Mourne Mountains

Sléibhte an Mhourne

A dramatic range of granite peaks in South Down offering outstanding hiking, with Slieve Donard being Northern Ireland's highest mountain and the source of the kingdom's best water. The mountains are characterized by distinctive stone walls and provide stunning views across the Irish Sea to the Isle of Man.

Things to do

• Climb Slieve Donard — Ascend Northern Ireland's highest peak at 850 metres via the popular Glen River Gorge or Donard Forest trail for panoramic views across the Irish Sea to the Isle of Man.
• Walk the Mourne Wall — Hike along the distinctive 22-mile granite dry-stone wall that encircles the mountains, built in the early 1900s to mark the water catchment area.
• Explore Slieve Commedagh — Trek this 764-metre peak offering challenging scrambling terrain and excellent vistas across the Mourne range and County Down countryside.
• Visit the Silent Valley Reservoir — Drive or walk to this scenic mountain lake with surrounding walking trails, visitor facilities, and the historic pumping station that supplies water to Belfast.
• Explore Bloody Bridge — Walk the accessible riverside trail through a dramatic gorge with waterfalls and pools, named after a 1641 massacre, situated on the mountain's eastern slope.
• Kayak or Fish the Mountain Rivers — Fish for brown trout in the pristine rivers that flow from the granite peaks, or paddle the quieter stretches popular with outdoor enthusiasts.

Food to try

• Fresh Mountain Trout — Locally caught and prepared trout from the Mourne rivers and reservoirs, typically served simply grilled or pan-fried in country restaurants and pubs.
• Mourne Seafood Chowder — A creamy soup combining locally sourced seafood from nearby Kilkeel harbour with local vegetables, warming visitors after mountain hikes.
• Soda Bread with Ulster Butter — Traditional Irish soda bread baked locally and served with creamy Ulster butter, a staple of farmhouse breakfasts and afternoon tea in the region.
• Boxty — A traditional potato pancake from the wider Ulster region served at local cafés, combining grated raw potato with flour and eaten with savoury or sweet fillings.
• Mourne Spring Water — Sample the pure mountain spring water that originates from the peaks and is bottled locally, famously used to supply Belfast's water supply since 1869.

Local customs & good to know

• Respect the Mourne Wall Heritage — The iconic dry-stone wall is a protected historical structure; stay on marked paths and do not damage or remove stones from this early 20th-century engineering feat.
• Mountain Safety is Essential — Weather changes rapidly in the Mournes; inform someone of your route, carry waterproofs, and check conditions before setting out as rescue services cover a vast area.
• Local Pub Culture — Visit traditional pubs in Kilkeel and Newcastle where locals gather; these spaces often feature live traditional Irish music on weekends and serve as community hubs.
• Early Closing Times Outside Summer — Many mountain-area facilities and attractions operate reduced hours from October to March; plan visits accordingly and book accommodation well in advance during peak season.
