The Grey Mare's Tail Waterfall

OS Grid ref:- SH7861

Grey Mares Tail WaterfallThe dramatic Grey Mare's Tail Waterfall, known in Welsh by the seldom used name of Rhaeadr y Parc Mawr, is situated in a beautiful wooded glade at Coed Felin Blwm, the Lead Mill Wood, near to the market town of Llanrwst.

The waterfall is situated on the eastern edge of the dense and extensive Gwydir Forest, which covers 7,250 ha and was established in 1921 by the Forestry Commision. The fall is fed by a wide stream which has its source in the forest and flows on to join the River Conway further down. The waterfall actually consists of two falls, which drop into a plunge pool beneath.

The remains of disused mill buildings may be seen near the waterfall. Felin Blwm lead mill was originally built by the wealthy and influential Wynn family of nearby Gwydir Castle to crush ore from Parc Mine in the Gwydir Forest

The area around the falls now serves as a Nature Reserve and is owned by the Forestry Commision. There is a very pleasant walk from Llanrwst to the waterfall which takes in the village of Llanrychwyn, the characterful village church, which dates to the eleventh century, is reputed to be the oldest in Wales, the church has no electricity and is known locally as Llewelyn's Church in honour of Llywelyn ap Iorwerth, otherwise known as Llywelyn the Great. Prince Llywelyn owned a hunting lodge at nearby Trefriw, and along with his wife Joan, who was the illegitimate daughter of King John of England, would often climb the steep slope up to Llanrhychwyn church.
