Muddy section with ropes

The Ala Wai Canal – Mount Olympus Summit loop from University of Hawaiʻi at Mānoa offers a deep dive into Oahu's rugged interior, combining urban access with challenging ridge hiking. You'll traverse through dense, humid forests, navigating steep ascents over tangled roots and slick red clay, especially on trails like Kolowalu. As you gain elevation, the views open up dramatically, culminating in spectacular 360-degree panoramas from the summit of Mount Olympus, revealing Mānoa Valley, Diamond Head, and the vast Pacific.

This difficult 13.1-mile (21.0 km) route, with its 2517 feet (767 metres) of elevation gain, typically takes around 6 hours and 34 minutes to complete. Be ready for a serious workout and potentially very muddy conditions, particularly after rainfall, which can make sections extremely slippery and necessitate the use of ropes. Accessing the trailhead from the University of Hawaiʻi at Mānoa means you're close to urban amenities, but the trail quickly transports you into wilder terrain.

Mount Olympus, or ʻAwaʻawaloa, holds historical significance, reportedly named by Punahou students in the 1800s. It's a prime example of Oahu's ridge hiking, offering a chance to see native Hawaiian plants like ʻōhiʻa lehua and uluhe ferns. The trail's proximity to Honolulu makes it a popular, yet demanding, choice for experienced hikers seeking expansive views and a true taste of the island's natural beauty.

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.
