About Diamond Head State Monument
Diamond Head State Monument, known natively as Leahi, is an iconic volcanic tuff cone that defines the skyline of Honolulu. It is world-famous for its historic trail that winds from the crater interior to military observation outposts built over a century ago. Standing at the summit rewards visitors with legendary panoramic vistas across Waikiki, the city, and the Pacific Ocean.
Don't miss
- Climb through historic 1908 coastal defense tunnels and conquer the steep summit stairways.
- Take in 360-degree views of Waikiki and the vast blue Pacific from the Fire Control Station observation deck.
- Explore the geological wonders of the massive volcanic crater floor where the hike begins.
- Spot the historic red-and-white Diamond Head Lighthouse set against the turquoise shoreline below.
Plan your visit
Early morning right as the gates open is the best time to visit to avoid the intense midday tropical heat. Early morning climbs also offer softer light and more comfortable conditions for photography.
Non-Hawaii residents must pay an admission fee and make an advance online reservation for entry and parking. Hawaii residents enter for free and do not need advance reservations.
From Waikiki, you can reach the monument easily via TheBus route 23 or by taking a short rideshare directly through the crater tunnel. Energetic visitors can also walk or rent a Biki bicycle from eastern Waikiki.
Tips for visiting
- Wear sturdy athletic shoes with good traction, as the trail has rocky, uneven surfaces and steep steps.
- Bring plenty of water and wear sun protection because there is minimal shade along the switchbacks.
- Reserve your timed-entry tickets well in advance, as popular morning slots frequently sell out.
- Ensure your phone is charged so you have a flashlight handy for the dimly lit tunnel sections.
- Pace yourself on the steep staircase near the summit and use the railings for balance.
Diamond Head State Monument FAQ
How difficult is the Diamond Head hike?
The hike is rated as moderate, covering roughly 1.6 miles round-trip with an elevation gain of 560 feet. While the path is partially paved, it includes uneven volcanic rock switchbacks and steep flights of stairs that can be taxing in the heat. Taking regular breaks at the trail switchbacks makes the trek manageable for most fitness levels.
Are there restrooms and water available on the trail?
Restrooms and water refill stations are located only at the trailhead inside the crater floor. There are no facilities or drinking water sources once you begin the ascent up the ridge. Make sure to use the facilities and fill your water bottle before starting your hike.
Is the hike stroller or wheelchair accessible?
The trail is not wheelchair or stroller accessible past the initial paved path near the visitor center. The route quickly turns into steep switchbacks, narrow historic tunnels, and long stairways. Families traveling with infants or small toddlers will need to use a wearable baby carrier.
What happens if it rains during the visit?
The park generally stays open during light rain, though the exposed rock surfaces and concrete steps can become quite slippery. Severe weather or high winds can occasionally cause temporary park closures for safety. If it begins to rain during your hike, use the handrails and descend cautiously.
