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.

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)
When researching the best and most popular hikes on O‘ahu you are bound to find mention of the Stairway to Heaven hike. This is a steep hiking trail including 3,922 steps span along O‘ahu’s Koʻolau mountain range.
Legal access to this hike is has been impossible for a few years now because of land use rights issues, but it remains a popular “forbidden” hike regardless. If you attempt to hike here, expect to be turned away or cited by Honolulu Police.
While the state is working on a way to make this hike a public attraction again, we ask that for now you don’t put this hike on your to-do list, but choose one of the other stunning hikes we list below.

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.
Why we like this hike: For the breathtaking coastal views from a well-paved trail leading to a cliffside lighthouse.

Local grinds: Head back into Hawai‘i Kai for a snack, drinks, and harbor views at Liko’s Tap & Table.
Lanikai Pillbox (1.8 miles)
Description: Also known as the Kaiwa Ridge Trail, the Pillbox hike gets its name from the leftover army bunkers that sit atop the hillside. The short but sweet trail gives you an overlook of Lanikai beach, Kailua beach, Waimanalo beach, and the Koʻolau coast.
Directions: Park in the Lanikai neighborhood (follow parking signs, as it is strictly enforced) and find the trailhead across from the Mid Pacific Country Club on Kaelepulu Driver.
Local grinds: Pop over to Lanikai Brewery after the hike for a local beer and a bite from one of its rotating food trucks.

5 Intermediate hikes
An “intermediate hike” means that the trail has some small challenges and that you should be in decent athletic shape and have some previous hiking experience before attempting. A little more effort, though, translates into a little better vantage point.
These hikes range from a classic – Diamond Head – to waterfall and ridge hikes. Our 5 favorite intermediate hikes are:
Diamond Head / Lēʻahi (1.6 miles)
Description: This iconic, heavily trafficked route goes to the top of Diamond Head on a paved road. Near the top, stair climbing is required. The payoff are sweeping views of the Koʻolau Range, the south shore, and a fantastic overlook of Waikīkī and Honolulu.

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)
Description: This big, demanding hike climbs more than 2,000 vertical feet to reach the top of Mt. Olympus and its beautiful valley views. Often wet and slippery, ropes are found on the trail to assist in climbing and descending.

Local grinds: Head down into Kaimuki for some ribs at the Surfing Pig.
Olomana (4.4 miles)
Description: This steep trail gains almost 2,000 feet on your way up to the first of three peaks that rise above the Windwardside. The views from the first two peaks offer the best vantage points of the Koʻolau range and the coast. While the first two peaks are relatively safe, peak three is very dangerous and it is not recommended to summit.
Why we like this hike: You get to sSummit a trio of steep peaks for personal glory (and unrivaled magnificent mountain views)

Local grinds: After this leg burning hike, kick back at Kalapawai Grill in Kailua for sandwiches and local plates.
Koko Head (1.8 miles)

Directions: The trailhead is located in Koko Head District Park. Note that the park parking lot is closed overnight (see hours here), so try to not to show up too early.
