Pen yr Allt Uchaf

Gwaun y Llwyni is a subsidiary summit of Aran Fawddwy in southern Snowdonia, Wales. It forms a part of the Aran mountain range. The peak's southern face is very steep and forms one of the backwalls of Cwm Cywarch. The summit is grassy and is marked by a small cairn. Pen yr Allt Uchaf rises on the other side of Cwm Cywarch, Aran Fawddwy is to the north-east, Waun Camddwr to the north and Glasgwm to the west.

Waun Camddwr is a top of Aran Fawddwy in the south of the Snowdonia National Park in Gwynedd, Wales. It is the highest point on a wide boggy area between the summits of Aran Fawddwy and Glasgwm. It was surveyed after the first Nuttall list was compiled, and found to have just enough prominence to be included. The summit is a rocky outcrop amid an area of heather, long grass and peat bog. Gwaun y Llwyni rises to the south of the summit.

The Afon Cerist is a small river that flows from underneath Craig Portas, the cliffs on the north side of Maesglase mountain, to meet the River Dyfi at Dinas Mawddwy. It forms the northern border of the Dyfi Hills.

Craig Cywarch is an extensive crag looming above Cwm Cywarch. The nearest village is Dinas Mawddwy on the A470. Climbing routes on the various buttresses range from E2 to V Diff. Access paths can be rather overgrown and even finding the bottom of the routes can be rather difficult.

Dinas Mawddwy (Welsh pronunciation: [ˈdiːnas mau̯ðʊɨ̯]; ) is a town in the community of Mawddwy in south-east Gwynedd, north Wales. It lies within the Snowdonia National Park, but just to the east of the main A470, and consequently many visitors pass the town by. Its population is roughly 600. The town marks the junction of the unclassified road to Llanuwchllyn which climbs up through the mountains to cross Bwlch y Groes at its highest point, the second highest road pass in Wales. This minor road also provides the closest access to the mountain Aran Fawddwy and is the nearest settlement to Craig Cywarch.

Mawddwy is a community in the county of Gwynedd, Wales, and is 88.3 miles (142.2 km) from Cardiff and 172.8 miles (278.0 km) from London. In 2011 the population of Mawddwy was 622 with 59.5% of them able to speak Welsh. It is one of the largest and most sparsely populated communities in Wales.

Pont Minllyn (also known as Pont-y-Ffinant or Pontrusk Bridge) is a bridge spanning the Afon Dyfi, north of the village of Mallwyd, in Gwynedd, Wales. It was built by John Davies, rector of Mallwyd between 1603 and 1644 and a famed Welsh scholar who wrote a Welsh grammar and worked on early Welsh translations of the Bible and the Book of Common Prayer. Pont Minllyn was designed as a packhorse bridge to facilitate the transportation of goods. It is a Grade II listed building and a Scheduled monument.

The Meirion Mill Railway was a narrow gauge railway that operated at Meirion Mill in Dinas Mawddwy, Wales. It only operated for three years from 1975 to 1977.

Foel Dinas is a mountain in Wales. It is the north-westernmost peak of the Dyfi Hills and sits above the town of Dinas Mawddwy. In the 1870s its eastern and northern slopes were planted with trees by Sir Edmund Buckley, the lord of the manor of Mawddwy. On the northern flank is Llyn Foel Dinas, a lake which was dammed to form a reservoir, providing the water supply to Buckley's manor house in Dinas Mawddwy. The southern shoulder of the mountain was the location of Minllyn quarry from the 1790s to 1925.
