Is how I used to pronounce this! Pistyll Rhaeadr.
It's been at least 6 pictures since the last waterfall, must be due for another one. Been mining the archives again and found this shot of the lower part of the Pistyll Rhaeadr, a beautiful waterfall that is counted as one of the '7 wonders of Wales'. The falls are in three stages, the top one being the longest, the second goes through a natural arch, and then this final stage - a total of 240 feet or 73 metres. The river is known as the Afon Disgynfa above the falls and the Afon Rhaeadr below it for some reason. Students of the Welsh language will confirm Pistyll Rhaeadr translates to 'Spring of the Waterfall' in English. The falls are to be found at the end of a long single track road from the village of Llanrhaeadr-ym-Mochnant, in the Berwyn mountains.
