There is no shortage of stunning hiking trails on Oahu. From popular trails with more people than you can count to more serene destinations where it's just you and nature, there's something for everyone. This is a list of some of my favorite hiking trails on Oahu. I have personally completed these hikes and have found them all to be very enjoyable and photo-worthy.

Recommended Hiking Gear

As a rather risk-averse hiker who is wary of heights, the first two hikes were somewhat easy for me. The latter was truly difficult and I had a hard time making it to the top and back. If you too are not much of a hiker, know that there's absolutely no shame in turning back if at any point you feel uncomfortable. No hike is worth risking your health and safety. On that note, do make sure you are duly prepared with proper hiking equipment. This alone can make your hiking experience much safer and more enjoyable.

Makapu'u Point Lighthouse Trail - Very Easy

This is a pretty popular trail that can at times seem crowded if you judge on parking availability alone. But to be fair, the parking lot to this trail is on the small side, and it's actually ok to park your car on the side of the road just outside of the gates. Even if the parking lot seems full, don't be deterred. Makapu'u Point is quite large with many little side trails so it doesn't feel very crowded. The main trail is nicely paved, allowing for baby strollers and those in wheelchairs to access the top. But it is a somewhat steep climb. The view at the end is such a reward and worth the hike. Makapu'u tidepools can also be accessed from this trail, although that path isn't paved and requires a bit more agility.

Kaena Point Trail - Easy

The easiest hiking trail I've done on Oahu has to be Kaena Point Trail. It's roughly 5-miles long (roundtrip). The terrain is flat and there's little to no descent. It winds along the westernmost coast of Oahu leading to a nature reserve where you can see seabirds (mainly albatross) and large Hawaiian monk seals in the wild. Since there are two different trails, this hike is rarely crowded and is one of those "off the beaten path" trails.

Lanikai Pillboxes - Moderate

A moderate Oahu hiking trail is the now popular Lanikai Pillbox hike. Located on the windward side, this hike is actually quite short, but it involves a quick, steep ascent. It's not terribly difficult, but those with a fear of heights and poor balance may have issues. The reward comes rather quick in the form of a stunning panoramic view of Lanikai and Kailua Beaches. This hike can be somewhat crowded, but traffic is restricted by the difficulty in finding parking in this area.

Koko Crater Trail - Difficult

By far the hardest hike I've yet to do on Oahu is Koko Crater Trail. From what I've read, there are many other hikes that are much more difficult but I warn you again that I'm not much of a hiker. So for me, Koko Crater Trail exceeds my comfort zone by a lot.

This trail is short (under 2 miles), but it's very steep. It also involves climbing old railway tracks that now serve as makeshift stairs. Except these stairs are much longer and taller than the ones that modern humans are used to, so they're not terribly easy for those of us with shorter legs. But like Lanikai Pillboxes, the reward is in the panoramic view at the top. So in that sense, Koko Crater is worth doing at least once.
