Visiting our sites safely
We are working hard to provide a safe and welcoming experience as our sites re-open.
Please take personal responsibility for your safety, making additional preparations ahead of your visit and abiding by the safety measures in place.
We have changed the normal route for some of our trails to help you maintain social distancing – please follow signs on site.
Coed Nercwys may look like an ordinary woodland but if you follow the waymarked trail you will discover some heritage features tucked away amongst the trees.
The panels along the trail tell the stories of the woodland’s rich history and the people who once lived and worked here.
The woodland also 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.
A slate plaque near the car park entrance commemorates the Millennium Oak Trees that were planted here by the local community.
The walking trail and the mountain bike trail follow a similar route but they are waymarked so that walkers and cyclists follow the route in different directions.
The walking trail is waymarked and starts from the Coed Nercwys car park.
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.
All our mountain bike trails are waymarked and have been graded for difficulty.
At the start of the trail there is an information panel – please read this before setting off.
This cycle trail is a great place for families to safely enjoy cycling away from busy roads, and at the same time learn about the woodland’s varied history.
The wide track from the iron gates at the woodland entrance meanders through the forest, avoiding major climbs and offering spectacular views over the Cheshire Plain and beyond.
There are several public footpaths from the Coed Nercwys car park.
See the information panel in the car park for a suggested route to Bryn Alyn, the second largest limestone pavement in Wales (moderate, 4 miles/6.3 kilometres).
This route may not be waymarked and we recommend that you take a map with you.
