On the southern shore of Oahu, Diamond Head State Monument is one of Hawaii’s most iconic landmarks. This dormant volcanic cone, known as Lēʻahi in Hawaiian, offers breathtaking views and a journey through history, geology, and natural beauty. Hike Diamond Head because it’s a must-do for anyone visiting the island. Here’s a guide to help you prepare for and enjoy this remarkable adventure.

The History of Diamond Head
Before diving into the hike, it’s important to understand the significance of Diamond Head. Formed over 300,000 years ago, this volcanic crater is a remnant of a single explosive eruption. Its name comes from 19th-century sailors who mistakenly thought they had found diamonds in the rock. In reality, the “diamonds” were just calcite crystals.
During World War II, Diamond Head was used as a military lookout, and remnants of bunkers and military installations can still be seen along the trail.

Preparing for your Hike
What to Bring
Before you set out on your Diamond Head hike, make sure you’re well-prepared:
1. Water: Staying hydrated is crucial, especially in the Hawaiian sun. Bring at least 1-2 liters of water per person.
2. Snacks: A light snack, like trail mix or a granola bar, can give you that extra boost of energy.
3. Sunscreen: Protect your skin from the sun’s rays. Reapply regularly, especially when you sweat.
4. Hiking Shoes or Trail Runners: While the trail is well-maintained, sturdy footwear will make the hike more comfortable and reduce the risk of slips.
5. Camera: You’ll want to capture the stunning vistas, so don’t forget your camera or smartphone.
6. Light Jacket: If you plan to hike early in the morning or later in the evening, a light jacket can be helpful, as temperatures can drop.

Best Time to Hike Diamond Head
The Diamond Head hike is accessible year-round, but the best times to visit are early in the morning or late afternoon. These times offer cooler temperatures and less crowded trails. If you’re aiming to catch the sunrise or sunset, prepare to arrive early to secure a good spot. You must make a reservation through the website. Do this in advance, so you don’t get turned away at the gate. Whether you are driving or hiking to the trailhead, you still need to reserve your hiking time and show your reservation at the gate in the crater.
Trail Information
The trail is approximately 1.6 miles round trip, with an elevation gain of about 560 feet. While it’s a relatively short hike, the steep sections and staircases can be challenging, so be prepared for a workout. The trail is well-marked and generally suitable for families, though supervision is necessary for younger children.
The Hike: What to Expect
As you embark on the trail, you’ll start with a gentle incline that gradually leads to more strenuous sections. Here’s a breakdown of what you can expect:
1. The Initial Ascent
The first part of the trail features a wide path that is well-maintained. The lush greenery surrounding you provides a taste of Hawaii’s rich biodiversity. Keep an eye out for native plants and the occasional lizard darting across your path.

2. The Stairs
As you continue, you’ll encounter a series of steep staircases. This is where the hike becomes more demanding. The stairs, originally built for military purposes, can be a bit daunting, but take your time. The views start to open up as you ascend, rewarding your effort with glimpses of the coastline.

3. The Tunnel
Midway through the hike, you’ll navigate through a dark tunnel. This passage, another remnant of the military installations, adds a unique element to the adventure. Make sure to have your flashlight ready, especially if you’re hiking in low light.
4. The Final Push
The last section consists of steep switchbacks that lead you to the summit. Here, the anticipation builds as the panoramic views come into focus. The bright blue ocean and the green landscapes of the city of Honolulu below provide awesome photo opportunities!
