Ruin beside Trinant Trinant is a stream flowing in the groove passing the ruined stone feature - perhaps a sheepfold but rather small. The ruin isn't marked on OS maps at any scale but can be discerned clearly on Google Earth. Llechwedd-llyfn is the mountain dome on the skyline.

Summit area of Arenig Fach The summit of Arenig Fach has minor rock exposures, a cairn and a trig point - stone built and bearing a flush bracket numbered S8547; curiously just below the FB number, a coin (1p) has been glued! The view distantly is towards the mountains of Snowdonia.

Walls below Clogwyn Du These walls are reached as access land ends below the roughness of Clogwyn Du which is a minor feature on the eastern side of the mountain Arenig Fach. The reservoir beyond is Llyn Celyn and the hill rising above it is Mynydd Nodol.

The start of a re-forestation? This one small and lonely rowan tree is finding a purchase in the peat of the moor below Arenig Fach. The sheep population on the hills here is notably sparse, and a few such trees can be found in places.

A small woodland beginning These scattered rowans and spruces are finding a living on the moors of Cefn Côch below Arenig Fach, maybe the start of more extensive woods to come.

County boundary stone and fenceline The stone is on a line marking the boundary between the historic Merionydd and Denbighshire counties, whilst the fence conveniently follows that boundary, but just keeps two sets of sheep apart.

Along the old county boundary The line of the historic boundary between Merionydd and Denbighshire, which runs across these remote moors. These historic boundaries, marked through this moor by a series of stones, were pretty much abandoned as a result of the 1972 Local Government Act, which took effect a couple of years later. The fence is a more modern convenience which coincidentally runs along the same line, presumably delineating the lands of two neighbouring hillfarms.

The upper part of Arenig Fach Toiling up a steep part of the little Arenig, using the fence as a guide to the summit. The deep heather and grass moorland of the Migneint persists practically to the top.

That's the hard work done... A fence corner at the top of the steep pull up from Cefn Côch. At long last, the deep heather moorland give way to shorter vegetation too.

OS Flush Bracket - Arenig Fach summit Flush Bracket S8547 in the trig of Arenig Fach. It's not clear why there once was a new penny-piece glued onto the bracket below the serial number - photos show it there between 2006 & March or April 2008, but it's long gone now.
