More about Coed Felenrhyd & Llennyrch

Coed Felenrhyd & Llennyrch is a 310ha (765 acre) property in the Snowdonia National Park. Stretching from Llyn Trawsfynydd in the east almost to the confluence of the Prysor and tidal Dwyryd rivers in the west, it is one of the Trust's largest woods in Wales.

To the north, the wood is bounded by the steep gorge of the Afon Prysor, an atmospheric place of pools and steep waterfalls such as Rhaeadr Ddu, a popular landmark. To the south, the rugged uplands of the Rhinog mountains provide a stunning backdrop and a walk around Llennyrch farm offers views north across the Moelwynion, Nantlle ridge and Snowdon (Yr Wyddfa) itself.

Coed Felenrhyd has the rare distinction of being mentioned by name (Melenrhyd, Y Felen Rhyd) in the famous collection of Welsh legends, the Mabinogion, as the last resting place of Pryderi, King of Dyfed, killed in single combat with Gwydion the trickster. These tales were written down in the 12th century, but recorded in an oral tradition that is much older.

But the natural history of Coed Felenrhyd & Llennyrch goes back much further: this is a wood that has been many thousands of years in the making. And that long history is reflected in the sheer diversity of the living things that make it their home.

The wood is one of Europe’s best remaining examples of Atlantic oak woodland. It’s a habitat that has been dubbed the Celtic Rainforest and it is as important globally - and as vulnerable – as some tropical rainforests.

Its oak, ash and hazel canopy echoes with the song of redstart and wood warbler, while rare lichens, mosses and liverworts thrive, covering every surface along streams and rocky gullies. Otters hunt along the river and rare lesser horseshoe bats flit among the tree branches on summer nights.

Of course, it is still a living landscape. The hefted flock are cared for by a tenant farmer and in summer visitors may also encounter Welsh black cattle in the fields, heathland and mires. As well as woodland, visitors can explore grasslands which in autumn are rich in colourful waxcap fungi and extensive areas of heathland, bog and mire, where reptiles bask in the summer sun.
With an extensive network of footpaths, Coed Felenrhyd & Llennyrch is a marvellous place to get close to nature – and to get in touch with a timeless jewel. It retains a sense of real remoteness and you can easily spend a whole day exploring its heritage, both human and natural.


Set above the broad Vale of Ffestiniog, Coed Felenrhyd & Llennyrch is an important element of the vale’s beautiful oakwood landscape.  The fast-flowing Afon Prysor, with its many cascades and pools, runs through the wood and visitors are drawn both by awe-inspiring waterfalls and stunning mountain views.

Access and walks

At present there is one waymarked trail within Coed Felenrhyd, which starts from the westernmost entrance near the Maentwrog hydro power station. An information panel near this entrance illustrates the paths within Coed Felenrhyd. The waymarked loop follows Llwybr Gwyndaf upstream along the steep gorge of the Prysor. Wide and level at first, it later becomes steeper as it rises towards Rhaeadr Du, the Black Falls, from where is climbs a long flight of steps before looping back through the upper woodland, past a house called Cae'n y Coed which occupies a clearing in the wood, before following the public footpath back down to the main entrance.

Dolen Melenrhyd. 3.8km/2.4 miles. Strenuous. Allow 2-3 hours.

Follow in the footsteps of the heroes of the Mabinogion and explore the heart of this magical Celtic rainforest. The wood's majestic waterfalls and delicate filmy ferns are magical at any time of year.

Most paths are narrow with an earth surface that can be muddy when wet. Some long flights of steps with steep and occasionally exposed sections. Rough and rocky or rooty in places.

A Coastal Communities route also climbs through the wood from Maentwrog on a sunken bridleway.

Approaching from the east, Llennyrch can be reached by parking at the visitor centre at Llyn Trawsfynydd and following the new cycle trail across the dam: there is a public footpath just beyond the dam which follows river downstream from the lake, crossing a stream and climbing to Llennyrch farmhouse (NB this can be very wet, especially in winter). From here, a footpath links the farm southward to the tarmac road near Llyn Llennyrch, or westward toward Coed Felenrhyd, where the path cross a stile and links to a good path to the right which follows the boundary between the farm and Coed Felenrhyd for a time before linking into the path network within Coed Felenrhyd. The other main old trackways within the wood at Llennyrch will also be maintained as permissive paths for visitors to explore. It is possible to use these paths to link in to Felenrhyd's waymarked route just above Rhaeadr Ddu.

A linear walk from Trawsfynydd to Maentwrog through Llennyrch and Coed Felenrhyd would also make a great day out.
