Start at the Upper Lake car park at Glendalough. Follow the white-arrow Spinc route up the wooden steps and along the boardwalk above the Upper Lake. At the southern end of the boardwalk, take the red-arrow Wicklow Way trail south over Mullacor. The descent into Glenmalure is steep and rough underfoot in places. The trail meets the valley road near the Glenmalure Lodge. Allow 5.5 hours at a steady pace. Linear walk — arrange transport from Glenmalure back to Glendalough.
A beautifully restored historic guesthouse on the Square in Tinahely — the Wicklow Way passes through the village. Double, twin and small-double rooms, all with private bathrooms. Self-service coded entry — arrive when it suits you.
