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.

Mallwyd () is a small village at the most southern end of Gwynedd, Wales, in the Mawddwy community, in the valley of the River Dyfi. It lies on the A470 approximately halfway between Dolgellau and Machynlleth, and forms the junction of the A458 towards Welshpool. The nearest villages are Dinas Mawddwy, two miles to the north, and Aberangell a similar distance to the south. The River Dugoed flows into the River Dyfi near the village. The Cambrian Way long-distance walk passes through the village.

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.

Moel y Ffridd (also known as Foel y Ffridd) is a mountain in Wales. It lies north-west of the village of Aberangell and west of Mallwyd and is one of the Dyfi Hills.

Aberangell railway station was an intermediate railway station on the Mawddwy Railway which ran from Cemmaes Road to Dinas Mawddy in the Welsh county of Merionethshire. The station was opened by the Mawddwy Railway in 1867 and closed to all goods traffic in 1908. The railway re-opened in 1911 with all services run by the Cambrian Railways. It was amalgamated into the Great Western Railway in 1923 as part of the grouping of British railways, and remained open to passenger and freight traffic until 1931 and 1952, respectively. The station was the transshipment point between the branch and the Hendre Ddu Tramway.
