Experienced hiker and trail runner. Had a blast on this trail. The trailhead is at the top of a neighborhood resembling San Francisco with its steep, winding streets. The trail is mostly shaded with many overlooks and spots to stop for scenic views. Parking is free and no charge to enter. There are restrooms at the recreation area and trailhead.

Beautiful loop that takes you along the Ridgeline on Aiea Trail. Tons of trees and different terrain. Small narrow path was muddy and messy but totally worth the views!
Solid 2+ hours for full 4.8 mile (5mi back to car) plan on getting dirty!
I have hiked my entire life I started the hike around 330pm and with a few stops along the route at a walking pace I made it back around 6pm as the sun was setting.
It rained a few times during the hike trail gets very slippery and muddy! Be safe and have fun!

One of my favorite trails on the island for the views, length and ambiance. Careful for mud though!
Being a morning hiker we got there around 6am, the gate is still closed off so we had to park about half a mile away on the street. Then it's about a mile from the parking spot to the actual trail. It kinda teases you Abit since you'll pass like 3 separate parking spots on the way to the trail. You can either choose the upper starting path or the lower (By the recreational area) we chose the upper path.
Overall the trail was nicely kept and even a few spots to take a break. About 1/3rd of the way you'll have the branched path to the ridge, haven't tried that yet though. 1/2 way through you'll get to the H3 lookout which is gorgeous (see pic). Around the last leg was the only funky part with a ton of mud and slippery spots, so definitely bring a hiking stick and good/waterproof shoes!
All in all, the trail is one of my favorites so far. I highly recommend if you want a nice lengthy, but not too challenging trail.

Solid trail. Very well maintained, amazing views (especially early in the morning). The trail is dog-friendly and there are also a lot of joggers and families walking the trail. Something for everyone. There are bathrooms available and ample parking. Open 7am-6:45pm

I joined a hiking group and climbed the mountain together. One participant knew the place well so we listened to him. We had a good view. I was surprised to see some barefoot runners.
