'Aiea Loop Professional Guide
Detailed Trail Description from our Guidebook
"This relatively level loop just above Honolulu is high enough into the foothills of the Ko’olau Mountains to feel wild and is a great favorite with both locals and visitors. In fact, it can be crowded on weekends. The route offers some interesting views and a variety of tropical trees and flowers.
Like most of the trails on the (geologically) older islands, this one can be muddy and slippery when wet. The trailhead has water, toilets, picnic facilities, and a heiau to visit as an added bonus. You can hike this trail in either direction, but most people prefer to start at the upper end and wind up at
the lower, so that is how it is described here."
