This unsanctioned Oahu hiking trail will take you on an adventure
through old hunting grounds, a dense bamboo forest, up concrete steps
in the middle of nowhere, along the Nu’uanu Reservoir, through a
stream, across giant rocks, and alas
an amazing 50 ft plus waterfall!
The adventure starts at the end of the Old Pali Road, where the highway meets back up.
There are a couple entry points in this area. The first entrance is walking through a big hole in the fence at the water supply board. Make sure you read all trespassing signs and be warned, before preceding the hole on the side.
There is also an old hunting station that marks the start of this Oahu hike to the Lulumahu Falls, around the corner off the Pali Hwy.
The hunting trail narrows and winds until you reach the stairs. The Honolulu Water Board Supply gate starts off on a road with lots of bamboo towering above. The further you travel down the path the narrower it becomes. You will notice the bamboo starting to close in as the trail narrows.

This will lead you to a
set of mysterious stone steps. Climb them and you see that they
lead to an old reservoir.

the graffitied wall and around the fenced water pump, and look for a
2nd set of stone stairs. Up top

This Hawaiian waterfall has a beautiful presence, as it sits back in a narrow canyon with vines cascading down the walls, and narrow light shining from above.
Avoid scaling the walls or climbing to the top of the waterfall that is dangerous and can result in serious injury or other consequences.
It rains quite often in the Pali region, and the mountains are
continuously soaked. It seems that Lulumahu Falls are in endless
supply of water cascading down the cliff. That said, this
waterfall only leaves a small pool of water behind.

earlier in the morning to help avoid any occurrences.
Drive a little further up the highway and check out the famous Pali Lookout, where King Kamehameha fought one of his final battles in the tall cliffs.
Today you can visit the lookout and admire one of the
most amazing views of the Windward Coast…that is if the whipping winds
don’t blow you off the mountainside.
Better known as King Kamehameha III summer home, these ruins are
close to the Lulumahu Falls entrance.

left to the 1847 structure, but a strong presence where 10,000
Hawaiian once gathered.
