Tonelagee

Tonelagee rises to 815.8 meters, making it the third highest peak in the Wicklow Mountains, with granite-rich bedrock and steep terrain throughout its slopes.

In 1895, naturalist H.C. Hart documented Tonelagee's distinctive features, including the crater-like valley and cliffs that overlook the waters of Lough Ouler.

The mountain's name originates from Irish 'Tóin le Gaoith', translating to 'backside to the wind', reflecting traditional naming practices based on geographical characteristics.

Hikers access the summit through multiple routes, including paths from Glenmacnass Car Park and Wicklow Gap, with winter conditions requiring additional preparation.

Below the summit lies Lough Ouler, a natural heart-shaped lake that forms a distinct geographical feature visible from the mountain's higher elevations.
