Waipuilani Falls Hike

1.9 miles 688ft elevation Out & Back Trail Moderate

The Waipuilani Falls Hike is a hidden jungle trek in the Koʻolau Mountains, featuring a beautiful, secluded waterfall deep in the rainforest. This off-the-beaten-path adventure requires stream crossings, rock scrambling, and some route-finding skills, making it ideal for those looking for a remote and rewarding experience. Important Notes: Navigation can be difficult. Multiple stream crossings so expect to get wet. Muddy and overgrown sections so be prepared for thick vegetation and slippery footing. The hike begins in Nuʻuanu Valley, near the Pali Highway area. Mid-Hike: The trail follows Waipuilani Stream, requiring multiple crossings over slippery rocks. Certain sections are steep and may require rope-assisted climbs. The trail becomes narrower and more rugged as you approach the falls. The waterfall cascades over a moss-covered cliff, creating a peaceful and secluded spot deep in the valley. The pool at the base is shallow, but it’s a great place to cool off and take in the natural beauty. Flow varies depending on rainfall. It may be a trickle in dry months or a strong cascade after recent rain. Descent & Return: Retrace your steps back through the stream and jungle. The full hike takes about 3 to 4 hours round trip, depending on trail conditions and stops.

Tips for Hiking

Best Time: After light rain, but not during storms.
Early Morning: Cooler temps, fewer people.
Midday: Best lighting for photos, but hotter.
Late Afternoon: Peaceful, but avoid hiking too close to sunset.
Avoid hiking after heavy rain: The stream can rise quickly, making crossings dangerous.
Wear waterproof hiking shoes: Slippery rocks & stream crossings.
Bring bug spray: Mosquitos are heavy in the jungle.
Use trekking poles if needed: Helpful for balancing in the stream.
Carry extra socks & towels: Your feet will get wet.
Download offline maps: The trail is unmarked and can be confusing.
Check weather before going: Flash floods are a serious risk.
Parking: No official parking lot so park legally on nearby streets near Nuʻuanu Valley. Be respectful of residents and do not block driveways.

Thoughts from my Hike

This was a pretty descent hike. Plenty of parking at Pali Lookout. To get to the trailhead, you walk back down the entrance road a couple hundred feet and look to the left for the entrance. The trail was marked okay, but I tend to rely more and more on AllTrails these days. A lot of trail markers have fallen off or been removed. No real views along the way. It's a hike through the woods all the way. The falls were not running that strong, but it was still a great scene. There was also a creepy cave that you can climb up to and go in. It doesn't go too far in thankfully as it reminisced scary movies "Don't go in the creepy dark cave!"
