Rhinog Fawr

Dwyfor Meirionnydd is a constituency of the Senedd, first created for the former Assembly's 2007 election. It elects one Member of the Senedd by the first past the post method of election. Also, however, it is one of eight constituencies in the Mid and West Wales electoral region, which elects four additional members, in addition to nine constituency members, to produce a degree of proportional representation for the region as a whole.

Dwyfor Meirionnydd is a constituency of the House of Commons of the Parliament of the United Kingdom (at Westminster). The seat was created by the Welsh Boundary Commission for the 2010 general election, and replaced the old north Wales seat of Meirionnydd Nant Conwy. Dwyfor Meirionnydd is bordered to the north by Arfon and Aberconwy. The same boundaries were used for the Dwyfor Meirionnydd Welsh Assembly constituency in the 2007 Welsh Assembly election. Like its predecessors, it is a Plaid Cymru stronghold, with their candidate in 2019 achieving a majority of 15.9%. The constituency is to retain its name and gain wards, as part of the 2023 Periodic Review of Westminster constituencies and under the June 2023 final recommendations of the Boundary Commission for Wales for the next United Kingdom general election.

Rhinog Fach is a mountain in Snowdonia, North Wales and forms part of the Rhinogydd. Technically, Rhinog Fach is a subsidiary summit of Y Llethr, but is a Marilyn. To the north lies its higher cousin Rhinog Fawr, separated by the shapely pass of Bwlch Drws Ardudwy. Although shorter than the highest mountain in the Rhinog range, Y Llethr, it is often regarded as the true 'king of the Rhinogydd' due to its spectacular rocky peak. Unlike Fach, Y Llethr's peak is grassy and unremarkable.

The Rhinogydd (a Welsh plural form, often anglicised as Rhinogs and also known by the alternative Welsh plural Rhinogau) are a range of mountains located east of Harlech in North Wales. The name Rhinogydd derives from the names of two of the more famous peaks, Rhinog Fawr and Rhinog Fach, although the greatest elevation in the range is reached by Y Llethr, 756 m (2,480 feet). Foel Penolau, the northernmost summit of the range, was promoted to a Hewitt in 2018 due to a new survey. The Rhinogydd are notably rocky and heather-clad towards the northern end of the range, especially around Rhinog Fawr, Rhinog Fach and towards Moel Ysgyfarnogod. The southern end, around Y Llethr, Diffwys and the Ysgethin Valley has a softer, grassy character. A population of feral goats are in the range. Over 30 km² are protected as a Special Area of Conservation and a National Nature Reserve.

Y Llethr is the highest mountain in the Rhinogydd range of Snowdonia, in north Wales. The summit consists of a flat grassy top marked only by a small cairn. The summit is more in keeping with its southern flanks than its rugged northern approach. The shortest route to the summit goes from the valley of Cwm Nantcol in the west, either directly or via Bwlch Drws Ardudwy and over the mountain of Rhinog Fach. To the south lies the mountain of Diffwys, to the south-east lies the mountain of Y Garn, to the north lies Rhinog Fach and to the west lies the hill of Moelfre.

Crib-y-rhiw is a top of Y Llethr and a ridge in the Rhinogydd of Snowdonia, north Wales. The summit straddles a thin ridge connecting Y Llethr to Diffwys.

Cwm Nantcol is a valley in the Ardudwy area of the county of Gwynedd in Wales. It lies in the Rhinogydd range of mountains in Snowdonia and carries the Afon Cwmnantcol. At the head of Cwn Nantcol is the Bwlch Drws Ardudwy pass, from where it is possible to negotiate the summits of Rhinog Fawr and Rhinog Fach.

Llyn Cwm Bychan is a lake in north Wales, and is one of the sources of the River Artro which flows south westwards through Llanbedr and onwards to the sea. It is located in the Rhinogydd mountains of Snowdonia.

The River Artro (Welsh: Afon Artro) is a river in Gwynedd, Wales. It is about 4.5 miles (7.2 km) long and has its source at Llyn Cwm Bychan below Rhinog Fawr and Moel Ysgyfarnogod. It flows westwards from its source and is joined by the Afon Cwmnantcol at Pentre Gwynfryn before passing through the centre of Llanbedr where it turns north and passes Pensarn Wharf. The Artro enters the sea at a sizeable tidal estuary between Llandanwg and Mochras/Shell Island. The current estuary was formed following a diversion of the Artro by the Earl of Winchilsea in 1819 to improve access to the wharf at Pensarn which was the shipment point for slate from Llanfair and Llanbedr. Prior to this the Artro entered the sea to the south of Mochras.

Moel Ysgyfarnogod (Welsh for 'Bare hill of the hares') is a mountain in Snowdonia, North Wales and is the northernmost of the Rhinogydd. Rhinog Fawr lies directly south.It overlooks Llyn Trawsfynydd, and from the summit it is possible to see the towns of Porthmadog and Blaenau Ffestiniog. It may be climbed from Trawsfynydd in the east, or from Talsarnau in the west. To the north-west of the summit, on an area of moorland and rocky outcrops, lies Bryn Cader Faner, an ancient stone circle. It is one of the finest examples of a Bronze Age cairn in Britain, and has rocky standing stones along its circumference.

Ardudwy (Welsh pronunciation: [arˈdɨ̞duːɨ̯]) is an area of Gwynedd in north-west Wales, lying between Tremadog Bay and the Rhinogydd. Administratively, under the old Kingdom of Gwynedd, it was first a division of the sub kingdom (cantref) of Dunoding and later a commote in its own right. The fertile swathe of land stretching from Barmouth to Harlech was historically used as pasture. The name exists in the modern community and village of Dyffryn Ardudwy.

Moelfre is a hill in Wales on the far western edge of the Snowdonia National Park, 3 miles (4.8 km) from the village of Dyffryn Ardudwy, 5 miles (8.0 km) from the village of Llanbedr and about 10 miles (16 km) from the town of Harlech. It forms part of the Rhinogydd range. Moelfre reaches a height of 589 metres (1,932 ft). Moelfre is a prominent peak that separates Cwm Nantcol from Ysgethin Valley. Moelfre is also known for a legend of three women who worked on the sabbath and were turned into standing stones.
