Diamond Head Crater is a stunning volcanic landmark that has captured the attention of visitors from the beginning of time.
Ancient Hawaiians first named the extinct volcano
Le’Ahi for its strong
Ahi-Tuna-fish brow like appearance.
Later in the 1800’s, British sailors were fooled by the glittering
stones that are embedded at the top of the
diamonds were discovered, but Le’Ahi received its new name “Diamond
The Diamond Head trail itself was originally built in 1908 by
the US Army, and used for many decades as part of the Fort Rugur
military base. Artillery cannons, cement bunkers and an
observation deck were built on the summit of the Diamond Head Crater.
Today Diamond Head has been turned into a state national park. You will need to enter the Diamond Head park from the eastern side, through a short tunnel that will bring you into the center of the crater, where you will start your 560 foot ascent.
Hiking Diamond Head is suitable for most, including children,
golden agers, and the average person who does not exercise daily or participate
in many hikes for recreation. However, please know your own health condition and wear the appropriate gear for this moderate hike.
You will find the beginning of the Diamond Head trail on the west side of the crater, where you start your ascent slowly up a sidewalk path that turns into a switchback rock pathway.
There are lots of loose gravel and potholes on the trail, so take caution with your footing to prevent
slipping and falling.
I have seen a few hikers on this Oahu hiking trail wearing flip-flops that are meant more for the beach. Although they
might get away with it, I would recommend wearing something with
stronger support and grip, such as hiking or trail running shoes.
The switchback trails will take you quickly up to the first
lookout, where I recommend taking a moment to catch your breath and
enjoy some beautiful ocean views.
The next section of this Diamond Head hike involves narrow long stairs –lots of stairs! This will lead you to a lit 225 ft tunnel that you will need to pass through.
As you exit the 75-yard tunnel, you will see a double headed painted arrow on the wall pointing 2 ways to the top. Turn left and it's a long path with a series of stairs leading to the top platform. Turn right and it's a straight shot up.
99 steps will lead you straight up to an old military bunker room with a spiral staircase leading up to the top. That's right, more stairs that will finally lead you to the top of the pillbox lookout.
Not too long ago, you had an opportunity to purchase a Certificate of Achievement for doing the Diamond Head hike for a small donation of $2.00! You will have to settle for a souvenir once you reach the bottom.
The spiral staircase adds another layer, mystery, and sense of adventure to this amazing Oahu hike! And while this signifies the end of the climb, there are more stairs and platforms up top to explore.
The backside stairs gives you an amazing view of the Diamond Head Crater, and the coastline leading down to the Koko Crater. Most climbers take this route back down to the bottom. You can climb up 1100 steps next at the Koko Crater if you're up for it!
The gorgeous 360-degree views from the viewing decks are
breathtaking! Not because you’re out of breath from climbing
all the stairs, but because of the panoramic views of Waikiki to
Waianae, the vast Pacific Ocean, the Ko’olau Mountains, and eastern
views reaching out to the Koko Head Crater.
Diamond Head Crater also holds the record for the longest recorded land views in the world. On a clear day, I think I would have to agree!
