Maunawili Trail

No, the Maunawili Trail (also known as the Maunawili Demonstration Trail) is distinct from the popular Maunawili Falls Trail. While both are on O'ahu, this trail generally follows the base of the Koʻolau Mountains and is much longer. The Maunawili Falls Trail has been closed for construction and planning since mid-2025, with no official reopening date announced. However, the Maunawili Falls are still accessible as a highlight along this longer Maunawili Trail route.

Komoot rates this route as difficult, primarily due to its significant length. It's a long, one-way hike, typically 9 to 10 miles, with an elevation gain of around 670 meters. While the initial sections from the Pali Highway trailhead are relatively easy, the middle can be more challenging with slippery, narrow, and overgrown paths. Expect it to take 5-7 hours to complete.

The terrain is varied. You'll find yourself immersed in dense, lush tropical forests. The path can be very muddy and overgrown in sections, with exposed tree roots that become extremely slippery when wet. There are also occasional stream crossings. Despite being mostly flat, its length and these conditions contribute to its difficulty.

You'll be surrounded by a vibrant tropical rainforest with canopies creating a cool atmosphere. The trail offers incredible views of the steep cliffs of the Koʻolau Range and the beautiful Windward Coast, including panoramic glimpses of Waimanalo. After heavy rain, you might spot several seasonal waterfalls along the route. Keep an eye out for the Viewpoint and the iconic Maunawili Falls.

The Maunawili Trail can be accessed from various points. A common starting point is near the Pali Highway. Parking information can vary, so it's advisable to check current local conditions before heading out. Public transport options to the trailheads are limited, so a car is generally recommended.

The Maunawili Trail is located within the Ewa Forest Reserve. Generally, day-use permits are not required for hiking on established trails in Hawaii's State Forest Reserves, nor are there entrance fees. However, regulations can change, so it's always best to check the latest information from the Hawaii Department of Land and Natural Resources (DLNR) before your visit.

Yes, dogs are generally allowed on the Maunawili Trail. However, they must be kept on a leash at all times. Given the trail's length, muddy conditions, and potential for slippery roots and stream crossings, ensure your dog is fit for a long hike and that you bring enough water for both of you.

O'ahu's weather is generally pleasant year-round. However, the trail can be extremely muddy and slippery, especially during the wetter winter months (November to April). The drier summer months (May to October) might offer slightly better conditions underfoot, but rain can occur at any time. Always check the weather forecast immediately before your hike, as flash floods are a real threat after heavy rains.

Given the trail's length and conditions, essential items include plenty of water, sturdy hiking shoes with good grip (expect them to get muddy), insect repellent, sun protection, and rain gear. A first-aid kit is also highly recommended. Consider bringing trekking poles for stability on slippery sections and stream crossings.

Yes, the route primarily follows the Maunawili Trail, which makes up about 80% of the path. However, it also passes through sections of the Maunawili Falls Connection, the Maunawili Ditch Trail, and briefly touches upon the Maunawili Falls Trail.

While there aren't establishments directly at the trailheads, you'll find various cafes and restaurants in the nearby towns of Kailua and Waimanalo. These towns offer options for a meal or coffee before or after your hike, typically a short drive from the trail access points.
