Silent Valley Reservoir
Silent Valley Reservoir was built to trap water from the Mourne Mountains and is now the main water supply source for most of County Down and a large area of Belfast city. Surrounded by mountains, ‘The Valley’, located within the Mournes has beautiful parkland, lakes and a pond for visitors to explore.
There are new walking routes within Silent Valley each helping to demonstrate the history and heritage of the site, such as the Mourne Wall and the Binnian Tunnell. It is a steep climb to get to the dam wall though you are rewarded with magnificent views of the Mournes when you arrive.
