A-B. From the trailhead cross the road and follow the blue (and green and purple) arrows onto the sandy lane between the church and Doran’s pub. The green arrows are for the shorter Askamore Loop, the purple arrows are for the longer Slieveboy Loop. Continue along the sandy lane for more than 1km to a junction with a forestry road on your left. The loop proper begins here - you will return to this point from the opposite direction later - for now, turn left.
B-C. Continue to follow the blue (and green and purple) arrows along the forestry road for 3km - enjoying some fine views of the surrounding countryside as you go - before rejoining the sandy lane at what is known locally as the ‘hairpin’. The green loop veers right here - you veer left following the blue (and purple) arrows.
C-D. Follow the surfaced roadway downhill for 200m to a sharp left bend - and veer right onto a narrow forestry track. Continue to follow this track as it ascends over the next 500m to reach a 3-way junction where the purple loop turns left - but you continue straight ahead. After 300m you pass a junction where the purple loop rejoins from your left - continue straight and after 300m you exit forestry and rejoin the sandy lane you started out on. Turn left and downhill.
D-A. After only 200m you reach the junction at B above from where you began the loop. This time proceed straight ahead and enjoy the 1km back to the trailhead.
