December 30, 2024, Pen-Pych Waterfall

Resembling something which should be found in Iceland, Pen Pych waterfall is a series of cascades which tumble over a sheer sided sedimentary rock face. The base of waterfall is enveloped by a half amphitheatre cliffs which only adds to the waterfalls impressive appearance. Theres is no plunge pool at the base of the falls, instead the tallest section spills 21m onto number of boulders which have tumbled from the cliffs above in years gone by. The path will lead you to a large rocky viewing area to the right hand side of the falls beneath the cliffs. You can climb up to the base of the falls, if you do do that take care as the rocks can be very slippery. (https://ohwhataknight.co.uk/blog/pen-pych-mountain-and-waterfall-hike-guide)

A beautiful waterfall often overlooked by the masses as they head for more famous waterfalls in the Brecon Beacons. But you know better! Be aware that in places the footpath is narrow, uneven and very steep. You will need to take extra care in the wet / after prolonged rain.
