Great waterfall and worth the trip, however it is not traversable by MTB down to it, lock your bike to the trees at the top. Also the path at the top of the waterfall this app shows also isnt a path at all, it literally ends and it took over an hour to carry and push the bikes up to the fire road through bogs, logs, heather and mountain grass.... so you need to double back and save yourself the pain!

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)

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.

Wow! Tarren y Bwllfa looms large over the valley below. It is one of Britain's most Southerly glacial cwms. Stunning views of the Brecon Beacons and the former industrial landscape nearby.

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.

We walked miles. Up to the waterfall on Gillies trail, followed the path up onto the rocky and then to the trig point on Twyn Brynbychan, above the cynnon valleys. Enjoyed a breather on top, before trekking around the back forestry where you can see Aberfan and Merthyr Vale and headed over to the bronze age sight before descending down to Cwmaman and back to the car.

The Rocking Stone or "Y Maen Chwyf" in Welsh is a glacial boulder remaining from the Ice Age. It formed the central point for a "Gorsedd" or "Gathering of Bards" in 1814, which was organised by stonemason, Edward Williams, known as "Iolo Morganwg". The Gorsedd Circle of smaller stones was constructed in 1849 by Evan Davies, Bardic name "Myfyr Morganwg" and has often been used for Bardic gatherings, and as a focal point for other public occasions.
