Many of the trees in Cwmcarn Forest have been infected by larch disease (Phytophthora ramorum). The forest drive through Cwmcarn Forest has been closed to allow the felling to take place safely. There may also be diversions and closures to footpaths and mountain bike trails. See below for the latest information.


The Forestry Commission started to plant trees in Cwmcarn in 1922. Since then, the hills of this previously mined area have been transformed into peaceful forests with impressive views.

With two cross country mountain bike trails and two downhill mountain bike trails, Cwmcarn is a popular destination for mountain bikers. There is an onsite uplift provider for the downhill trails and a pump track.

There are also walking trails and a fishing lake and, if you want to stay longer, the riverside camp site welcomes caravans and tents (book via Cwmcarn Visitor Centre). There are also six timber framed camping pods for hire.

Cwmcarn Forest Visitor Centre

The Cwmcarn Forest Visitor Centre, run by Caerphilly County Borough Council, has a spacious information area where you will find walking guides, maps and information on the surrounding area.

There is a great selection of gifts in the gift shop featuring locally produced crafts and Welsh goods.

The café offers a wide range of snacks and cakes and has an outdoor seating area which stretches around the centre and overlooks the Nantcarn River.

The Pedalhounds downhill course opened in 2014. It follows the line of the old “club track” down a steep sided valley in the forest.
