Huge forest in the heart of Eryri (Snowdonia)...
Ceunant Cynfal National Nature Reserve, near Blaenau Ffestiniog
What's here
Welcome
Ceunant Cynfal is one of the finest gorges in Britain.
This narrow, deep gorge was created by the River Cynfal which descends from its source in central Eryri (Snowdonia) and becomes a raging torrent with steep cascades and waterfalls.
Rhaeadr Cynfal is one of the most dramatic of these waterfalls and you can view its tumbling waters from the restored Victorian viewing platform.
The oak woodland here is a remnant of a vast Celtic rainforest that once extended down the western side of Britain and Ireland.
Distinctive plant life thrives in the shady and humid conditions beneath the dense oak canopy and Ceunant Cynfal National Nature Reserve is a site of international importance.

What to see on the National Nature Reserve
Ceunant Cynfal is a National Nature Reserve.
National Nature Reserves are places with some of the very finest examples of wildlife habitats and geological features.
The landscape and wildlife varies depending on which time of year you visit – here’s what to look out for.
Geology
This is an ancient landscape – enormous flows of glacial meltwater at the end of the last Ice Age sculpted this gorge.
You can still see the tell-tale ‘hanging valleys’ (a valley cut across by a deeper valley or a cliff) and numerous geological features with names like ‘pot holes’, ‘slots’, ‘arches’ and a rock ‘stack’ – Huw Llwyd’s Pulpit.
Mosses, liverworts and lichens
The gorge boasts an impressive 154 different mosses and liverworts.
Several are scarce: look out for the uncommon bun moss, which forms cushions on the woodland floor and tree trunks.
Lichens are also abundant, including the rare disc granular lichen, which grows on the bark of mossy, mature oak trees.
Bats and birdlife
The woodland provides an ideal feeding ground for bats.
During evenings in summer and early autumn you may spot them feeding along the edge of the woods and in open glades.
The rare lesser horseshoe bat has its British stronghold here in North Wales, and it depends upon catching dung flies in the treetops courtesy of grazing animals within the woodlands.
The woodland sustains a healthy bird population, and notable summer visitors include redstart, wood warbler and pied flycatcher – the typical ‘upland oakwood’ species.

Meirionnydd Oakwoods
Ceunant Cynfal is one of six large Meirionnydd Oakwoods which are protected as National Nature Reserves.
These oakwoods are as globally important and as vulnerable as some tropical rainforests and are a remnant of a vast Atlantic ’wildwood’ that once extended down the western side of Britain and Ireland.
Two of the other Meirionnydd Oakwoods may be visited with care:
Dense vegetation and steep access mean that the other three Meirionnydd Oakwoods (Coed Camlyn, Coed Cymerau, and Coed y Rhygen) are not suitable for visitors.
Eryri (Snowdonia) National Park
Ceunant Cynfal is in Eryri (Snowdonia) National Park.
Eryri is the largest National Park in Wales and is home to picturesque towns and villages and the highest mountain in Wales.
It is looked after by the Eryri National Park Authority.
