Suitable for hikers in average shape who can handle sustained stairs and short uphill sections; expect repeated elevation changes.
Combine two of Oahu’s most distinct walks in one day: the sun-exposed crater climb of Diamond Head and the rainforest approach to Manoa Falls. This guided package from Waikiki gives hikers a compact, practical introduction to the island’s geology, culture, and terrain.
The day begins with Waikiki sliding away in the minibus windows and the Pacific pressing a bright line on the horizon. By the time hikers step out at the rim of Diamond Head (Leahi), the crater’s steep inner walls already press a wind that smells like sun-warmed grass and salt. The path climbs quickly—paved switchbacks, tunneled staircases and a final metal ladder—and opens into a 360-degree view that takes in Waikiki’s skyline, the reefed surf, and the jagged green of Koʻolau Ridge.

Arrive early—start Diamond Head at first light to avoid midday sun and long summit queues; Manoa is cooler earlier in the day but becomes muddy after rain.
Wear closed-toe shoes with good traction for Manoa’s roots and mud; Diamond Head’s paved sections are easier on trail runners.
Bring at least 1 liter of water per person for the day; refill in Waikiki before departure since sources are limited on trails.
Stay on marked paths, avoid edging around muddy sections to prevent widening the trail and damaging native plants.
Diamond Head served as a strategic military lookout in the early 20th century and contains tunnels and bunkers; Manoa Valley has long been cultivated and appears in local folklore and plantation history.
Stick to established trails to protect fragile native flora; invasive species and trail widening are current concerns—pack out trash and follow Leave No Trace principles.
Keeps you hydrated through the exposed climb of Diamond Head and humid Manoa Valley.
