Maunawili Trail (Koolaupoko Trail)
Kailua / Waimanalo
The Maunawili Trail is one of Oʻahu's classic backcountry hikes, traversing the lush windward side of the Koʻolau Mountains between the Nuʻuanu Pali area and Waimānalo/Maunawili. Rather than leading to a single viewpoint or waterfall, it is a long forest traverse through bamboo groves, stream crossings, and tropical rainforest.
The trail is especially popular with experienced hikers, trail runners, and mountain bikers due to its length and varied terrain. Historically, it has been about 10 miles one-way, making it one of the island's premier point-to-point hikes.
Why Roamwise recommends this
The Maunawili Trail is one of Oʻahu's premier rainforest traverses, offering a full-day journey beneath the towering Koʻolau Mountains through bamboo forests, muddy stream valleys, and lush tropical vegetation. Rather than focusing on a single viewpoint, the trail rewards hikers with an immersive backcountry experience. Because trail conditions and access can change, Roamwise should prominently display live status updates and distinguish this trail from the separate Maunawili Falls route.
