Maunawili Falls Trail is a popular hiking destination on Oahu, Hawaii, leading to a picturesque waterfall and swimming hole. The trail is approximately 5 miles round-trip, with an elevation gain of about 1,350 feet, and typically takes 5-6 hours to complete.

Access the trail via the Maunawili Demonstration Trailhead off the Pali Highway; note that the former neighborhood access is closed, and trespassing can result in a $1,000 fine. Parking is limited and has a two-hour restriction, so consider carpooling, using a ride-share service, or arranging a drop-off.

The hike begins with a gradual uphill climb through lush forests, featuring boardwalks to assist with the ascent. After approximately 1.7 miles and a 600-foot elevation gain, you’ll reach a junction with the Maunawili Falls Trail.

From the junction, descend 0.75 miles (about 20-30 minutes) and arrive at Maunawili Stream. The trail crosses the stream multiple times; many hikers opt to walk upstream, rock-hopping as they go.

After 0.1 miles, you’ll reach the waterfall, where you can swim in the deep pool beneath the falls. Local youths often perform acrobatics into the pool, adding to the lively atmosphere.

This trail is suitable for active families with children aged six and above. However, be prepared for muddy and slippery conditions, especially after rainfall. Wear sturdy footwear, bring ample water and snacks, and always pack out all trash to help preserve the trail’s natural beauty.
