Coed Llangwyfan woodland clings onto a steep-sided hill that opens out to heather covered slopes.
The car park is the gateway to two impressive hillforts – Penycloddiau and Moel Arthur.
There are public footpaths to both hillforts and the views from the top on a clear day are hard to beat.
The circular waymarked walking trail follows a sheltered level path from the car park through the woodland to a viewpoint.
The walking trail is waymarked and starts from the Coed Llangwyfan car park.
Gradually drop down on a hillside path through huge conifer trees with filtered views across the valley.
Enjoy the viewpoint at the halfway point with wide views across the Vale of Clwyd.
Return on a lower level path through broadleaved woodland back up to the car park.
There are several public footpaths from the Coed Llangwyfan car park.

These routes may not be waymarked and we recommend that you take a map with you.
