The forest experience in the heart of the valleys with trails for walkers and proficient mountain bikers
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.
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.
Many of the trees in Cwmcarn Forest have been infected by larch disease (Phytophthora ramorum). These infected trees are being cut down and removed.
All of the walking trails are waymarked and start from the visitor centre.
