This ambitious route combines a leisurely urban walk with a challenging mountain ascent, offering a unique perspective of Oahu. You'll start with the paved path along the Ala Wai Canal, enjoying waterside views and the distant Hawaiian mountains, before transitioning to the strenuous ridge hike up Mount Olympus. Expect steep scrambles, potentially muddy conditions, and even rope-assisted sections on your way to the summit, where you'll be rewarded with breathtaking 360-degree panoramic views of Honolulu, Manoa Valley, and Diamond Head.
While the Ala Wai Canal is easily accessible from Waikīkī, the Mount Olympus trailhead requires a short drive, making this more of a combined experience than a continuous walking loop. Plan for transportation to the Wa'ahila Ridge State Recreation Area, about 15 minutes from Waikīkī. An early morning start is best for clear summit views, especially given the route's difficult rating, 13.6 miles (21.8 km) distance, 2463 feet (751 metres) of elevation gain, and estimated 6 hours and 46 minutes duration.
Mount Olympus offers a quintessential Ko'olau ridge hiking experience, known for its dramatic terrain and expansive vistas. The contrast between the urban canal path and the rugged mountain ridge highlights the diverse natural beauty surrounding Waikīkī, making it a rewarding challenge for experienced hikers seeking varied scenery and a significant workout.
