What are the main mountains in Ireland?
Ireland has several mountain ranges, though they are modest in height compared to continental ranges. The highest is the MacGillycuddy's Reeks in County Kerry, home to Carrauntoohil, the country's tallest peak at 1,038 meters. Other significant ranges include the Wicklow Mountains near Dublin and the Mourne Mountains.
What is Ireland's highest mountain range?
Short answer: The MacGillycuddy's Reeks in County Kerry is the highest mountain range in Ireland. It contains the only three peaks on the island that are over 1,000 meters tall.
Located in the beautiful Iveragh Peninsula, the MacGillycuddy's Reeks are a compact, rugged range of sandstone and siltstone peaks. They attract hikers and climbers from all over the world. While not high by international standards, their sharp ridges and unpredictable weather demand respect and proper preparation. The mountains are the centerpiece of a region known for its dramatic scenery, including the famous Ring of Kerry touring route.
Climbing Carrauntoohil: what you need to know
Carrauntoohil is Ireland's highest point, standing at 1,038 meters (3,406 feet). Climbing it is a serious undertaking that requires a good level of fitness and navigation skills. The most common route is via the Devil's Ladder, a steep gully filled with loose scree. This path can be dangerous in wet or icy conditions. Safer but longer alternatives like the Coomloughra Horseshoe route offer a full day of ridge walking for experienced mountaineers. You should always check the weather forecast before setting out. For any Irish mountain, a good rule of thumb is to prepare for four seasons in one day. Always pack waterproofs and a warm layer, even if it's sunny when you start.
Other peaks in the MacGillycuddy's Reeks
While Carrauntoohil gets most of the attention, the range includes Ireland's second and third highest peaks: Beenkeragh (1,010m) and Caher (1,001m). Connecting all three involves traversing the Beenkeragh Ridge, a narrow arête that requires scrambling and a head for heights. It's considered one of Ireland's classic ridge walks but is strictly for those with experience in mountain terrain. Many other smaller peaks in the range provide excellent hiking with fewer crowds.
Are there mountains near Dublin?
Short answer: Yes, the Wicklow Mountains are located immediately south of Dublin, making them an extremely accessible and popular destination for hiking and outdoor activities.
The Wicklow Mountains cover a large area of rounded granite peaks, rolling hills, and deep glacial valleys. Often called the "Garden of Ireland," the region is home to Wicklow Mountains National Park, which protects a significant portion of the landscape. Its proximity to the capital means you can leave the city and be on a mountain trail in under an hour. The landscape is a mix of open moorland, heather, and forestry plantations.
Popular trails in the Wicklow Mountains
You'll find trails for every ability here. The Great Sugar Loaf is a distinctive conical peak with a short, steep climb that rewards you with great views of the coast. Djouce Mountain offers a more substantial hike, often accessed from the scenic Sally Gap road. For long-distance walkers, the 131-kilometer Wicklow Way trail traverses the entire range from Dublin's suburbs down to County Carlow. You can find more details in our complete guide to the Wicklow Way.
The Spinc and Glendalough
Perhaps the most famous walk in Wicklow is the Spinc trail in Glendalough. This route climbs steeply out of a U-shaped valley via a series of wooden steps and a boardwalk along the cliff edge. The trail provides incredible views down onto the two lakes of Glendalough and its 6th-century monastic settlement. It's a moderately challenging loop walk that takes around 3-4 hours and is one of Ireland's most rewarding day hikes.
What are the most scenic mountain ranges?
Short answer: While beauty is subjective, the Mourne Mountains in County Down and the Twelve Bens in Connemara are consistently named among Ireland's most beautiful and dramatic ranges.
Ireland's mountains get their character from their relationship with the sea. Their moderate height is an advantage, as many peaks can be climbed in a day, offering views that stretch from green valleys right out to the wild Atlantic.
The Mourne Mountains in County Down
The Mourne Mountains are a compact cluster of 12 granite peaks rising steeply from the coast of County Down in Northern Ireland. Slieve Donard is the highest point at 850 meters. The range is famous for the Mourne Wall, a 22-mile dry-stone wall that crosses 15 of the summits. It was built between 1904 and 1922 to enclose a reservoir catchment area. The dramatic landscape is said to have inspired C.S. Lewis's vision of Narnia.
The Twelve Bens of Connemara
In the west of Ireland, the Twelve Bens (or Beanna Beola) are a group of sharp, conical peaks made of quartzite. This hard rock gives them a pale, almost silvery appearance that contrasts with the surrounding bogland and lakes of Connemara. A full traverse of the Bens is a very tough challenge for expert hikers, but many individual peaks, like Benbaun, offer stunning day hikes. Their jagged profile creates one of Ireland's most recognizable mountain skylines.
Are there any easy mountains to climb in Ireland?
Short answer: Yes, there are plenty of easy mountain climbs suitable for beginners, families, or those looking for a rewarding view without a full day's exertion.
Many popular Irish mountains have well-maintained paths, boardwalk sections, or stone steps that make them much more accessible. Here's what to do: pick a mountain inside a national park, as they typically have the best infrastructure and signage.
Torc Mountain, Killarney
At 535 meters, Torc Mountain is a fantastic option in Killarney National Park. Much of the trail follows a path of wooden sleepers, which helps protect the ground from erosion and makes the climb much easier. From the summit, you get a panoramic view over the Lakes of Killarney, the town, and the MacGillycuddy's Reeks. It's one of the best views in Ireland for a relatively short hike.
Diamond Hill, Connemara National Park
Diamond Hill (442m) is another excellent choice with a very well-constructed path. The trail is a loop that starts from the national park visitor center. The final ascent is steep with some stone steps, but the reward is an amazing 360-degree view of the Twelve Bens, the Connemara coastline, and the islands of Inishbofin and Inishturk. It's a perfect introduction to the unique beauty of the Connemara landscape.

Common mistakes when hiking in Ireland
- Underestimating the weather: People see a sunny start and don't pack for rain. Always bring waterproof gear and extra layers, as conditions in the mountains are very different from the valleys.
- Wearing the wrong shoes: Trainers or casual shoes are not suitable for wet and rocky terrain. You need waterproof hiking boots with good grip and ankle support to prevent slips and injuries.
- Relying only on a phone: Phone batteries can die, and signal is often non-existent. Carry a physical map and a compass, and know how to use them as a reliable backup for navigation.
- Starting too late: Hikers sometimes misjudge the time needed and get caught out after dark. Check the hike duration and sunset times, and give yourself plenty of buffer.
Alternatives to mountain climbing
- Coastal walks: For spectacular scenery without the elevation, try a coastal path. The Cliffs of Moher Coastal Walk or the Howth Head Cliff Path near Dublin are excellent choices.
- Forest parks: On days with low cloud or heavy rain, forest parks like Gougane Barra in Cork or Donadea in Kildare offer sheltered walks among beautiful trees.
- Island loops: Walking around one of Ireland's offshore islands provides a unique perspective. The Aran Islands or Clare Island offer marked loop walks with great sea views.
- The Burren Way: This trail in County Clare offers a completely different experience, taking you through a unique glacial-karst limestone landscape with rare flora.
Quick recap
- Ireland's highest mountain range is the MacGillycuddy's Reeks in County Kerry.
- The Wicklow Mountains provide very accessible hiking just south of Dublin.
- The Mournes and the Twelve Bens are famous for their dramatic, scenic beauty.
