Thanks for all of the suggestions. I decided to choose jeronij's waterfall lots because they are the closest I could find to recreate the falls. It's a bit too wide and hard to tame, but it does have good effects.
After a one and a half mile hike in the Manoa Valley, you'll reach the 150 foot tall Manoa Falls.
At the bottom of the falls are many boulders that have fell from further up the mountains. The water here flows down the Manoa Valley as the Manoa Stream, all the way down to the Ala Wai Canal in Waikiki, and eventually into the Pacific Ocean.
Until next time, take care!
