Had a lot of fun hiking this with my best friend and her two kids (1.5 and 9). Wear bug repellant. Views are beautiful, buildings are beautiful and show history. Parking is not fun. Be sure and stay in the dirt.

Heavily trafficked, not everyone makes it all the way up, the view is definitely worth it though.

the breeze and view at the top made it worth the hike up!

Crowded. However, it's cool once. It's fast and your in Hawaii.....

Love the view at the top but it’s always over crowded, even very early in the morning. It’s a quick hike with a big reward.

Loved every challenging minute of this hike! Great views all along the way and at the top. Lots of camaraderie on the trail.

Easy hike. Went around 8:30am on a Friday. Lots of people already. Spectacular views! Took us about an hour with stops for pictures. There is barely any shade so bring sunglasses, hats and water bottles!

Gorgeous easy to do hike that is child friendly and paved. Much harder “off road” hike down to the tide pools but definitely worth it (climb straight down rocks)

Crowded but pretty view
Child friendly
In the sun so bring water

very serious..but worth it..last time I went up was on my 50TH bday..let's go.
special note..its almost jus as hard going down lol

Every step was worth every second of the beautiful views.

Crowded

8/12/2018-Started at 0730 with tons of other people (parking lot in Diamond Head was full) so it was slow going to the top. The weather was sunny but not super hot yet and the view at the top wasn’t super crowded but the ocean was really pretty at least.

So glad we did this one. Tough climb and crowded the day we were there, but great camaraderie among hikers and terrific views at the top.

Came here for the tidepools. What an awesome experience! Should've paid attention to the directions, first headed down the wrong trail from the first lookout. Realized my mistake after scrambling down about 100 feet before deciding to turn back. The trail leading down to the tidepools was off of the third lookout. The way down was definitely more treacherous. Smaller kids would likely need a lot of help. But it was well worth it. By far the most memorable part of the trip for us. The tidepools were amazing with its wide array of fish. Nice reward for the work hiking down with a dip in the pool. The dragon nostrils were also impressive.
The hike back up was strenuous but easily doable. Made it back up in under 15 minutes.
Overall, this is must do for anyone looking for a memorable experience in Oahu.

Humid but not hot due to tree and then fog cover. Occasional fantastic views. Muddy, trail runners are okay. Overall great!:)

This hike is pretty fun for me. It may not seem interesting to look down at tracks the entire time, but there's enough change in steepness, distance of steps, and there's a nice visible drop midway through the hike to keep me entertained. The view is pretty good, both during (it's cool to look back and see how far you are) and at the top (360 view from the top of the crater).

I also wrote an in-depth review, take a look: http://www.thehawaiiplan.com/koko-head-crater-railway-trail-hike/

Definitely worth getting to the top!

A good alternative but much quiter and more lush hike is around the Makiki-Tantalus Trail System. There are 5 main points of entry into the interconnected system of trails - Judd Trail/ Nuuanu Trail from the Nuuanu Pali Dr., Maunalaha/Kanealole/Makiki Valley Trails via the Makiki Nature Center , Pu’u Ualakaa/Moleka Trails from Round Top Drive, Manoa Falls/Aihualama Trails at the end of Manoa Rd, and lastly Pu’u Pia/Kolowalu Trail from the end of Alani Dr/Woodlawn Dr. Study the trail map and have fun exploring.

Awesome hard trail

We had a great time climbing with my kids. I was put to shame by a mom climbing with her baby on her back.lol

Love, love, LOVE this hike!! Although, don’t be fooled, I wouldn’t say this hike is kid friendly and I certainly didn’t see any wild flowers. The view is absolutely incredible at the top. If you are a physically fit person and want to push your limits in physical activity... highly recommend doing this hike at least twice and seeing if you can beat your first time! Be sure to wear either hiking boots or trail running shoes. The terrain is uneven at points and a a lot of people who take a lot of time to get to the top... as well as narrow path and steep inclines at times. If you are trying to get a workout in without the frustration of slow folk either get there very early in the morning or near sunset.

I love Koko Head. I just did it carrying my baby a few days ago and just about died lol. Don’t carry a baby up the mountain if you want to use your legs the next few days!

Extremely crowded, as in traffic jam on the trail, even midweek. Very slow as people just decide to take a break in the middle the trail and block people in both directions.

The view at the top was nice but not worth dealing with all the people

if you are looking for your leg work out look no further. views are very nice, nothing you can't find on other hikes but definitely worth it

A nice hike! Easier than anticipated. It is all uphill and parts of it are through concrete tunnels- nothing small, enough room to move. The view wasn’t breathtaking- but a fun day hike !

We were there on a Thursday afternoon and it wasn't crowded. Dry, desert landscape, but the views at the top are awesome. We had the extra treat of seeing a hanger glider and a paraglider playing in the air right in front of us.
