As the second-oldest island in the present-day chain (2-3 million years old), O‘ahu has aged beautifully. Millions of years of erosion have whittled away at its volcanoes, creating the dramatic, spine-like peaks and ridges we see today. Some lush and shaded, others dry and exposed, Hawai‘i’s micro-climates create a diverse range of ecosystems to walk through, many with, of course, ocean views.m
To help you find the right hike for you and your traveling companions, we mbreak down some of the island’s best hikes below, into groups of easy, intermediate, and advanced.
Related guides: Most people coming to Hawaiʻi visit multiple islands to make the most of the long trip needed to get here. If this is you and you are into hiking, we highly recommend our hiking series for the other islands.
Hiking and safety tips
We rate our recommended hikes in general terms and, as with any outdoor activity, one should be aware of their own limitations and abilities before attempting. Please be respectful of local residents when hiking. Don’t trespass, don’t park illegally, and don’t leave valuables in your car. Bring plenty of water and snacks on the trail, wear proper footwear, and watch the weather, as conditions can change rapidly (we recommend always bringing a rain jacket).
The Haʻikū Stairs / Stairway to Heaven hike (temporarily? closed)

We show the trailheads of all 15 hikes discussed here on the map below. Keep reading for descriptions, directions and specific tips for each of the hikes.
5 Easy hikes
What do we mean with an “easy” hike? In this case, it means that the hike is mellow, doable for the everyday person and families with kids.
Some of the best bang-for-buck hikes on O‘ahu fall under this category, like the Makapuʻu Lighthouse Trail and the Lanikai Pillbox – great for all abilities, with views that rival any advanced trail. Our 5 favorite easy hikes are:
Makapuʻu Lighthouse Trail (2.0 miles)
Description: This paved trail is great for families. It’s a mellow climb to the Makapuʻu Lighthouse and an overlook of the southeast part of the island, one of the best bang-for-buck hikes in terms of its accessibility and payoff. On clear days, you can see the islands of Molokai, Lanai, and Maui in the distance.

5 difficult (but rewarding!) hikes
If you’re looking for a physical challenge and a longer day on the trail, this section is for you. “Difficult” means you should be in above-average athletic shape, have previous hiking experience, and be ready to spend most of the day on the trail.
Though the distances are not extremely long, the elevation gain and trail conditions (mud, rocks) can make things challenging. But those willing will be treated to some of O‘ahu’s most rugged and beautiful wilderness, including the highest peak on the island, Mt. Ka‘ala.
Our 5 favorite difficult hikes are:
Mt Olympus (5.2 miles)

Why we like this hike: You get to sSummit a trio of steep peaks for personal glory (and unrivaled magnificent mountain views)
