The loop is situated in the Rathgormack area of Co. Waterford. The scenery is dominated by the Comeragh mountain range with a great mix of features that includes the long and precipitous Knockanaffrin Ridge, the shadowy depths and glacial amphitheatre of Coumshingaun, the magnificent plateau and falls in Coum Mahon. Tourism to the area is becoming more popular and Rathgormack now has a Hiking Centre which can accommodate 20 people.
A-B. Starting from the car park area turn right on the surfaced road and follow the green arrow for 100m to reach Glenpatrick Bridge over the Glasha River. Immediately after the bridge, turn left into forestry - pass through the barrier and veer left at the Y-junction. Continue along the forestry road as it ascends alongside the river and after nearly 1km, veer left at the next Y-junction. After 500m the forestry road approaches an exit onto the R678 near Boola Bridge. Do not exit - instead swing sharp right, staying on forestry road.
B-C. Continue to ascend - turning left at the next junction and, shortly afterwards, left again. Now you are travelling parallel to (but well above) the R678 - continue to do so for almost 1km to reach a marker post which directs you left and onto a sandy track into forestry. This short track exits onto the surfaced road - take care crossing it to join an old Coach/Drover Road which starts your homeward journey.
C-D. Continue to follow the green arrows along the old road - with wonderful views of the Comeragh Mountains opening in front of you. After more than 1km the road begins the descent towards Glenpatrick. The last section of the old road changes to a tarred surface before you join the R678. Turn left here.
D-A. Follow the R678 for 200m to reach a laneway on your right. Turn right and enjoy this magical tree-lined laneway as it descends to reach a surfaced road at the ruins of a Slate Mine. Turn left - the trailhead is only 50m away.
