Hiking Diamond Head is a must-do activity for any visitor to Oahu. This guide provides everything you need to know to conquer this iconic volcanic crater, from planning your visit and navigating the trail to understanding its history and making the most of the breathtaking views from the summit.
Diamond Head State Monument: An Overview
Diamond Head, known as Lēʻahi in Hawaiian, is a volcanic tuff cone formed approximately 300,000 years ago during a brief, explosive eruption. Today, it’s a State Monument and a popular hiking destination attracting thousands of visitors annually. Located on the eastern edge of Waikiki, its distinctive silhouette is instantly recognizable and a defining feature of the Honolulu skyline.
The trail itself is a fascinating blend of natural beauty and historical significance. Built in 1908 as part of Oahu’s coastal defense system, the summit bunkers and observation points offer not only panoramic views but also a glimpse into the island’s military past. The hike is moderately challenging, accessible to most fitness levels, and rewarding with unparalleled vistas of Waikiki, the Pacific Ocean, and the surrounding Ko’olau mountain range.
Planning Your Diamond Head Hike: Reservations, Fees, and Timing
Reservations are now required to enter Diamond Head State Monument. You can book your entry time and parking (if needed) online through the Hawaii State Parks website up to 30 days in advance. Reservations are essential, especially during peak season (summer months and holidays), as walk-ins are generally not permitted. It is highly advised to book weeks in advance to ensure availability.
There are different types of reservations: one for entry only (if you’re walking or biking in) and one for vehicle entry and parking. Secure your spot in advance even if you plan to arrive by ride-sharing services to avoid hassle and unexpected turnarounds.
As of 2024, the entry fee is $5 per non-resident visitor; children 3 years and under are free. If you’re driving, the parking fee is $10 per vehicle. These fees help maintain the park and its facilities.
The monument is open from 6:00 AM to 4:00 PM, with the last entry at 4:00 PM. Everyone must exit promptly by 6:00 PM. The best time to hike Diamond Head is early in the morning to avoid the midday heat and crowds. Arriving around sunrise offers spectacular views, pleasant temperatures, and a more peaceful experience. The afternoon can be scorching, with little shade along the trail, making it more challenging and less enjoyable.

Ride-Sharing Services (Uber/Lyft): Uber and Lyft are readily available in Waikiki and can drop you off at the Diamond Head entrance. This is a good option if you don’t want to worry about parking, but remember that you still need an entry reservation.
Walking: If you’re staying in Waikiki, you can walk to Diamond Head. The walk takes approximately 45 minutes to an hour from central Waikiki. It’s a scenic walk along Kalakaua Avenue and Diamond Head Road. Be sure to wear comfortable shoes and bring water.

The Diamond Head Trail: A Step-by-Step Guide
The Diamond Head Trail is a 1.6-mile roundtrip hike that takes approximately 1.5 to 2 hours to complete, depending on your fitness level and how often you stop to take pictures (which you’ll want to do a lot!). The trail is mostly paved but includes some steep sections, stairs, and a dark tunnel.
Starting Point: The trail begins inside the crater, after you pass through the entrance tunnel. You’ll find restrooms, a water fountain, and a snack bar here. Make sure to fill up your water bottle before starting the ascent.
The Initial Climb: The first part of the trail is a paved, gently sloping pathway leading towards the crater wall. This section offers nice views of the crater floor and the surrounding area but provides minimal shade.
The Switchbacks: The trail then begins to ascend more steeply via a series of switchbacks carved into the crater wall. These switchbacks offer stunning views of Waikiki and the Pacific Ocean. Take your time and enjoy the scenery as you climb.
The Stairs: After the switchbacks, the trail enters a series of stairs carved into the rock. These stairs can be challenging, especially in the heat, so pace yourself. There are several rest stops along the way.
The Tunnel and Spiral Staircase: One of the most distinctive features of the Diamond Head Trail is the dark, narrow tunnel that you must pass through. After the tunnel, you’ll encounter a 99-step spiral staircase leading to the summit observation point. This staircase can be crowded, but the views from the top are well worth the effort.
The Summit Bunkers: At the summit, you’ll find several old military bunkers and observation points. Explore these structures and learn about the history of Diamond Head and its role in Oahu’s defense. Take plenty of photos of the panoramic views of Waikiki, the coastline, and the Ko’olau mountains.
The Descent: The descent is generally easier than the ascent, but be careful on the steep sections and stairs. Remember to take your time and enjoy the views as you descend. Watch your steps while descending the staircase.

Diamond Head’s History and Cultural Significance
Diamond Head is more than just a scenic landmark; it holds significant historical and cultural importance. The Hawaiian name, Lēʻahi, refers to the brow of the tuna, reflecting its resemblance to a tuna’s dorsal fin when viewed from a certain angle. It served as a navigational landmark for ancient Hawaiians.
In the late 18th century, Western sailors mistakenly believed they had discovered diamonds on the crater slopes, hence the name “Diamond Head.” However, the “diamonds” were actually calcite crystals. In the early 20th century, the U.S. military recognized the strategic importance of Diamond Head and built a network of bunkers and observation points to defend Oahu. These structures, which are still visible today, played a crucial role in the island’s defense during World War II.
Today, Diamond Head is a State Monument, protecting its natural and cultural resources. Preservation efforts are ongoing to maintain the trail, bunkers, and surrounding area for future generations.
