Just a quick drive from Waikiki Beach off the Pali Highway you'll find one of Oahu's pristine waterfall trails "Lulumahu Falls". The Lulumahu waterfall is located near the Kaniakapupu Ruins, once King Kamehameha III’s summer home. This trail is about 1.7 miles long and can take anywhere from 30min to an hour depending on your pace.
We'd consider this a mid-level hike.
Getting to Lulumahu Falls
There are a few ways to get to this trail, the best way is to drive. Don't worry if you are without a vehicle, the public bus (bus schedule) will drop you off close to the trail head, the walk is beautiful. For the visitors driving there parking is limited so come early if you can.
From Waikiki, take the H-1 Freeway headed west, Take the Pali Highway (Highway 61), More Scenic Drive Take the Old Pali Road exit (Nuuanu Pali Dr) Follow the Old Pali Road until it loops back onto the Pali Hwy. Park off to the side of the road or in front of the trail head. The Board of Water Supply gate is located in this area.
Entrance To The Falls
The entrance of the trail starts off wide and open. There are bright colored markers every few hundred yards that will let you know you're going in the right direction. The first part of the trail you'll have to walk through the bamboo forest. Keep on the Lulumahu Trail. 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.
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.
