Nantygwryd
Dyffryn Mymbyr is a valley in Snowdonia, in north-west Wales, approximately 5 miles (8.0 km) in length, and leading up from Capel Curig to the Pen-y-Gwryd hotel.
The river Nantygwryd, originally called Y Mymbyr in Llywelyn the Great's charter of 1198, starts at Llyn Cwm-y-ffynnon, high above the Pen-y-Gwryd hotel, and flows into Llynnau Mymbyr going towards Capel Curig. The valley, like the river, lies both in Gwynedd and Conwy county borough.
Today there are at least two active, hill rearing, sheep farms; Garth, featured in the 1967 BBC Wales documentary "Shepherds of Moel Siabod", and Cwm Farm.
The area commands excellent views of the Snowdon horseshoe, which (viewed left to right) takes in the peaks of Y Lliwedd, Yr Wyddfa (Snowdon), Crib Goch and Crib y Ddysgl.
The valley is the location of the Capel Curig weather station, which on many occasions has recorded the wettest weather in Wales [1].
Dyffryn Mymbyr is also the location of 'Dyffryn', the farm in Thomas Firbank's best-selling autobiographical novel (first published in 1940) entitled "I bought a mountain". In the book he describes life in Dyffryn Mymbyr after he bought the 2,400-acre (9.7 km2) farm in 1931 when he was just 21. The farm included the southern slopes of the Glyders, and neither Firbank nor his wife, Esme, whom he married in 1934, had any previous experience of farming. However, they succeeded in winning the respect of their employees and neighbours, and slowly built up a healthy stock of 3000 sheep. The couple later divorced, and Esme (as Esme Kirby: see her obituary) and her husband Peter Kirby went on to be founder members of the Snowdonia Society, the farm acting as home to the society before it moved to Ty Hyll ("The Ugly House"). The location of Dyffryn Mymbyr, the farm, dates back to 1350, and the current property is now owned by the National Trust. The farmhouse and cottage are now available to rent from the National Trust as holiday cottages, the money raised from their rental helps the National Trust with conservation work.
