1. Slieve Bearnagh Summit Trail

Starting with the classic: the summit trail. This route is perfect if you want that triumphant feeling of reaching the top. The path winds through rolling hills and rocky outcrops, gradually ascending to the peak. Along the way, you’ll see the Mourne Mountains stretch out like a painter’s canvas—rolling green valleys, jagged ridges, and sparkling streams.

The final push to the summit can be a bit steep, so bring proper hiking boots. Trust me, your knees will thank you. Once at the top, the 360-degree view is something that you truly need to see to believe. On a clear day, you can even catch a glimpse of the Irish Sea.

2. Slieve Bearnagh Ridge Walk

If you love the thrill of walking along dramatic cliffs with drops on either side, the ridge walk is for you. This route runs along the sharp ridges of Slieve Bearnagh, offering views that photographers dream about. The path requires a steady footing and a bit of courage if you’re afraid of heights, but the scenery is well worth it.

You’ll pass through heathlands and rocky outcrops, and if you’re lucky, you might spot some mountain hares or birds of prey gliding overhead. The ridge walk is ideal in the morning when the mist is still clinging to the valleys—it gives the landscape a mysterious, almost otherworldly look.

3. Slieve Bearnagh Loop Trail

For those who like a mix of challenge and variety, the loop trail is perfect. It combines parts of the summit trail with winding paths through valleys and along streams. This route is long enough to feel like an adventure but manageable in a day. Along the way, you’ll find secluded spots perfect for a picnic or just pausing to enjoy the quiet.

The loop trail is one of those hikes that really gives you a sense of accomplishment—you’ve seen the mountain from multiple perspectives and explored areas that most visitors miss.

4. Donard Brook to Slieve Bearnagh Trail

This trail starts at Donard Brook, following the water upstream before winding into the mountains. The sound of flowing water is incredibly soothing, and the shaded paths under the trees provide a welcome break from the sun. As you climb, the brook eventually disappears below the horizon, replaced by the sweeping rocky slopes of Slieve Bearnagh.

This hike is ideal if you enjoy combining nature’s sights and sounds. You’ll cross wooden bridges, hop over small streams, and pass waterfalls that make the perfect photo opportunity.

5. Bloody Bridge Route

Despite its intimidating name, the Bloody Bridge Route is a must-explore trail. The path begins at the base of the mountain and meanders through dense forests and mossy rocks before opening up to incredible views of the surrounding peaks. The “Bloody Bridge” itself is a historic site with a story you’ll want to read about when you get there—it adds a layer of intrigue to the hike.

This route is moderately challenging, and the mix of greenery and rocky slopes keeps it visually interesting. It’s a favorite for anyone who loves hiking with a hint of adventure.

6. Raven’s Rock Climb

If you’re seeking a more rugged experience, the Raven’s Rock route offers some climbing challenges along the way. This path is not for beginners, but for those with a bit of experience, it’s thrilling. You’ll scramble over boulders and navigate rocky ridges, but the reward is unparalleled: panoramic views of valleys and peaks that stretch as far as the eye can see.

Bring gloves and good shoes, and don’t rush. Taking your time to enjoy each view makes this trail one you’ll truly love to explore.

7. Slieve Bearnagh Eastern Ascent

The eastern ascent is often quieter than the more popular western trails, making it perfect if you want a peaceful hike. The path meanders through heather-covered hills and open slopes, offering uninterrupted views of the Mournes. You’ll notice how the colors change as the day progresses—golden in the morning, soft and muted by afternoon.

This trail is relatively easy compared to the summit climb, making it ideal for those who want a less strenuous route but still crave dramatic scenery.

8. Silent Valley Reservoir to Slieve Bearnagh

Starting from Silent Valley Reservoir, this trail takes you along the edges of the water and into the hills. The reservoir itself is stunning, and walking alongside it gives a sense of tranquility that’s hard to find elsewhere. As the trail climbs, the water eventually disappears from view, replaced by rocky slopes and heather patches.

This hike offers a beautiful mix of water and mountain scenery. From my overall experience, it’s a perfect choice for photographers and anyone who appreciates the peaceful side of nature.

9. Slieve Bearnagh Southern Approach

The southern approach provides a more gradual ascent, making it perfect if you’re easing into mountain hiking. The trail winds through valleys dotted with wildflowers in spring and summer. You’ll see sheep grazing lazily and maybe even spot a red deer if you’re lucky.

Once you reach the top, you’ll have a unique perspective of the other trails below. This route combines accessibility with spectacular scenery, making it a must-see for first-time hikers in the area.

10. Hare’s Gap Trail

The Hare’s Gap Trail is one of the hidden gems of Slieve Bearnagh. It cuts through a narrow pass between peaks and offers dramatic views at every turn. The trail is moderately challenging, but the sense of seclusion makes it worthwhile. You’ll feel like you’ve discovered a secret part of the mountain that few visitors ever see.

This route is particularly stunning in late afternoon when the sun casts long shadows across the ridges, giving the landscape a golden glow.

11. Full Slieve Bearnagh Circuit

For the truly adventurous, the full circuit of Slieve Bearnagh is the ultimate challenge. This hike combines elements of the summit trail, ridge walk, and loop trail, giving you a comprehensive experience of the mountain. Expect a full day of walking, climbing, and breathtaking views.

Bring plenty of water, snacks, and your camera—this is a hike where every step is a photo opportunity. The full circuit gives you a sense of the mountain’s vastness and a deep appreciation for its natural beauty.

Tips for Hiking Slieve Bearnagh

No matter which route you choose, a few tips will make your experience safer and more enjoyable:
