Starting from the car park, enter the forestry following the green arrows. You will also see blue arrows, which are for the longer ‘Source of Blackwater’ loop. After almost 1km you will reach a junction with a forest road to the right. Proceed straight on here. Continue to follow the forestry road for a further 1km, after which you will reach a 3-way junction. Turn right here, leaving behind the blue loop as it proceeds uphill towards Knockanefune and the source of the Blackwater River. Now you begin your homeward journey, following forestry roads as they zig-zag their way to a 3-way junction near Doctor’s Hill. Here, you turn right. With Doctor’s Hill on your left, continue along the forestry road to the junction you passed at the start of the walk. Here, you turn left and walk back to the trailhead and your starting point.
