Third highest summit in the Pumlumon range, Pen Pumlumon Llygad-bychan is perhaps most notable for its proximity to the source of the River Wye. To the north of the summit is the lovely pool of Llyn Llygad Rheidiol, while Pumlumon's principal summit is just a short walk along the Cambrian Way to the northeast. While the summit itself is not particularly distinguished and is known to be on the boggy side, it does offer lovely views across the Cambrian Mountains of Mid Wales.

The Wellington Monument is a stone column built on the summit of the south fort at Pen Dinas. A memorial to the Duke of Wellington, it was probably erected in 1858 or a year or two before. The main person responsible for seeing to its construction was W.E. Richards of Bryneithin. The monument takes the form of an eighteen metre high upended cannon. It is built of stone rubble and rises from a square podium, the shaft tapers before ariving at a swept out funnel. It is thought that the column was intended to carry at statue at the top, which was never installed. The monument serves to pinpoint the great later prehistoric hillfort crowning the hill. The monument was fully restored in 1999, following a lightning strike in 1997, with a replacement rounded slate surround at its top specially made at Blaenau Ffestiniog.
