This was a great quick hike up to a beautiful view. I wouldn't recommend doing it after heavy rain because it gets slippery. Once you're at the top there are more connecting trails if you wanted to continue, or you can just trek back down. At the top there are 2 different look out points (pillboxes).
Great piece of history, There is a steep jaunt toward the beginning, there are ropes to hold when its wet and slippery, but up on the ridge its flat the rest of the the time. There are actually two pillboxes, so look for them both, and a few hidden underground rooms not to far off, but they are flooded out.
Love it, so beautiful. There is actually two great spots for amazing views, but you have to find the short little off shoots for both of them that lead to clearings to see out over the valley, they are both kind of hidden. I used to Run this trail every morning when I loved in Pupukea, absolutly perfect for a nice 45 minute run, never gains or loses elevation to much. Do not let the gate and warning signs at the entrance scare you, it is accessible to the public, though during the week you might run into some military exercises on the pupukea range, and it is also a very popular hug hunting location. Like all other trail-head's on Oahu, don't park here with a rental car, you have a high chance of getting broken into. Make you car look like a North Shore car, beat up with lots of stickers, and they will leave you alone :)
Pretty easy hike. Did it with our 8 year old son. Wear good shoes, there might be some pretty good mud on the hill straight up. There are a few ropes to help but some have been broken. Pillbox was nice and so were the views. It was a pretty nice afternoon hike. This hike is also listed under the name of Kammiland Trail.
