Pincyn Llys is a small roadside car park which is the starting point for a short walk to the highest point in Clocaenog Forest.
The walk takes you to the Pincyn Llys monument from where there are views across the Vale of Clwyd.
Lord Bagot erected this monument in 1830 to commemorate the planting of a conifer forest.
The forest was cut down during the First World War to provide wooden props for the trenches and coal mines.
It was replanted by the Forestry Commission in the 1930s.
The trail is waymarked and starts from the information panel on the other side of the road to the parking area.
The walk starts in shady woodland and makes its way to open moorland before the short but steep climb to the Pincyn Llys monument.
The full inscriptions on the monument are worth a read.
The monument stands at the highest point in Clocaenog Forest (1358ft/414m) and there is also an ancient earthwork and trig point with views across the Vale of Clwyd.
The walk returns to the car park along the same path.
