrete room at the top. The room is an old military observation post for Battery Harlow (Fort Ruger), and Diamond Head hike certificates are sold there. The cost of the certificate is included in your tour package with Tachibana Enterprises and so there is no need to purchase from your side.
You will go out of the room through a small exit and you will immediately see the beautiful blue ocean. Diamond Head Beach can be seen down ahead of you, but please do not stop to enjoy the view just yet. Keep moving forward!
After a short hike down a narrow path, you will come to the final set of stairs, which consists of 20 short steps. Once you reach the top, you will see a stunning view of the ocean, Waikiki, and other beautiful parts of the island. Go on this hike and see it all with your own eyes! After you’ve enjoyed the beautiful views of the island, you will go back the way you came.

The tour package will include one bottle of water per person; however, if you would like to purchase something more to drink, you will be able to do so at the snack bus shop (cash only).

Your transportation will be waiting for you at the same place you were dropped off. If you finish the hike earlier than the estimated time, please wait in the pick up location. The driver will pass out your Diamond Hike certificate and then drive you back to your hotel.

How The Crater Was Formed
  The pronounced seaward summit, deeply eroded ridges, and ovoid-shaped crater as evidence of Leahi's very dynamic geological history. The creation of Oahu began around 2.5 to 4 million years ago with volcanic eruptions from 2 shield volcanoes. A period of extensive erosion followed, leaving the Koolau and Waianae Mountain Ranges as the remnants of these volcanoes.
  After about 1.3 million years of volcanic inactivity, the southeastern end of the Koolau Range erupted. These eruptions occurred under the ocean, where the magma was broken down into ash and fine particles by the water and steam. Blown into the air, these particles were cemented together into a rock called tuff which created tuff cones, such as Leahi.
  Leahi is believed to have been formed about 300,000 years ago during a single, brief eruption. The broad crater covers 350 acres with its width being greater than its height. The southwestern rim is highest because winds were blowing ash in this direction during the eruption. Since the eruption, the slopes of the crater have been eroded and weathered by rain, wind, and the pounding of the sea. A coral reef now protects the seaward slopes of the crater.
  Today, Leahi (Diamond Head) is the most recognized landmark in Hawaii. It was designated a National Natural Landmark in 1968 as an excellent example of a tuff cone.

  The semi-arid climate, the steep rocky slopes, and the shallow soil of Diamond Head support mostly low shrubs and herbs. Botanists believe that the crater was once covered by a dryland forest, but only a few native Hawaiian species remain. Rainwater collects on the crater floor in the winter, creating a small lake that was frequented by native ducks, coots, and gallinules until the early 1900s.
  Most of the plants and animals you see in the crater today were introduced to Hawaii after the 1800s. Dominant plants are the kiawe, a relative of the mesquite, and koa haole. Both of these plants were brought in as cattle feed and have adapted well to the hot, dry conditions. You may see some of the common introduced birds, such as cardinals, doves, and sparrows.
The Early History
  It is said that Hiiaka, sister of the fire goddess Pele, gave Leahi its name because the summit resembles the forehead (lae) of the ahi fish. Another translation is "fire headland" and refers to the navigational fires that were lit at the summit to assist canoes traveling along the shoreline. The heiau (temple) built on the summit was dedicated to the god of wind as protection against strong updrafts that could put out these navigational fires. Today, the Diamond Head Light, built in 1917, provides a visual aid for navigation.
  In the late 1700s, Western explorers and traders visited Leahi and mistook the calcite crystals in the rocks on the slope of the crater for diamonds. Thus, the name Diamond Head came into common useage.

Military History
With its panoramic view from Koko Head to Waianae, the summit of Diamond Head was an ideal site for the coastal defense of Oahu. In 1904, Diamond Head was purchased by the Federal government and designated for military use. Fortification began in 1908 with the construction of gun emplacements and an entry tunnel through the north wall of the crater from Fort Ruger known as the Kapahulu Tunnel.
  Batteries were built to house the coastal artillery. A total of 5 batteries were built at Diamond Head Crater: Harlow (1910) on the northern exterior, Dodge and Hulings (1913) which tunnel through the eastern crater wall, Birkhimer (1916) which is largely below ground inside the crater, and Battery 407 (1943) which tunnels through the southern wall.
  Fire Control Station Diamond Head was built at the summit between 1908-1910 and housed instruments and plottings rooms to direct artillery fire from several batteries.
  From this observation station, observers could triangulate targets and aim artillery and mortar fire from Batteries Randolph and Dudley at fort DeRussy in Waikiki and Battery Harlow at Fort Ruger on the outer slopes of the crater. Consisting of 4 levels, the exterior of the Fire Control Station was camouflaged with rubble embedded in concrete. Slits on each level provided seaward viewing for potential sea and air attacks. The 4 levels and the summit were accessed by a spiral staircase and ladders.
  Additional coastal defense was provided by long range guns installed on the outer slopes and rim of the crater around 1915. Diamond Head was prepared to defend Oahu from attack but no artillery was ever fired during a war.
  The military features of Diamond Head are part of the Fort Ruger Historic District.

    Points Of Interest Along The Trail
  1. The trailhead at the parking lot is located on the crater floor at an elevation of about 200 feet (61 m).
  2. The concrete portion of the trail was recently installed to reduce trail erosion. The former pistol ranges are marked by earthen berms visible along the lower section of the trail.
  3. The dirt trail conforms to the 1908 trail alignment and consists of numerous switchbacks up the steep interior slope.
  4. Concrete Landing/Lookout. This foundation held a winch and cable to lift materials from the crater floor to this point.
  5. Steep stairway of 74 concrete steps leading into the first tunnel.
  6. Passage through a lighted 225-foot long, narrow tunnel.
  7. Second stairway consisting of 99 steep steps. The cross-beams above the stairway supported camoflaging.
  8. At the top of the stairs is the entry to the lowest level of Fire Control Station Diamond Head which housed the observation equipment for Fort DeRussy at Waikiki.
  9. The lighted spiral staircase accesses the 4 levels of the Fire Control Station. Go up the 52 stairs to the third level where the mounts for the observation equipment are still present.
  10. Exit to the exterior of the crater through slits once covered with metal shutters. Note the rock and concrete that camouflage the structure on the seaward side.
  11. The 54 metal stairs replaced the ladder to the summit in the 1970s for hiker safety.
  12. The summit of the crater and the uppermost level of the Fire Control Station are at an elevation of 761 feet (232 m). Bunkers along the crater rim were built in 1915.
