Silent Valley

The Silent Valley Reservoir was built to gather water from the Mourne Mountains and is the main water supply source for most of County Down and a large part of Belfast.

Ringed by mountains, ‘The Valley’, located within the Mourne Area of Outstanding Natural Beauty, has become an important visitor attraction in Northern Ireland. It attracts around 50,000 visitors per year most of whom come to enjoy the peace and solitude of this mountain area with its unique landscapes and varied wildlife.

Northern Ireland Water has provided a number of visitor facilities at the valley including a restaurant, information centre, conference centre and education centre – all housed in two old colonial style bungalows and enjoying delightful views over the parkland.

NI Water would like to remind visitors they are entering a site that has vegetation and fungi natural to the area that could be poisonous if eaten.   Please ensure pets and children are properly supervised at all times. 


The reservoir grounds are open daily from 10:00 until 18:30 (Summer) and 10:00 until 16:00 (October to March).
