Source of the River Blackwater

The River Blackwater, Ireland’s second longest river after the Shannon, rises in Knockanefune Mountain in County Kerry, in the area known as Sliabh Luachra, near the Cork/Kerry border. It flows for 104 miles in an easterly direction through Counties Kerry, Cork and Waterford where it turns abruptly south at Cappoquin and flows into the sea at Youghal, County Cork.

The “B” shows the location of the start of the walk to the source of the river.

The Latitude and Longitude of the walk start are: 52.20605879, -9.28824804. If you use the useful Loc8 system on your SatNav the code is: QZ3-89-FF7.

This is a closer look at the location:

Again, “B” is the start of the walk. You proceed in a northerly direction, following the blue waymarked signs, until you arrive at the source (circled). It takes about 45 minutes. It is possible to drive the route but be careful of potholes. Really though, you should walk it. At the source you have a choice of going back the way you came (which is what I did) or continuing the looped walk which takes about 2 hours 30 minutes to complete.  There are two looped walks here – one is waymarked in green, the other in blue; blue is the one you need to follow.

It’s hard to believe that such a small flow of water will become a mighty river.

The start of the Blackwater Valley. The source is at the top of the path and even though the river is not visible here it can be heard flowing through the reeds on the right.

The first bridge – near Doctor’s Hill, a few kilometres downstream.

And so the River Blackwater continues on its journey until it reaches the open sea at Youghal.
