Top things to do
Diamond Head Summit Trail
A 1.6-mile round-trip climb of about 560 feet from the crater floor to the rim, with switchbacks, two long stair sections, and a lighted tunnel near the top, ending at a historic fire-control station and lookout with sweeping views over Waikiki and the south shore.
Summit views over Waikiki and the coast
From the 560-foot rim the trail opens to panoramic views of Waikiki, Honolulu, the Pacific, and the south Oahu coastline, the payoff that makes this one of the island's most popular hikes.
The volcanic crater and military history
Diamond Head, or Leahi, is a roughly 300,000-year-old tuff cone, and the trail passes World War I-era bunkers, tunnels, and the fire-control station that once helped direct coastal artillery.
Anchor the day around Diamond Head Summit Trail
Put the access rule first: shuttle, parking, timed-entry, or reservation windows should decide the order of the day. For one day in Diamond Head State Monument, make Diamond Head Summit Trail the non-negotiable, add Summit views over Waikiki and the coast only if the first stop runs clean, and keep The volcanic crater and military history as the flexible finish.

Where to stay
There is no camping at Diamond Head; it is a day-use monument. Almost all visitors stay in nearby Waikiki and Honolulu, minutes away with the island's densest concentration of hotels and rentals, and reach the crater by car, rideshare, bus, or tour. For state-park camping on Oahu, look to coastal parks elsewhere on the island, which have their own permit systems. Treat Diamond Head as a half-day hike from a Waikiki base.

Car strategy
Most visitors drive or take a rideshare through the tunnel into the crater, where the parking lot and trailhead sit on the crater floor, while city buses and tours also serve the monument.
Local movement
Out-of-state visitors driving in must hold an advance reservation for entry and parking, and parking inside the crater is limited, so an early timed slot is the reliable approach.
Pair this with lodging: sleep where the park transfer is simple, especially if your route needs an early start.
