The woodland provides an excellent habitat for wildlife – look out for birds such as buzzards, goldcrests and coal tits.
The small lake known as Llyn Ochin has dried up but this marshy area now attracts dragonflies and newts, and plants like cotton grass thrive here.
The trail may be used by walkers, cyclists and horse riders and it is waymarked so that walkers follow the route in a different direction to cyclists and horse riders.
The walking trail is waymarked from start to finish.
Look out for the information panel at the start of the trail.
Find out about walking trail grades.
The walking trail sets off on a wide track through the iron gates at the woodland entrance and then turns left onto a path through the woodland.
Look out for ruined buildings from a 19th century lead mine, the remains of a shepherd’s cottage with a walled meadow full of wildflowers in summer and a newly replanted orchard.
At the end of the trail there is an optional climb to a trig point from where you can enjoy views of the Jubilee Tower at the top of Moel Famau and the Dee Estuary.
