This small village, just in the county of Powys, is at the southern foot of the Fforest Fawr area of the Brecon Beacons. The name, translated from Welsh, means 'floor of the valley of the Mellte', the Mellte being one of the rivers which have their sources in the hills above the village. It's a small village, but as this is an area of sparse population it would in the recent past have been quite an important local centre. It has a pub - The New Inn - and a 16th Century church, St Mary's. Ystradfellte is best known for the waterfalls and caves in the deep gorge cut by the Afon Mellte just to the south of the village.
