From Honolulu take H1 West to exit 10. Take a right onto Waimano Home Rd. Then go left on Komo Mai Dr. Take Komo Mai all the way to the end where the circle is. You will see a gate, just park on the road and go past the gate. Follow the main trail for about .5 miles until you find a sign/marker. Part of the sign will say "Waimano Falls 3/4 mile" Follow it to the right down the steep hill and follow the small trail all the way down the valley. At the end is 3 pools, one huge one with a big waterfall, a really small one, and the last one which has 15-20 foot cliffs to jump from on the sides, and even a rope swing.
