Cwm Carn Forest, near Newport

Caerphilly County Borough Council

What's here

The Y Mynydd Downhill trail has had some essential maintenance works carried out and many features have been reshaped. Please take extra care until you get used to the changes on this trail.


Set in the heart of the South Wales valleys, Cwm Carn Forest is easy to reach from the M4 and is home to a forest drive, mountain bike trails and walking routes.

The Forestry Commission started to plant trees in the hills around Cwmcarn village in the 1920s.

This former mining area is now a popular destination for visitors especially the forest drive which re-opened in 2021 after extensive redevelopment.

Cwm Carn Forest Drive


Cwm Carn Forest Drive has been a popular visitor attraction for many years.

The forest drive was closed in November 2014 to allow 150,000 diseased larch trees to be felled and removed from the forest.

After the last trees were felled in November 2019 a project to re-develop the forest drive got underway.

Following significant investment and redevelopment by Natural Resources Wales the forest drive re-opened in June 2021.

The seven-mile-long drive has eight stop-off points with a range of newly-developed visitor facilities including play areas, accessible footpaths, sensory tunnels and a wooden sculpture trail.

There are picnic areas, BBQ facilities and toilets in some of the stop-off points.

Caerphilly County Borough Council runs the forest drive through a partnership agreement with Natural Resources Wales.

For information about visiting Cwm Carn Forest Drive see the Cwm Carn Forest website.
