The Slieve Aughty mountains lie within south-east Galway and north-east Clare.
The highest peak is Maghera in County Clare (400m).
Many of the peaks within the Aughty range are under 300m and could therefore be thought of as hills rather than mountains.
Most of the Aughty are underlain by Devonian Old Red Sandstone (Figure 2) but outliers of Lower Paleozoic rocks provide occasional outcrops capping the peaks.
Carboniferous limestone underlies the surrounding lowlands and foothills of the Aughty Mountains.
Covering c.250 square miles this mountain range is vast but virtually unknown outside the region.
This mountain range consists of two ridges divided by the Owendalulleegh River, which flows west into Lough Cutra near Gort in Galway. Several other rivers rise in the Aughty range.
