Lulumahu Falls

Lulumahu Falls stands tall and tucked away up the Pali Hwy.  The trick to seeing this beautiful Oahu waterfall is actually finding it!  And that is only half your battle, as it's located on private property as well.  The waterfall is located near the Kaniakapupu Ruins, King Kamehameha III’s summer home.  What makes Lulumahu Falls one of the best Oahu waterfalls, is its impressive height and adventure getting there.

Nuuanu Reservoir

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!

Lulumahu Falls Hike

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.

Lulumahu Falls Path

About a 100 yards down, start looking for a path that branches off on the left hand side.  

Lulumahu Falls Hiking Steps

This will lead you to a set of mysterious stone steps.  Climb them and you see that they lead to an old reservoir.  Then follow the dirt trail on top towards the mountains.

Lulumahu Falls Hiking Path

Walk past the graffitied wall and around the fenced water pump, and look for a 2nd set of stone stairs.  Up top you will find another trail that will leads you forward towards Lulumahu Falls.

This part of the path will shortly end when it meets up with another section of the old water supply structure, where the stream meets up,  and water drops off 10 ft into a small pool.

If there’s an easy part to this Oahu hiking trail…it’s over!  From here the journey continues up river, hoping rocks and trying to walk along thin pathways of dirt.

Lulumahu Falls Hiking Ribbons

Look for ribbons tied to trees, which will help direct you to better position the side you’ll want to be on.  Be careful to not follow some ribbons that lead high into the hillside…stay closer to the stream.

The only way to get up to the waterfall is traveling slowly up stream.  If it’s raining or recently had heavy rainfall, do not attempt this hike this area, as the stream can turn into a rushing river, and can become very dangerous to travel through or alongside it.

The Waterfall

It takes about 15 minutes traveling up stream, until you reach the Hawaiian waterfall.
Make it up the stream, and you’ll have a grand 50 ft plus waiting for you tucked away in the middle of nowhere.

Lulumahu Falls Waterfall

There are very few Oahu waterfalls that you can hike to that deliver impressive heights…and Lulumahu Falls is quite impressive!

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. It 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 has endless supply of water cascading down the cliff.  That said, this waterfall only leaves a small pool of water behind.
