- Distance: approximately 20–21 km
- Estimated walking time: around 7 hours

The route begins beside Marlay House in Marlay Park before passing through wooded parkland and crossing beneath the M50 motorway. The trail then climbs steadily towards the Dublin Mountains through forestry on the slopes of Kilmashogue Mountain.
Higher sections pass near Two Rock Mountain and Fairy Castle, with extensive views across Dublin Bay, the city and the surrounding uplands. The terrain becomes more exposed across open mountain sections with heath and blanket bog landscapes.
After descending towards the Glencullen area, the route continues southwards through forest and mountain terrain near Prince William's Seat before entering County Wicklow. The final section descends towards Glencree and Knockree through woodland and quieter upland scenery.
