Walking time: 3 hrs
Start in Marlay Park and follow the Wicklow Way markers (or make your own way) to the top carpark.
Leaving the park, turn right and follow the line of the M50 to the roundabout and go left under the motorway. Take the first exit from the next roundabout onto Kilmashogue Lane and walk up the steep hill to Kilmashogue Wood. With the carpark on your left, take the left hand path and climb up through the trees beside Stackstown Golf Course.
When you get past the golf course, the view on your left hand side opens out to let you see across the city to the bay.
If the weather is bad, you have the option to continue on this path through the trees across to Three Rock. This alternative is marked in blue on the map.
But the better, and more challenging option, is the take the right turn for the Wicklow Way. This option is shown in orange on the map. Follow the Wicklow Way until it meets the Dublin Way, then turn left and climb up until you reach the Fairy Fort. If you are lucky and the weather is clear, the views up here are fantastic.
At the Fairy Fort, go left across to Three Rock. The two route options shown on the map merge here. Follow the Dublin Way trail to the right. Watch out here for mountain bikers emerging from the trails on the right. As you go along the forestry road, watch out for the route marker on your left. This will bring you through the woods to another forestry road. Be careful here, there are a few crossing points for mountain bikes.
Go right here, and follow the track onto the old golf course – now closed. Veer right and follow the path down to the Glencullen Rd. Turn left and you will be at the crossroads and pub in Glencullen.
There are infrequent 44B buses back down to Dundrum Luas station - on weekdays only. Or walk through the crossroads and follow the road down to Kiltiernan where you can catch the more frequent 44.
