Maen Madog also called Maen Madoc is a standing stone in the heart of the Brecon Beacons National Park, about one mile north of Ystradfellte. It stands immediately beside the old Roman road known as Sarn Helen, just outside the Blaen Llia forestry plantation. A mile to the north is Maen Llia, a Bronze Age standing stone. The stone is not in its original location, and no grave has been found. Historians theorise that the burial remains were destroyed by the extremely acid soil. When Maen Madoc was recorded in 1805 it was recumbent. It was re-erected at some point in the 19th century and again in 1940. It is believed to have been erected in the late Roman period, possibly to mark the site of an early Christian burial. The southwest edge of the stone is inscribed with very worn Latin text reading 'DERVAC(IVS) FILIVS IVSTI (H)IC IACIT'. This translates loosely as 'Dervacus, Son of Justus lies here'. One theory says that Maen Madoc was a pre-existing Bronze Age standing stone that was simply re-used to mark a late-Roman burial site.

Sgwd yr Eira is the most impressive waterfall in the Pontneddfechan area. It is a high, broad, and powerful waterfall that resembles a curtain of water when it is in full flow. The fact that you can walk behind it just adds to the beauty of this amphitheatre you find yourself in. To get there, however, you have to take around 170 steps that go down the steep side of the valley to the river bed. If this worries you somewhat, just take your time when you go down and when you come back up. In addition, at the bottom, the path that goes to the waterfall is rocky and slippery, and if you walk behind the waterfall, it will be a bit wet, so a waterproof might be necessary.

As well as the caves, here you have Porth yr Ogof car park, or Cwm Porth car park, to give it its proper name. It's one of the better car parks, with toilets and a small shop. On most days there is also hot food and drinks available. The famous Four Waterfalls walk also starts from here. This is a spectacular walk, and each waterfall is great in its own way. They are Sgwd Clun-Gwyn, Sgwd Isaf Clun-Gwyn, Sgwd y Pannwr, and Sgwd yr Eira.

The Four Waterfalls Walk is my idea of heaven. Hidden away in a quiet corner of the Brecon Beacons, there is a famous waterfall trail that takes in four great waterfalls, it is located near the quaint village of Ystradfellte. The trail has stunning scenery, and the main access to it is from the car park at Porth yr Ogof, or the Cwm Porth car park, to give it its proper name. The Four Waterfalls are all spectacular in their own different ways, and they are Sgwd Clun-Gwyn, Sgwd Isaf Clun-Gwyn, Sgwd y Pannwr, and Sgwd yr Eira.

Sgwd Isaf Clun-Gwyn is one of the most photographed falls on the four waterfalls walk. Thus, it is known as the “Lower” Fall of the White Meadow in English because it is on the same river and you have to head downhill to get to it. It is a great place for gorge walking, and I have had a lot of fun here over the years. It's a gorgeous place to come and visit in waterfall country.

This footbridge across the Afon Mellte is located just north of Sgwd Clun Gwyn. The bridge is located on the connector trail leading from Porth Yr Ogof car park to the Four Falls Trail. This is a nice, easy, and very popular walk.
