Oahu Diamond Head Hike – Is it Worth the Effort?

Diamond Head (Lēʻahi) is the volcanic crater at the eastern end of Waikiki that appears in roughly every aerial photo of Honolulu. The hike to the summit is 1.6 miles round trip, moderately steep, and entirely worth it for the 360-degree views of Waikiki, the Pacific, and the Ko’olau Mountains. You’ll need a reservation. Go early. Bring water. Don’t wear heels. This is genuinely advice people need.

Diamond Head Adventures told by an Oahu tour guide

Long ago I used to be a nature tour guide. The Diamond Head hike was one of our most popular tours, so I made regular treks up the mountain at 7 am and 9 am. After I quit (there was an incident involving a large van, a really small parking garage and a manic boss), I felt no need to return to Diamond Head. Until that is, family and friends visited and it was time to play tour guide once again.

Over the decades since my time as a tour guide, some things were still the same. The sweltering heat, the many, many stairs, the regulars trying to run through the crowds, the narrow tunnel (hello claustrophobia), the tourists wearing heels, and of course, the stunning views. Major changes include an improved trail and a new reservation system which has reduced overcrowding. A huge improvement.

So is the hike worth the trouble? I say yes. There’s something undeniably fascinating about hiking inside and to the summit of a geological phenomenon and bit of world history. It’s a unique opportunity to summit Hawaii’s most iconic symbol and the views can’t be beat. As for the kids, toddler Mila was a little bored and asked to be carried while 5-year-old Micah thought everything was amazing. He loved the bunkers, the stairs, the tunnel and eagerly ran ahead outpacing all of us.

Getting there

The unique profile of Diamond Head (Lē‘ahi) sits prominently near the eastern edge of Waikiki’s coastline waiting to be explored and there are several ways to get there. You can drive (about 15 minutes from Waikiki) and park inside the crater ($10 fee) but space is limited. Alternatively, you can take –

• A rideshare for approximately $30 round trip.
• A trolley $25 per person for the day but who doesn’t love a trolley?
• The city bus ($6 round trip per person in cash). Google your location to Leahi Millennium Peace Garden and walk 15 min to the trailhead).
• A bike. Rent a biki bike from one of the many bike sharing stations. Warning, it will be an uphill journey to the trailhead.
• Walk. It can be a long, hot, shadeless walk, but you see more on foot. You can shorten your walk by parking near the Diamond Head Lookout. Check out the lighthouse and watch surfers catch an endless set of waves before making your way around the crater. This section is part of the Honolulu Marathon.

The park is open from 6 am to 6 pm daily with the last reservation at 4pm. Although Hawaii residents are free (go early as kama’aina parking is limited), visitors are required to pay $5 per person (3 years old and under are free) and $10 for parking. Reservations to park and hike must be made beforehand up to 30 days before your intended visit.

What to bring

This is a straightforward hike — clearly marked, hard-packed trail, no technical gear needed.

Shoes. A light hiking shoe or anything with laces. The trail is uneven in places but not technical.

Sun protection. The trail is fully exposed from bottom to top. Sunscreen, a hat, and a UV shirt if you have one. Go early or late to avoid the worst heat.

Water. More than you think you need. It’s hot and there’s no shade. This is the number one reason people struggle on this trail.

For kids. Snacks help. Geocaching works well on the way up if you have a reluctant hiker. The bunkers and the tunnel tend to be the highlights for kids who find the walking part less thrilling.

Camera. The summit views are worth it.

Dogs. Not allowed on the Diamond Head trail.
