An easy beginning
The route starts near the parking area on a paved concrete walkway. This is the gentlest part of the climb.

Plan the iconic crater hike above Waikiki, with current reservation details, trail expectations, parking guidance, and the exact location.
Waikiki's defining landmark
Diamond Head, known in Hawaiian as Lēʻahi, rises at the eastern edge of Waikiki. Its summit trail is compact, steep, exposed, and memorable, finishing with wide views over the Honolulu coast.
The route is not a wilderness trek. It is a heavily visited state monument with timed entry, paved sections, switchbacks, stairs, a lighted tunnel, historic military structures, and a relatively small summit area. Good planning matters more than distance.
For most Waikiki visitors, this works best as a focused morning or late-afternoon outing. Reserve before leaving your hotel, bring water, and give yourself enough time to enjoy the view without racing the gate schedule.
Book before you go
Advance reservations are required for non-Hawaiʻi residents. Entry and parking are booked separately through the official State Parks reservation system.
The summit route
The route starts near the parking area on a paved concrete walkway. This is the gentlest part of the climb.
The surface becomes uneven and the trail climbs across the dry inner wall of the crater with little shade.
Expect steep stairways and a lighted 225-foot tunnel before entering the historic fire control station area.
The reward is an expansive view across Waikiki, Honolulu, the south shore, and the Pacific.

Know before you climb
The trail is only 0.8 mile each way, but the heat, exposed slope, stairs, and steady elevation gain make it feel more demanding than the distance suggests.
Practical visitor guide
Earlier reservations usually mean cooler conditions, but morning slots are also popular. A later visit may feel hotter and leaves less room for delays before the gate closes.
The park is normally open daily from 6:00 a.m. to 6:00 p.m. and closed on Christmas Day and New Year's Day. Always check the official park page for closures or notices before leaving Waikiki.
Exact location
Entrance from Diamond Head Road, between Makapuʻu Avenue and 18th Avenue, Honolulu, HI 96815.
The crater has limited parking. Non-resident parking must be reserved online with the correct arrival period.
A drop-off avoids the parking reservation, but every non-resident visitor still needs a valid entry reservation.
Transit can bring you near the monument, but routes and stops change. Check the current trip planner before departure.

More than a viewpoint
Diamond Head's broad tuff crater formed roughly 300,000 years ago during a single explosive eruption. Ash and fine particles settled and cemented together, creating the recognizable rim above Waikiki.
The summit trail was built in 1908 as part of Oʻahu's coastal defense system. The route passes through a tunnel and into the fire control station completed in 1911, which once helped direct artillery fire from nearby batteries.
Quick answers
Yes, non-Hawaiʻi residents need an advance entry reservation. Parking requires a separate reservation. Hawaiʻi residents with valid state identification are exempt from the entry fee and reservation requirement, although resident parking is not guaranteed.
The official trail information lists about two hours, while many visitors complete the hike itself in 60 to 90 minutes. Allow 1.5 to 2 hours for entry, breaks, the summit view, and returning to the crater floor.
It is officially rated moderate. The distance is short, but the heat, 560 feet of climbing, uneven surface, tunnel, and steep stairs make it physically demanding for some visitors.
Many active families complete the trail, but adults should consider each child's comfort with heat, stairs, crowds, and sustained uphill walking. Strollers cannot be used on the summit route.
Yes. Rideshare, taxi, guided transportation, or public transit combined with walking can work. Non-residents still need an entry reservation even when they do not park inside the crater.
No. Facilities on the crater floor are accessible, but the summit trail is steep, uneven, and includes stairs.
