More information

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.

Visitor information

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 also 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.
