Awesome hike. It took us two hours but every minute was absolutely worth it. It can get a bit slippery at places. So wear good shoes and watch your step.

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.

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.

I finished this in a little under 2 hrs barefoot. I was able to run a good portion of it. Great leg and cardio workout with beautiful views and plenty of birds to sing to you.
