The Wicklow Way begins at the car park adjacent to Marlay House, with its courtyard of interesting craft workshops and a pleasant little coffee shop. The trail wanders through the delightful sylvan surroundings of this fine suburban public park, before tunnelling under the M50 motorway to begin the walk's first ascent southwards towards the Dublin hills and the first of several forest vistas (this one predominantly of communication masts!).
Passing Kilmashogue, Fairy Castle (536m), Two Rock and Tibradden mountains the trail descends to reach the Glencullen road at Ballybrack after 9 km. Walking eastwards along the road, the route then turns south (A diversion of 2km eastwards will take the weak-willed to Johnny Fox's world-famous pub and also an occasional bus service back to the city!) to cross the Glencullen River. The hike then begins the ascent towards Prince William's Seat (555m) followed by a zigzag descent to the Enniskerry road at about 17km, directly north of Knockree Hill.
There are three options for accommodation close to the trail at Knockree. Those wishing to explore a little off-trail can visit the picturesque village of Enniskerry, which is 4km to the east. Visitor attractions here include Powerscourt House and Gardens.
