Sally Gap
R115Sally Gap to Glendalough
A lonely bog road over the Wicklow Mountains.
The R115 'Old Military Road' crosses Sally Gap at over 500 m through the wild blanket bog of the Wicklow Mountains, past Glenmacnass waterfall. Empty, atmospheric and exposed; watch for sheep, sudden mist, and unfenced bog right up to the tarmac.
