Its maybe hard to believe, but Northern Ireland was once short of water so someone decided to build a big storage place to gather all the rain that keeps falling on our heads for 364 days of the year (it seems) and they called it Silent Valley.
Silent Valley now supplies water for most of County Down and Belfast and it was built between 1923 & 1933 using a workforce of over 1000 men – 8 of whom died in the process. Its situated near Kilkeel and the water supply to fill the dam included diverting a river from Annalong which meant they had to tunnel a 3.62km hole through one of the Mourne mountains (Slieve Binnian) which was an amazing feat lit by using just candlelight.
Today, Silent Valley gets 50,000 visitors a year with most coming to experience the stunning views and make use of the many trails and walks around the area. The park has an information centre, a conference centre, and an education centre, all set inside some old bungalows (see below) and there’s a cafe there too. The famous Mourne Wall also cuts through the park which was constructed to mark out the catchment area for the Silent Valley dam. Its maybe not as good as the one in China but its still pretty impressive when you see it fade off into the distance.
After parking your car (its £4.50 entrance fee for a car full of people at time of posting) you walk along the path before arriving at the information centre above. Nothing too impressive yet.
Some information on the dam. Apparently the valley used to be called Happy Valley but its not certain why the name was changed (one idea about this is on the sign above). It really is incredibly quiet up there though. Spot the 2 crane flies. 🙂
Your first view of the dam. The water was below the overflow level on the day I visited which drains excess water off via the circular construction thing you can see on the right of the picture. I’m not sure where the water goes when it disappears down the hole (maybe its how the devil gets his shower water) but if you want to see it in action there’s a small video here: https://www.youtube.com/watch?v=MxUEfQd4mk4
The first picture is looking up the reservoir from the walkway embankment. Even on an overcast day like this its still pretty impressive. The second picture is looking across from the left hand side of the water.
A little bit of back story about the men who built the dam. They even had their own workers village called “Watertown” and you can still see some of the old foundations of Watertown next to this sign.
There are 5 walking routes around Silent Valley with one to suit every ability. I did the “Mountain Trail” (3.4km) route which is considered moderately difficult but it really wasn’t that bad. It gives good views over the reservoir from the left hand side of the water (as you come in). This picture was taken from near the top of the mountain trail.
As you descend from the Silent Valley mountain trail you’ll reach the Mourne Wall which usually becomes a feature of many of the Mourne mountain range walks given its meandering 22 miles of length. Its always stunning to see it disappear off into the distance.
And finally, a little plaque in memory of the 8 men who died in construction of the dam (and one at Ben Crom dam too).
