The Manana Ridge Trail is a long, scenic ridgeline hike in central Oahu, offering stunning views of the Koʻolau Mountains, Waiʻanae Range, and Waimano Valley. This challenging but rewarding hike is perfect for those looking for a remote adventure with fewer crowds. The trail also leads to Waimano Falls as a shorter alternative. Long and strenuous. The full hike is over 13 miles RT, but you can turn around early. Be comfortable with heights. The hike starts at Manana Neighborhood Park, in Pearl City. The first mile is gradual, passing through guava trees, strawberry guava, and eucalyptus groves. You'll encounter some muddy sections and small wooden bridges over stream areas. Mid-Hike: After about 3 miles, the trail becomes narrower and steeper. You’ll see stunning views of Waimano Valley and the Koʻolau Range. The trail alternates between shaded forest and exposed ridgeline sections. The last 1.5 miles are the most difficult, featuring narrow ridge sections with ropes to assist. The summit offers 360° views of the windward side, Pearl Harbor, and Waiʻanae Range. On clear days, you can see all the way to Chinaman’s Hat (Mokoliʻi Island)! Descent & Return: The return is just as challenging due to mud and steep drops. The full hike takes about 7 to 9 hours round trip, depending on pace.
