Pincyn Llys is in Clocaenog Forest, a huge area of woodland, open moorland and rivers.
This small roadside car park is the starting point for a short walk to the Pincyn Llys monument.
The monument is the highest point in Clocaenog Forest and there are views across the Vale of Clwyd.
Lord Bagot erected the 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 and it was then replanted by the Forestry Commission in the 1930s.
The starts from the information panel on the other side of the road to the parking area.
The walking trail is waymarked from start to finish.
Find out about walking trail grades.
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.
The Hiraethog Trail goes through Pincyn Llys.
This trail links the villages of Pentrefoelas, Cerrigydrudion, Llanfihangel Glyn Myfr and Llanrhaeadr via public footpaths and quiet lanes across some of Denbighshire and Conwy’s most beautiful and remote countryside.
It may not be waymarked and we recommend that you take a map with you.
For more information go to the Denbighshire Countryside Service website.
Clocaenog is a huge conifer forest which is the size of 10,000 rugby pitches (100km2).
It lies at the southern end of Hiraethog Moor and was first planted in the 1930s by the Forestry Commission.
Although still a working forest, it is now a place for people to enjoy and home for a wide variety of wildlife.
Red squirrels live in Clocaenog Forest but you will be very lucky to see one as they move over large areas and are quite secretive.
Rare black grouse, known for their flamboyant courtship display, known as ‘lekking’, live on the forest edge.
In addition to Pincyn Llys, waymarked trails start from several other Natural Resources Wales car parks in Clocaenog Forest:

It will form a connected ecological network running throughout Wales, bringing social, economic and environmental benefits.
Parts of the network will eventually form a trail running the length and breadth of Wales, so anyone can access it wherever they live.
