Beautiful hiking trail, partly very muddy

As much as this is a Cliff Trail, most of the walk is surrounded by foliage. It's a beautiful walk through bamboo and tall red trees with spongy soft bark?! Once you are up on the ridge there are so many options to extend your walk down to Round Top and back Manoa Falls.

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!

Manoa Falls is one of the most spectacular waterfalls on Oahu to see! The fall is 150 feet tall and cascades down into a lush jungle. You can swim in the pool formed at the bottom to cool off! If you enjoy climbing and seeing the less-traveled roads, Lā-'ī Road and Waiomao Road can help you sneak in that little bit extra!

ʻAihualama Falls Trail leads through the Lyon Arboretum and has many side trails that all lead to the same destination in the end. No matter which way you choose, the trail through the jungle is mostly flat, well maintained and easy to walk.
