Prince William's Seat is described as a popular hill walking location for families given its ease of access and proximity to Dublin City. A recommended route is the 10.5-kilometre 3-4 hour loop route that starts from a forest car-park at the Boranaraltry Bridge in Glencullen, rises up to the summit of Knocknagon through the Glencullen Forest, and then crosses to the summit of Prince William's Seat, before returning to the bridge.
