| Foel Ddu (SH 697 095) |
Having recently LIDARed
this area I thought I had better visit, and with the weather set fine I headed
to the upper Dyffryn Dysynni, a beautiful part of the country and one that I
had not visited for a number of years.

On my surveying agenda were two great lumps of hills; Foel Cae’rberllan and Foel Ddu, they are not great in height but are relatively prominent, placed on the western ridge of the latter is Mynydd Ty’n y Fach; a recent deletion from 400m Sub-Pedwarau and a hill whose sudden lack of status could be confirmed by the Trimble.
My first hill of the day
was Castell y Bere, I had not previously visited but had wanted to for a long
time. The castle was constructed in the
1220’s by Llywelyn the Great, and as with similar constructions it proceeded to
have a turbulent history, and after being besieged in 1294 it fell in to
disrepair.
The connecting bwlch for
the castle is located in an adjacent field and as the Trimble gathered its
allotted data I stood and looked out on the profile of Craig yr Aderyn and its
satellite peaks, they rose greened in early summer freshness, rounded and
appealing they would lead me toward them in a few days’ time.

The remains of the castle are an atmospheric place, dominated by near hills it is almost hidden from view by the growth of trees on its lower slopes, and yet it is a place of history, and one that thankfully has not had the misfortune to accumulate a gift shop and kiosk, it sits and stares and stands against the passage of time.

When in the castle ruins the ever changing play of light accentuated atmosphere with near hillsides casting light then shade, adding depth and perspective to the landscape. Surveying its high point was periphery, but once done I retraced my inward steps to the entrance gate and proceeded on my way.

A green track leads up the steep westerly slopes of Foel Cae’rberllan and as the morning’s warmth was now creeping across the land, this proved a welcome addition compared to the slight chill earlier in the day, and in time the green track led me to the small grassed and rocky knoll that makes up the summit of this hill.

Across the intervening Nant yr Eira valley, Foel Ddu rose in a wild looking way, with its upper slopes festooned in tussock grass, between me and it was a steep descent down slopes of bluebells until the grazing fields below were reached.

My next surveying objective was the connecting bwlch which is placed beside a stone wall; due to prospective satellite disruption I found placing the Trimble atop my rucksack on top of the wall to be the most convenient way to gather data. This involved a balancing act, but once the offset to the ground below was measured I sat beneath the wall and Trimble and spent a few minutes looking at the beauty of a caterpillar in the undergrowth as it sunned itself.

Another green track led up the lower south-western flank of Foel Ddu and eased passage toward the tussock laden upper part of the hill. I was soon on top sitting in clumps of bilberry grass as the Trimble gathered data. The sun shone and although a cooling breeze blew it felt good to be out on the hill, and there were few places where I would have rather been.

Slightly easier passage on the northern side of the fence that follows the western ridge of Foel Ddu led toward the connecting bwlch, and once this was Trimbled I headed for the summit.
As the Trimble gathered
data at the summit of Mynydd Ty’n y Fach I looked out to the wild surrounds of
the Nant Pencoed, a great expanse of tussock and heather laden bog, it sat
quietly tranquil, probably seldom visited except by a farmer.

Only one hill remained to visit and survey; Craig Ysgiog, the outlier of Foel Ddu, and this gave stunning views down the flat bedded expanse of Dyffryn Dysynni past the rounded profile of Craig yr Aderyn to the coast beyond.

By now the cloud that had built and then thinned had disappeared and the hills were bathed in late afternoon glow, giving a beautiful colour to the land. I followed an old path down the hill, only diverting from it when confronted by a grazing heard of Welsh Blacks who looked inquisitively toward me.

The path led toward the country lane which would lead me back to my car at Llanfihangel-y-Pennant, it had been a good time on the hill with a lazied feel to the late afternoon amongst quiet surrounds in the beautiful upper part of the Dysynni valley.
