The waterfall itself is beautiful with the thick jungle and mossy backdrop. The mosquitoes throughout Lyon Arboretum and the ʻAihualama Falls Trail are pretty bad!

Usually, you can watch the water running down a beautiful rocky and moss covered wall at ʻAihualama Falls. Depending on the recent amount of rain in the valley, they might be dry or carry a lot of water!

Reaching Luaʻalaea Falls might be a little harder than nearby Mānoa Falls, but thanks to its lesser popularity, there's a good chance that you will have the entire waterfall to yourself or just share with a handful of people. The waterfall itself is beautiful, especially if there was some rain before, and is a great spot for a little refreshment under the falling water.

Caution: Pretty dangerous trail for beginners. Very muddy, slippery, overgrown and sometimes you have to climb steep walls. Scheduling, KM and GPS tracking does not seem to have been recorded correctly by Komoot either. It's slow going here. Definitely plan more time.
