It's really steep! Start early in the morning! You need to be sure-footed!

Fantastic panoramic views! You definitely need a head for heights and surefootedness! It's very steep! Be sure to do the hike early in the morning and only if it's dry, as the wooden planks can be slippery.

This is not for everyone. It is very hard, and one should be fit to enjoy it. It is not like walking up a hill; on a trail one can choose the length of their step. Walking up railway ties, that is not an option. Walking up requires strength and wind, walking down requires not being exhausted from the walk up, and a pair of very strong knees. Again, this hike is only for the fit.

Formed within a volcanic cone, Hanauma Bay is a very popular tourist destination. There is world class snorkeling (check Groupon for discounts) and the conservation area makes it great for hitting the trails!

From this lookout above the Nature Preserve, you get a really nice overview of the beautiful blue ocean, circled by vertical crater cliffs.

This section of the climb is flat but holds another challenge. The bridge crosses a 40 feet drop, so if you're afraid of height, you better take the bypass that was created for those who want to avoid the bridge.

Koko Head Stairs includes over 1,000 steps before you finally reach the top of Koko Crater. While climbing the stairs of the abandoned railway, you will gain about 880 feet in elevation. Most certainly a tough hike but a great workout with a rewarding view as well!
