Mount Olympus via Wa’ahila Ridge: Elusive Views but Is It Worth It?

When you’ve lived in Hawaiʻi long enough, you learn that some hikes love to hide behind the clouds.

That’s been my experience with Mount Olympus (Awaʻawaloa), rising to 2,598 feet above Honolulu. I’ve hiked it twice now, and I’m still waiting for a fully clear summit day.

This sub-6-mile ridge hike isn’t beginner-friendly. But if you’re after a solid workout, fewer crowds, and sweeping views of Honolulu and the Koʻolau Range (weather permitting), this trail delivers.

Mount Olympus Trail Stats

Is This Hike Right for You

Mount Olympus isn’t the most technical ridge on Oʻahu, but it will test you. Between mud, scrambling, route-finding, and heat, this hike can feel much harder than the mileage suggests.

A good fit if you:

• Have done a few ridge hikes on Oʻahu
• Are comfortable scrambling and using your hands
• Have good traction footwear
• Can sustain 4–6 hours of effort in humid conditions

Not a good fit if you:

• Are new to hiking on Oʻahu
• Avoid mud, steep terrain, or overgrown trails
• Are hiking only for guaranteed views

Trailhead & Parking (Waʻahila Ridge)

The most common route to Mount Olympus starts at Waʻahila Ridge State Recreation Area in Honolulu. The park is typically open daily from 7:00 a.m. to 7:45 p.m.

Getting there can feel confusing the first time. You’ll drive through a wooden gate and down a narrow paved road that looks like it might be pedestrian-only. It’s not.

At the end, you’ll find a large parking lot surrounded by tall pine trees, with picnic tables and roosters wandering around. It feels more like Kauaʻi than Honolulu.

Amenities:

• Restrooms (rare win for Oʻahu trailheads)
• Boot wash station
• Picnic areas

Important: This is a known high-theft area. Don’t leave valuables in your car but personally, I’ve never had any issues here.

What to Expect

This trail throws a bit of everything at you: mud, roots, overgrowth, ridge exposure, and a steeper, rope-assisted push near the top.

Forest Start: Mud, Roots, and Pine Needles

You’ll begin in a shaded pine forest before transitioning onto a ridge. Early on, expect mud, exposed roots, and slippery footing, especially after rain.

You’ll pass a graffiti-covered utility tank before things start getting more interesting.

First Junction + Saddle Descent

Not far in, you’ll reach your first split. Follow the sign and go left.

---

Shortly after, you’ll drop into a saddle with some big boulders and steeper sections. It’s fun going down, less fun coming back up.

Exposed Ridge + Overlooks

Once you climb out of the saddle, the trail opens up.

You’ll start getting wide views of Honolulu and the Koʻolau ridges, with less shade and more exposure. On hot or humid days, this section can feel intense.

---

The ridge narrows in places and is overgrown with uluhe fern and dense vegetation, brushing against your legs and arms.

We walked into a perfectly intact spiderweb across the trail which probably meant no one had been out here in a while.

Key Junction + A Treat

You’ll reach a second junction marked by an “End of Maintained Trail” sign. Go straight up. The trail to the left leads down to Kolowalu / Puʻu Pia.

If you are hiking between August and December, don’t miss strawberry guava right next to this sign. It’s my favorite trail snack but keep in mind that in Hawaiʻi, unwashed fruit can carry parasites linked to rat lungworm disease. Enjoy at your own discretion.

Final Push: Ropes + Scrambling

As you approach the summit, the trail steepens again.

You’ll encounter:

• Rope-assisted sections
• Scrambling over dirt and rock
• More overgrowth

Highly recommended:

• Gloves
• Long pants

Summit

By the time we reached the summit, the Windward side was completely covered in clouds. We couldn’t see much in that direction, but the shifting cloud wall moving over the ridge was pretty incredible to watch.

Thankfully, the Honolulu side stayed open. We had clear views of Diamond Head, the city, and surrounding Koʻolau ridges. It was also my first time spotting Kaʻau Crater from this side.

---

We stuck around for a while hoping things would open up, but the clouds weren’t going anywhere. No complaints though since we had the summit completely to ourselves.

Conditions and Reality Check

This trail changes a lot depending on the weather.

After rain, expect more mud and slick sections, especially around roots and steeper parts. It slows you down and makes the climb feel harder than it should.

On cloudy days, you might get some shade, but it can feel like a sauna. The air gets thick and humid, and unless you catch a breeze, it doesn’t cool off much. I went through all my water, electrolytes, and salt tabs on this hike.

Views aren’t guaranteed either. Clouds can roll in fast and block the views completely, even if it starts out clear.

My Experience

This was supposed to be a group hike, but everyone canceled at the last minute because of the weather. In the end, it was just me and a friend.

We went a few days after the third Kona Low storm, so I was expecting zero visibility, just like my first time hiking this trail, but the shifting clouds made it even more memorable.

We were covered in mud, soaked in sweat, and definitely questioning our decision-making skills at times, but it was one of those hikes that sticks with you.

I’m still chasing that fully clear summit day 🤞, but honestly, even without it, Mount Olympus is worth doing if you’re up for a challenge and don’t mind a little unpredictability.

Nearby Hikes

If you’re trying to decide whether Mount Olympus is the right fit, here’s how it compares to a few nearby ridge hikes:

Kuliʻouʻou Ridge (East Honolulu)

4.8 mi | 1,800 ft gain

Kuliʻouʻou is a great intro to ridge hiking on Oʻahu. The trail is well-maintained, with a steady climb through forest before opening up to wide ridge views. You’ll still get a solid workout, but without the overgrowth or significant scrambling that Mount Olympus has. If you’re newer to ridge hiking or want something more straightforward, this is a solid option.

Mānoa Middle Ridge (west of Mount Olympus)

~4.2 mi | ~2,300 ft gain

Mānoa Middle doesn’t hit you right away, but don’t get comfortable. Most of the elevation gain comes in the final mile, where you climb about 1,600 feet in a steep, sustained push. It’s a brutal finish.

Navigation can be tricky in sections, especially higher up. Compared to Mount Olympus, it’s shorter, but feels more intense because of how quickly the elevation gain hits. The reward is wide, 360° views once you reach the ridge.

Kaʻau Crater Loop (east of Mount Olympus)

5.6 mi | ~2,000 ft gain

Kaʻau Crater is probably the most similar hike to Mount Olympus in terms of overall effort. It’s is a local favorite for a reason. You get waterfalls, a crater basin, and a ridge all in one hike.

It’s a long day and feels more adventurous, but if you like Mount Olympus, you’ll likely enjoy this one just as much.
