Waipuilani Falls, also known as Twin Pali Falls, is a hidden gem tucked away in O‘ahu’s Nuʻuanu Valley. This 50-foot waterfall offers a scenic and peaceful hike through lush forest landscapes, with a serene pool at the base of the falls perfect for a refreshing break. The trail is around 1.9 miles round trip, making it a moderate hike that takes about 1 to 1.5 hours to complete. As you hike, you’ll pass through bamboo groves, cross streams, and navigate sections of dense vegetation, immersing you in the natural beauty of the island.

To get to the trailhead, drive up Pali Highway to the Old Pali Road intersection. From there, walk a few hundred yards toward the highway, and you’ll find an open dirt patch on the left side of the road, marking the trail’s starting point. The hike can be muddy, especially after rainfall, so it’s important to wear sturdy, water-resistant footwear. The trail can be a bit tricky, especially with stream crossings and potential for getting lost, but using the AllTrails app can help guide you along the way.

Parking is available near the trailhead, but spaces fill up quickly, so it’s recommended to arrive early. The trail does not have any facilities, so be sure to bring water and snacks for the hike. While the hike itself is challenging, the sight of the twin waterfalls cascading into a tranquil pool is well worth the effort, offering a peaceful spot to relax and take in the natural surroundings.
