Create an itinerary including Koko Crater Railway Trail
Climb up 1,048 railroad ties along Koko Crater Railway Trail to reach the summit of this Hawaiian crater, famous for its views and a large botanical garden. The rail ties were installed over 60 years ago to help carry military supplies to bunkers at the top. Today, it's a popular hiking and running spot. From the summit, you can see three islands on a clear day. Be careful because certain parts of the railroad path are crumbling, and some are quite steep. Bad weather can make the hike dangerous. Take plenty of water and supplies, use good shoes, and bring sunscreen.

  • This hike is no joke. My husband and I hiked it in an hour and forty five minutes. It’s difficult both going uphill and down due to the steepness and incline that starts about 40% into the journey. Make sure you have good shoes, sunscreen on (although you’ll sweat it all off), a hat, and LOADS of water. We went through 4. If you’re afraid of heights don’t do the hike - there’s a portion of the train track that has no dirt immediately under it. Just large gaps - it was terrifying but I bear crawled through it! We took breaks quite frequently when the steepness grew and I’d like to say the view is worth it but we were so tired we couldn’t even take it in. I don’t exercise but am slim - that’s not enough 😂 It rocked both of us in which my husband even works out and he wanted to quit! I forced him to continue as I didn’t want to potentially slip and die on the way down while alone! Looking back on pictures the view truly is breathtaking. There’s one small spot of shade up top so grab your breath there and once calm hike the top bit to the outlook. Very proud to say I accomplished it but damn did it almost kill me! Easily the most gruelling hike I’ve ever done but worth it just to say I completed it!
  • Went today at 8 with good cloud cover. Great hike but you need to be in shape. It's pretty steep and you can take breaks along the way. Beautiful views at the top. We finished just as Sun came out and many headed up as we were leaving. Pretty surprised to see those starting so late and in full sun, many with young kids in tow. I think this would be too hard for many young kids unless they are very athletic and in shape. Bring lots of water. Overall lovely but a tough workout.
