The reservoirs

Silent Valley reservoir

Drive into the centre of the Mourne Mountains and park at the Silent Valley Reservoir, then walk up to the high lakes and Ben Crom. The Silent Valley is a mountain park surrounded by the Mourne peaks, Slieve Binnian, Slievenaglough and Ben Crom. The reservoir was built to gather water from the Mourne Mountains, and the Silent Valley and Ben Crom reservoirs supply water for most of County Down and a large part of Belfast

The Mournes were chosen for their natural supply of pure water, which is a result of high rainfall in the area. This area is also free from pollution and industry. The area is capable of providing 30 million gallons of water per day.

Silent Valley, Mourne Mountains

The two reservoirs are ringed by mountains and the reservoir grounds contain parkland, lakes and ponds which were the natural landscape of the valley floor. You can enjoy the mountain scenery, woodland walks and an exhibition centre and cafe where you can learn the story of the building of the dam in 1933. The information centre and cafe are in two old colonial style houses close to a large car park.

The Mourne Wall

The Mourne Wall marks the extent of the water catchment area and was finished in 1922 having taken 18yrs to build. It stands up to 8ft high, is on average 3ft wide and is 22miles long connecting the summits of 12 mountains. The wall was built of natural granite using traditional dry stone walling techniques.
