Two Hikes, One Island: Morning at Diamond Head and Manoa Falls
Two short but contrasting hikes that show the coastal sweep and rainforest heart of Oahu
By the time the van slips away from the thread of Waikiki hotels and dips under the shadow of the volcanic cone, Honolulu has just begun to wake. You stand at the trailhead of Diamond Head — Leahi to Hawaiians — with the Pacific laid out like glass, an early sun polishing the surf of Waikiki into a long ribbon of light. The climb ahead is short and steep: concrete steps, a switchback, a tunneled stairway that has carried soldiers and sightseers for a century. But the crater keeps its own rules. It nudges, tests, and rewards. At the rim the view opens suddenly and simply. You feel the island at once: the city, the reef-edged sea, the long sweep of the south shore, and the ragged shoulder of Koko Crater far to the southeast.
Trail Wisdom
Start early
Begin at first light to avoid crowds and midday heat at Diamond Head and to enjoy softer light in Manoa Valley.
Footwear matters
Wear shoes with good traction — Diamond Head has concrete steps; Manoa can be muddy and slippery after rains.
Respect posted signs
Swimming at Manoa Falls is sometimes prohibited for health reasons; follow closures and stay on trails to protect native plants.
Hydrate and snack
Pack at least 1–2 liters of water and energy snacks, especially for the exposed climb at Diamond Head.

Conservation Note
Stay on marked trails, pack out waste, and avoid disturbing native plants; check advisories before swimming at waterfall pools due to water-borne bacteria.
Diamond Head (Leahi) was used as a coastal defense lookout and has military bunkers from the early 20th century; Manoa Valley historically supported Hawaiian taro cultivation and remains culturally significant.
