Mourne Mountains, County Down

Northern Ireland is home to the beautiful Mourne Mountains and Ring of Gullion, located in the Mourne Gullion Strangford Geopark, it offers a stunning range of Mountain peaks. The famous Slieve Donard is Northern Irelands highest mountain peak towering above the seaside town of Newcastle, County Down. There are 6 peaks over 700 metres high, with Donard the highest at 850m. The area is recognised as an area of outstanding natural beauty and it is not hard to see why, with an immense amount of granite peaks squeezed into an area only 15 miles by 8 miles giving magnificent views. 

Stretching 22 miles over the Mournes is the historical Mourne Wall, this interesting staple piece is made up of natural granite stone,  standing 1.5m high and 0.8m thick.  It was constructed by the Belfast Water Commissioners to prevent livestock from contaminating the reservoirs. The Mourne wall passes over fifteen of the mountain areas, you can't ever miss it!  

Rivers, forests, lakes, and reservoirs make up some of the area and there are amazing scenic spots and viewpoints to visit scattered throughout the alluring Mourne Mountains. 

In the last century, dams have been built to provide the main water supply to Northern Ireland's capital city, Belfast.  Silent Valley, located in the Mournes, is a great parkland for hikers and families with lots of walking trails which are easy to access.  You will be treated to spectacular views. For a fun experience, when leaving Silent Valley turn right and take an excursion to Spegla Dam, park on the Electric Brae, otherwise known as the “Magic Hill”, let your parking brake off and experience the "magic" of your car rolling up hill, how strange!
