Charles and I debated a little on what hike to take while visiting Oahu. I wanted to hike Diamond Head. He wanted to hike Koko Crater. Koko Crater looked a lot more challenging and Charles was pretty sure he had a broken toe so we ended up hiking Diamond Head. (yay!)
It is a fairly easy hike. There are a couple parts that are a little challenging, but it's really not that bad.
There are several scenic lookout stops. They all offered beautiful views!
