About Knocknagun

Sitting on the high plateau between the Dublin and Wicklow border, this unassuming Tump offers a wild, peat-covered landscape. Often traversed alongside neighbouring Prince William’s Seat, its broad summit provides a clear perspective of the telecommunications mast on Kippure and the urban sprawl of Dublin meeting the Irish Sea.

Did You Know?

  • The name originates from the Irish 'Cnoc na nGunna', which translates to 'Hill of the Guns', likely referring to historical military activity or sporting rights in the area.
  • The hill marks a point on the border between County Dublin and County Wicklow, part of the granite-based Leinster Chain that defines the local geology.
  • From the summit, you have an excellent vantage point of the 'golf ball' radar dome on Kippure to the southwest, and the distinctive profile of the Great Sugar Loaf to the southeast.
  • It is frequently bagged as part of a circuit starting from Glencullen, often combined with the nearby Glendoo Mountain and Prince William's Seat.
  • The summit plateau is notorious for its deep blanket bog; it is a place where your choice of footwear is frequently and ruthlessly interrogated by the terrain.
