Wicklow Mountains National Park
Lough Ouler

Lough Ouler

Lough Ouler sits on the northeast flank of Tonelagee Mountain at an altitude of 570 metres. Where the lake sits now was once the source of a glacier during the Ice Age. The glacier gradually gouged out through erosion a bowl shaped chunk of the mountain (known as a corrie). After the ice melted away, water gathered at the base of the corrie forming Lough Ouler. Looking down at the lake from the top of Tonelagee Mountain the Lake is distinctly heart shaped. There is no waymarked trail to the Lake and to get there you must be properly equipped for hillwalking. The main access points are the Wicklow Gap and Glenmacnass Waterfall carparks.
