The Trail: What to Expect
Trailhead to Switchbacks
0 to 0.4 milesEasyPaved and well-maintained path through the crater floor. Gradual incline with great views back across the crater interior. This section is easy for all ages and fitness levels.
Switchbacks
0.4 to 0.6 milesModerateThe trail becomes steeper here with a series of switchbacks carved into the crater wall. Paved but more strenuous. Take it slow and enjoy the improving views of Waikiki below.
Tunnels and Stairs
0.6 to 0.75 milesModerateThe most unique part of the hike: a narrow lighted tunnel (bring a flashlight or use your phone), followed by a 99-step spiral staircase inside the crater wall, originally built for a WWII observation post. Claustrophobic visitors should know this section is tight.
Summit Lookout
0.8 miles (top)EasyThe reward: a 360-degree panorama of Waikiki, Honolulu, the Pacific Ocean, and the Ko'olau Mountains. Multiple platforms at the summit allow you to spread out. The view at sunrise is extraordinary.
What to Bring
Water
At least 16–32 oz per person. There is no water available on the trail. Dehydration in the heat is a common issue.
Athletic shoes
The trail is paved but steep. Flip-flops and sandals are not suitable. Sneakers or trail shoes work well.
Flashlight or phone torch
The tunnel section is dimly lit. Your phone's flashlight is sufficient.
Sunscreen
The summit is fully exposed. Apply before you start. The hike takes 45–90 minutes and the sun reflects off the crater walls.

Online reservations are required. Have your confirmation ready on your phone at the entry gate.
Snacks (optional)
Not required, but a granola bar or fruit at the summit makes the experience more enjoyable.
Best Time to Hike
Sunrise (Best)
Trail opens at 6 AM. Arrive at the trailhead by 5:45 AM to reach the summit at sunrise. The light is spectacular, the temperature is cool, and you'll share the summit with far fewer people.
Early Morning (Good)
6–8 AM is still excellent. After 9 AM the trail gets crowded and the heat builds quickly. By midday the temperature at the summit can exceed 90°F with no shade.
Frequently Asked Questions
Do I need to book Diamond Head tickets in advance?
Yes. Online reservations are strongly recommended and often required during peak season. Tickets are $5 per person plus $10 for parking (if driving). Book at gostateparks.hawaii.gov. Walk-ins are sometimes available but limited. Reserve your spot as soon as your dates are finalized.
How hard is the Diamond Head hike?
Diamond Head is a moderate hike suitable for most fitness levels. The 1.6-mile round trip involves 560 feet of elevation gain, a 99-step spiral staircase, and a narrow tunnel. It takes most people 45–90 minutes round trip. Wear athletic shoes and bring water. It is not appropriate for strollers.
What time should I hike Diamond Head?
Sunrise is the best time to hike Diamond Head. The trail opens at 6 AM, the temperature is cool, and you'll reach the summit as the sun rises over the Pacific. By 9–10 AM, the trail becomes crowded and the heat makes the climb significantly less comfortable. If you can't do sunrise, go as early as possible.
How do I get to Diamond Head?
Diamond Head State Monument is about 2 miles east of Waikiki. Parking inside the crater is limited and fills by 7–8 AM on weekends ($10/car, reservation required). TheBus Route 23 or 24 stops nearby. Rideshare from Waikiki runs about $10–$15. Many hotels offer shuttle service.
Can I hike Diamond Head with kids?
Yes, with caveats. The hike is manageable for children 6 and older who are comfortable with stairs and a short tunnel. The 99-step spiral staircase and narrow tunnel can be intimidating for younger children. There is no stroller access. Bring snacks, water, and plan for a slower pace.
Is the Diamond Head hike worth it?
Absolutely. The summit view over Waikiki, Diamond Head beach, and the Pacific is one of the most iconic in Hawaii. The WWII history inside the crater and the tunnel/staircase add an unexpected element of adventure. At $5 per person, it is one of the best-value experiences on the island.
