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)

Loose, steep trail down to the pools but well worth the effort. Good footwear is a must if you want to climb down into the gorge. Silica mine needs a decent torch, phone light will not cut through the dark when you get further in!

Moel Penderyn 371m ⛰️ Moel Penderyn is on the edge of Penderyn village, located in the Brecon Beacons National Park county borough of Rhondda Cynon Taff, South Wales. It also appeared to be named as 'Y Foel Penderyn' on older maps. With a summit elevation of only 371m in height, Moel Penderyn is marked by a bright, vivid, beautiful Dragonised trig point!!❤️👌

High above the A470 to the north of Quaker’s Yard, the Giant’s Bite is a dramatic gap in the skyline quarried from the ridge top at the former Cefn Glas mine and quarry. ❤️👌 The site was intensively grazed up to the mid-1990s when a large belt of native trees were planted on the lower slopes. These trees are now maturing and have helped to heal the visible mining scares. The shales forming the upper soil horizons support a wide variety of native flowering grassland species including wild strawberry, cowslip, foxglove and wild thyme, and the site is increasingly becoming re-vegetated by scrub species. Incredibly Fine views of the Taff and Cynon valleys are afforded from the summit ridge, while the line of the former Glamorganshire Canal is also discernible.
