The hike to the summit is well worth the view, even on a cloudy day. However, I wouldn't recommend going on a day when it's been raining. The trail is not maintained and can get very slippery at times. Definitely bring water and rest often. If you're not in shape, this trail is not for you.

If you're out of shape this hike is not for you. Trail is steep and sometimes dangerous. Bring water along as you'll be sweating by the time you finish.

I woke up this morning planning in going to Koko head. One thing i was not aware is that it takes 1 hour 1/2 by bus to get there. I was staying in Waikiki and was informed to take the number 22 bus which was 40 minutes delayed - quite a few people waiting for the same bus. So i gave up. i really wanted to go and I am just writing this review to give a tip for tourists wishing to go there. It is a long bus drive, plan accordingly and expect bus delays. it seems like the bus 22 doesn't run very often, i actually ended up walking along the bus route and only saw the bus a couple of times. Be aware that although the hike is not very long, better to get well organized about the transportation and your schedule.

I had the opportunity to work in Honolulu for about 8 months. While there, saw just about every corner of the island, but have to say, climbing this trail ("a natural stair stepper") was probably the most fun I had. Very strenuous workout as the inclination at some points is as much as 50 degrees and part of the trail is actually a railroad tressel over a 20 foot deep gorge on the side of the mountain. First time over was one of the scariest feelings ever, but when you do it, you have such a great feeling of accomplishment! The views at the top (where there is an abandoned lookout post [from WWII] are amazing...HOnolulu to the west, Hanuma bay to the south. Just phenomenal. BTW its free. Plenty of parking at the base of the trail. Usually a bunch of people on the trail so if you need some help, there's usually someone there. Just do it if you want a challenge and are physically active.
