The extinct crater of Diamond Head is now a state monument, with picnic tables and a hiking trail up to the 760ft-high summit. The trail was built in 1908 to service military observation stations located along the crater rim. Although a fairly steep trail, it’s partly paved and only 0.8 miles to the top, taking about an hour round-trip. Plenty of people of all ages make the hike.

The trail, which passes through several tunnels and up head-spinning staircases, is mostly open and hot, so wear a hat and sunscreen and bring plenty of water. The windy summit affords fantastic 360-degree views of the southeast coast to Koko Head and the Leeward Coast to the Waiʻanae Range.

The state park has restrooms, drinking fountains, vending machines and a picnic area. From Waikiki, catch bus 23 or 24; from the closest bus stop, it’s about a 20-minute walk to the trailhead. By car, take Monsarrat Ave to Diamond Head Rd and turn right immediately after passing Kapiʻolani Community College (KCC).
