Garn Wen (SN 845 459) |
As I travelled south the
early morning chill and clear skies foretold a good day on the hill. I planned on doing two small walks near to
Llanwrtyd, however as I neared the smallest town in Britain a large grey cloud
bank emerged over the western part of the Elenydd. This quickly pushed east and by the time I’d
parked in the yard of Ty’n-y-maes farm there were spots of rain falling.
I’d been on one of the
two hills I planned on visiting during my first walk once before, in July 2000,
and did on that day what I hoped to do today, get permission to park at the
farm and approach the hills from the south-west on a good track that leads up
beside the Nant y Cae.
As I drove into the farm
yard Tyssul Davies was already busy at work, once I’d introduced myself and mentioned
my previous visit we chatted for ten minutes about the names of the hills and
the route up to their summits. By now
the rain was falling so I thanked Tyssul and wondered if I should sit out the
wet weather. Not wanting to linger I
grabbed my brolly and set off up the track.
The gravelled track soon
became a green lane and pushed its way up the cwm, my brolly was up and
sheltered me, my rucksack and my camera gear, an umbrella can be a great
addition to hill walking kit for the lower hills. Ahead the sky was deep grey and did not look
inviting.
The green track to the hills with the deep uninviting grey cloud ahead |
I left the green track
before its end and jumped over the narrow stream and clambered over a fence and
followed a vehicle track on the moor as it gained height adjacent to a
contouring fence. In time this led
through an open gate on to the upper part of Garn Wen.
I remember this hill
being rather wild from my previous visit and it didn’t disappoint today, the
whole summit area is one of tussock grass, heather and bog, all leading up to
its ancient cairn that has been re-fashioned into a wind shelter with its trig
pillar sitting inside. As I gained
height the large ancient cairn came into view across the moor, between me and
it was an unsavoury bog which proved fun to cross.
The ancient cairn at the summit of Garn Wen |
Once at the summit I
considered placing the Trimble just to the south-west of the cairn and trig,
but I then examined inside the wind shelter and found stable ground within it
which was higher than the ground just to the south-west. This high ground could of course be made of
rocks from the ancient cairn but I did not want to excavate something from
antiquity so I placed the Trimble on top of my rucksack, positioned three rocks
at its base, which I re-positioned afterwards, to stabilise it and once the
accuracy level was attained I pressed ‘Log’.
Gathering data at the summit of Garn Wen |
As I waited for the five
minutes of data to be collected the first burst of sunshine shone out of a
brightening sky. Packing the equipment
away I followed a vehicle track down toward the bog which proved an easier
crossing that my alternative ascent route.
I then roughly re-traced my route back down to the fence and the narrow
stream.
Following the vehicle track on the moor toward the second hill of the day |
I had no immediate
intention of gathering data from the connecting bwlch to Pen Twyn as the map
indicated that it was immersed in a conifer plantation, but there was a gap
between a small section of mature trees and a larger section of saplings, so I
thought I’d investigate. I stumbled my
way down to this land from the open hillside, found a tree stump and positioned
my rucksack on it with the Trimble placed on top and gathered another five
minutes of data.
Gathering data at the bwlch of Pen Twyn |
By now the deep grey
cloud had been swept away and sunshine pre-dominated as I followed the fence
beside the large conifer plantation toward the summit of Pen Twyn. This is the hill that Anton Ciritis completed
the Pedwarau on, on 9th September 2014. The summit area has a neat cairn positioned
on it and I placed the Trimble on top of my rucksack approximately 1 metre from
it on what I judged to be the highest part of the hill.
Gathering data at the summit of Pen Twyn |
Once the allotted five minutes
of data were gathered I packed the equipment away and descended the southerly
part of the hill, this proved steep in places and gave views south toward the
shapely profile of a 396m map heighted hill which is listed as a Sub-Pedwar
with c 113m of drop.
All in a line |

The southerly profile of Pen Twyn |
This southerly route
down the hill led to a vehicle track over a field which then accessed a gate
and the track back to Ty’n-y-maes. As I
arrived in the farm yard Tyssul was in conversation with three people, I
stopped and chatted and showed him on the map where the next two hills on my
planned second walk were situated, and he kindly suggested what farm I should
park at.
