Snowdonia, or Eryri, is a mountainous region and national park in North Wales. It contains all 15 mountains in Wales over 3000 feet high, including the country's highest, Snowdon, which is 1,085 metres (3,560 ft) tall. These peaks are all part of the Snowdon, Glyderau, and Carneddau ranges in the north of the region. The shorter Moelwynion and Moel Hebog ranges lie immediately to the south.
Snowdon, or Yr Wyddfa, is a mountain in the Snowdonia region of North Wales. It has an elevation of 1,085 metres (3,560 ft) above sea level, which makes it both the highest mountain in Wales and the highest in the British Isles south of the Scottish Highlands. Snowdon is designated a national nature reserve for its rare flora and fauna, and is located within Snowdonia National Park.
The Rhinogydd 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.
The Cambrian Mountains are a series of mountain ranges in Wales. The term Cambrian Mountains used to apply to most of the upland of Wales, and comes from the country's Latin name Cambria. Since the 1950s, its application has become increasingly localised to the geographically homogeneous Mid Wales uplands, known in Welsh as Elenydd, which extend from Plynlimon (Pumlumon) to Radnor Forest in the east and Mynydd Mallaen to the south. This barren and sparsely populated 'wilderness' has been referred to as the Desert of Wales. The area includes the sources of the River Severn and River Wye and was unsuccessfully proposed as a national park in the 1960s and 1970s. The highest point of the range is Plynlimon, at 2,467 feet (752 m).
The Glyderau are a mountain group in Snowdonia, North Wales. The name derives from the highest peaks in the range, Glyder Fawr and Glyder Fach. According to Sir Ifor Williams, the word "Glyder" derives from the Welsh word "Cludair", meaning a heap of stones.
Glyder Fawr is a mountain in Snowdonia, Wales, the highest peak in the Glyderau range at just over 1,000 metres. It is the fifth-highest mountain in Wales and has several walking and scrambling routes leading to its summit. According to Sir Ifor Williams, the word "Glyder" derives from the Welsh word "Gludair", meaning a heap of stones.
Pen-y-Pass is a mountain pass in Snowdonia, Gwynedd, north-west Wales. It is a popular location from which to walk up Snowdon, as three of the popular routes can be started here. Glyder Fawr, to the north, is also accessible from here.
Y Garn is a mountain in Snowdonia, North Wales, part of the Glyderau.
The national parks of Wales are managed areas of outstanding landscape in Wales, United Kingdom where some forms of development are restricted to preserve the landscape and natural environment. Together, they cover 20% of the land surface of Wales and have a resident population of over 80,000 people. Each National Park Authority is a free-standing body within the local government framework.
Arenig Fawr is a mountain in Snowdonia, North Wales, close to Llyn Celyn reservoir, alongside the A4212 between Trawsfynydd and Bala.
Dduallt is a mountain in central Snowdonia, north Wales. It is the sister peak of Rhobell Fawr.
Cwm Idwal is a cirque in the Glyderau range of mountains in northern Snowdonia, the national park in the mountainous region of North Wales. Its main interest is to hill walkers and rock climbers, but it is also of interest to geologists and naturalists, given its combination of altitude, aspect (north-facing) and terrain. In a 2005 poll conducted by Radio Times, Cwm Idwal was ranked the 7th greatest natural wonder in Britain.
Pitt's Head is a distinctive rock located at grid reference SH576515, close to the A4085 road in Gwynedd, Wales. Its distinction lies in a resemblance to the profile of politician William Pitt the Younger.
Aran Benllyn is a subsidiary summit of Aran Fawddwy in southern Snowdonia, North Wales, Wales, United Kingdom. It is the second highest peak in the Aran mountain range.
Moel Llyfnant is a mountain in the southern portion of the Snowdonia National Park in Gwynedd, Wales. It is a peak in the Arenig mountain range. It lies to the west of Arenig Fawr. It has one notable top, the twin peaked Gallt y Daren, being at the end of its west ridge.
Yr Arddu is a large hill in Snowdonia, Wales. 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 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.
Fforest Fawr Geopark is a Geopark in the Brecon Beacons National Park, south Wales. It is the first designated Geopark in Wales having gained membership of both the European Geoparks Network and the UNESCO-assisted Global Network of National Geoparks in October 2005. The Geopark aims to promote and support sustainable tourism and other opportunities to improve the economy of the area whilst safeguarding the natural environment. Its aims largely coincide with the statutory duties and purpose of the National Park within which it sits.
The Snowdon Volcanic Group is an Ordovician lithostratigraphic group in Snowdonia, north-west Wales. The name is derived from Snowdon, the highest peak in Wales where it outcrops. This assemblage of rocks has also been referred to as the Snowdon Volcanic Series.
Pen Ty-Nant is a hill within the Snowdonia National Park in Gwynedd, North Wales.
The geology of Snowdonia National Park in North Wales is dominated by sedimentary and volcanic rocks from the Cambrian and Ordovician periods with intrusions of Ordovician and Silurian age. There are Silurian and Cenozoic sedimentary rocks on the park's margins. The succession was intensely faulted and folded during the Caledonian Orogeny. The region was uplifted as the North Atlantic Ocean opened during the Cenozoic. The current mountainous landscape arises from repeated glaciations during the Quaternary period.
