1. Slieve Bearnagh Summit Trail
The classic summit route is the one most hikers think of when they imagine conquering Slieve Bearnagh. Starting from the Ben Crom Reservoir, this trail climbs steadily through heather-covered slopes and rocky ridges. Along the way, you’ll pass small streams and scattered boulders that make for excellent photo stops.
The trail is moderately difficult, requiring a good level of fitness, but the views from the top are unmatched. Looking over the Mourne Mountains and down into the surrounding valleys, you’ll see why this hike is a must for any outdoor enthusiast. From my overall experience, the best time to tackle this route is early morning when the mist is lifting—it adds a mystical quality to the peaks.
2. The Mourne Wall Walk
For hikers who love history as much as scenery, the Mourne Wall walk offers the perfect combination. This 35-kilometer trek stretches across the Mourne Mountains, including Slieve Bearnagh, and follows the iconic Mourne Wall, a dry-stone wall built to enclose the Silent Valley Reservoir.
You can tackle the walk in sections or take on the entire route. Either way, the sense of accomplishment you get from reaching points like Slieve Bearnagh’s summit while tracing this historic boundary is unforgettable. Along the way, expect to see a mix of boggy terrain, rocky ridges, and sweeping vistas. It’s challenging but incredibly rewarding.
3. Slieve Bearnagh Circular Route
If you’re not a fan of retracing your steps, the circular route around Slieve Bearnagh is ideal. Starting near the Glen River, this path loops around the mountain, giving you multiple angles of the summit and the surrounding peaks.
The terrain varies from steep ascents to gentle grassy slopes, and you’ll find yourself crossing streams and small wooden bridges that add a touch of charm to the hike. From my own personal experience, this route is fantastic in late summer when the wildflowers are in full bloom. You’ll find yourself stopping every few minutes just to admire the colors.
4. Bearnagh to Slieve Commedagh Ridge
For those looking for a longer day out, the ridge walk connecting Slieve Bearnagh to Slieve Commedagh is an unforgettable adventure. This hike follows the high ridges of the Mournes, giving uninterrupted views of the surrounding mountains and valleys.
Expect challenging climbs, narrow ridges, and occasional rock scrambles, but the reward is spectacular. Reaching the summit of Slieve Commedagh and looking back at Bearnagh makes every step worth it. You truly get a sense of the scale and beauty of the Mournes here.
5. The Waterfall Route
If waterfalls make your heart skip a beat, the Waterfall Route to Slieve Bearnagh is for you. Starting from the Annalong Valley, this path winds through lush forested areas, past cascading waterfalls, before opening up onto the rocky slopes of the mountain.
The combination of forest, water, and mountain makes this a varied and visually stunning hike. From my overall experience, carrying a camera or even a smartphone with good battery life is essential—every turn offers a photo opportunity you’ll want to capture.
6. Silent Valley to Slieve Bearnagh
This route is one of the most atmospheric in the Mournes, taking you from the Silent Valley Reservoir straight up to Slieve Bearnagh. The path begins on well-trodden gravel paths along the reservoir, gradually giving way to rugged mountain trails.
Along the way, you’ll pass moss-covered rocks and occasional patches of wild heather. This hike is moderately challenging but extremely rewarding, especially when you reach the summit and can look back over the tranquil reservoir below. It’s a route that feels remote yet accessible, a rare combination in any hiking destination.
7. Slieve Bearnagh via The Chimney
If adventure is your middle name, the Chimney route is for you. This is not your casual stroll—this path includes a narrow, steep rock formation that requires careful climbing and a touch of courage. The reward? One of the most dramatic viewpoints in the Mournes.
From my own personal experience, the sense of achievement after navigating the Chimney cannot be overstated. The panorama from the top stretches for miles, and it feels as though you’re on top of the world. It’s a route that mixes adrenaline with natural beauty, a combination you rarely find.

For a gentler approach, the Glen River Path offers a scenic, manageable ascent. This route follows the river through the valley before gradually climbing the slopes of Slieve Bearnagh.
Along the way, you’ll see an array of flora and fauna, from wildflowers to mountain birds. This is one of the most peaceful routes, perfect for those who want to combine a hike with moments of quiet reflection. From my overall experience, stopping by the river for a short break adds a refreshing pause in your journey.
9. The Heather Trail
Late summer is the perfect time for the Heather Trail, a route that winds through thick purple heather blankets before reaching the higher slopes of Slieve Bearnagh.
The colors are mesmerizing, and the scent of heather in the air makes the hike sensory in ways other trails can’t match. While it’s a moderate hike, the visual rewards at the summit make it feel effortless. You’ll truly fall in love with the Mournes when taking this trail.
10. Slieve Bearnagh Sunset Route
For hikers who want to combine exercise with one of nature’s greatest shows, the Sunset Route is unbeatable. Starting in the late afternoon, this path takes you along the eastern slopes so you reach the summit as the sun sets behind the mountains.
The sky transforms with hues of orange, pink, and purple, reflecting across the valleys below. From my own personal experience, timing is everything on this hike. Arriving just as the sun dips below the horizon creates a memory that stays with you long after the trail is behind you.
