Diamond Head Hike: What To Expect

The Diamond Head trail is family friendly and should be pretty easy for anyone with decent fitness, but you’ll want to bring water and sunscreen.

The only thing that makes it a bit more difficult is the mid-day heat and some uphill sections that can be strenuous. Go early in the morning or late in the afternoon for cool weather and less crowds.

A large part of the trail is paved with railings, but it does get a bit crowded because it’s one of Oahu’s most popular attractions and it’s so close to Honolulu.

After a small tunnel and about 100 steps, you’ll reach a lookout point with a World War II bunker. Climb another 50 steps from there, and you’ll reach the summit.

The great thing about the Diamond Head overlook is that you get fantastic summit views of the Diamond Head crater (leftovers of an old volcanic eruption), along with some lookout pillboxes from World War II, and Honolulu city in the background.

All in all, the Diamond Head trail is a worthy addition to your Honolulu hike list. As always, please remember to keep the trail clean, be considerate of other hikers, and leave no trace. Thanks and happy travels!

How To Get There

Diamond Head crater is located just south of Waikiki and Honolulu, on the island of Oahu, Hawaii.

It’s a 10 minute drive from Waikiki by car, or 20-30 minutes if you take TheBus.

Keep in mind there’s no bus stop inside of Diamond Head crater (the nearest stops are by the outside rim), so there’s an extra 10 minutes of walking involved if you go by bus.

However, the Waikiki trolley has a stop just inside the crater, and you can buy a trolley pass here.

Best Time To Visit

Generally the best time to climb Diamond Head is in the morning, that way you avoid most of the heat and crowds.

Photography is great at the Diamond Head lookout all day long, so you should get spectacular views and pictures at any time of the day.

Diamond Head vs Koko Head

So in a comparison of the Diamond Head hike vs Koko Head, how do these two popular volcano hikes in Oahu stack up? That’s a good question, and I’ll try to answer.

Both hikes are roughly the same distance roundtrip (1.8 vs 1.6 miles), and they take roughly the same amount of time to complete, but Koko Head has about 50% more elevation gain than Diamond Head crater. That means Koko is steeper and harder.

The path on the Diamond Head trail is in much better condition than the Koko stairs, so it’s definitely more suitable for kids and older people. If you want a good workout and calorie burn, however, Koko Head wins there. Koko is also better for seeing the sunrise or sunset.

The views at the summits are different, but great on both hikes. Diamond Head and Koko Head are both extinct volcano craters, and you can see old World War II military bunkers (‘pillboxes’) at the top of either summit.

Diamond Head is closer to the city and it has amazing views of Waikiki and Honolulu, while Koko Head has amazing views of Hawaii Kai and Hanauma Bay. Overall, they’re both great hikes if you have time!
