Llyn Dinas

Llyn Dinas is a lake near Beddgelert, Gwynedd in north Wales. It is formed by the River Glaslyn. Llyn Dinas lies on the valley floor a few miles north of Beddgelert at an altitude of about 55 metres above sea level. It has an area of 60 acres (240,000 m2) and is fairly shallow, with the maximum depth only 10 metres. The lake offers good fishing for salmon and trout. It takes its name from the nearby Dinas Emrys, a rocky and wooded hill just downstream of the lake where the remains of both medieval and older fortifications have been found. A rock near the lake named Carreg yr Eryr (The stone of the eagle) was said in a charter of 1198 to mark the spot where the boundaries of the three cantrefs of Aberconwy, Ardudwy and Arfon met. According to Giraldus Cambrensis an eagle used to perch on it once a week, anticipating battle between the men of the three cantrefs.

A498 road
A498 road

The A498 is a 16-mile road between Pen-y-Gwryd and Porthmadog in North Wales. At Pen-y-Gwryd, the A4086 Llanberis Pass route bears off to the north. The A498 descends from a 277 m (909 ft.) summit at Pen-y-Gwryd and runs south west through the village of Beddgelert and the Aberglaslyn Pass, where it overlaps the A4085. The A498 then passes through Tremadog, overlapping the A487 for a short length before passing under the Cambrian Coast railway and terminating at Penamser on the A497 (52.9336°N 4.1543°W / 52.9336; -4.1543 (A498 road (southern end))), about a mile west of Porthmadog. At its northern end, the road forms a link via the A4086 with the A5 at Capel Curig, forming a useful holiday route to the Beddgelert/Porthmadog area. At the junctions, the A4086 to Llanberis is the minor road at Pen-y-Gwryd, while the A498 is the minor road at Beddgelert. At Pont Aberglaslyn, the A4085 is the minor road diverging to Penrhyndeudraeth and at Tremadog, the A498 is the major road. The junction west of Tremadog is a roundabout and at Penamser, the A498 is the minor road. There is a steep descent of Nantgwynant and some 1+3⁄4 miles of this is on a substandard, narrow twisting alignment, where larger vehicles have difficulty in passing. There are further substandard sections in the Aberglaslyn Pass and towards Tremadog and coaches have had difficulty passing in this section. The road passes through Beddgelert by way of a sharp right angled bend over a river bridge, not recommended for articulated vehicles. In the Aberglaslyn Pass the trackbed of the Welsh Highland Railway, now being reconstructed, can be seen on the opposite side of the Afon Glaslyn. At its west end, the route crosses the new A487 Porthmadog Bypass at a roundabout west of Tremadog.

Yr Arddu (South)
Yr Arddu (South)

Yr Arddu is a large hill in Snowdonia, Wales (Not to be confused with the 589 metre Yr Arddu (North) to the east of Snowdon). It lies approximately 2.5 km south east of the village of Beddgelert and just over 1 km from the rather more famous mountain Cnicht. It is a rugged hill with widespread rock outcrops and cliffs. A small lake, Llyn yr Arddu, is located on the flanks of the mountain. The recognised summit is at 388m to the South of the hill, but the highest point, named Cerrig-y-Myllt on only the most detailed UK Ordnance Survey mapping, is at 463m above the two small lakes to the North of the hill. The craggy nature of the hill is due to the presence of lavas and tuffs (volcanic ash deposits) dating from the Ordovician period when Snowdonia was characterised by numerous volcanic eruptions; Yr Arddu is a particularly good location to see the record of Ordovician volcanism. The Yr Arddu Tuffs may be the earliest eruptive phase of the Lower Rhyolitic Tuff Formation.The whole hill is a site of special scientific interest designated by the Countryside Council for Wales.Yr Arddu is commonly approached by a footpath leaving the minor road that links Nantmor to Nant Gwynant running along the valley of Blaen Nanmor, but the final 0.5 km has no paths marked on UK Ordnance Survey mapping. However, a marked path runs South East from Nantmor Mountain Centre at Gelli-Iago. From this an intermittent rough path runs from West of Clogwyn Coch up to the two small lakes. The hill can also be approached with more difficulty from its West flank up to the small lake Llyn yr Arddu.
