Carn Liath is one of our favourite mountains in Highland Perthshire. It’s a 975m Munro and is one of the three peaks that make up the Beinn a’Ghlo range. Although not the highest in the range, Carn Liath is the most prominent and can be clearly seen from the A9 (see Blair Castle shot below).
The walk in starts from a car park near Loch Moraig and can be a bit boggy, crossing a stream several times. The hill itself is a pretty steep climb up on a well worn path, but on a clear day the view from the top is well worth the effort.
The other two peaks can be picked off on the same trip but this vastly extends the walk.
