Llyn Peris is a lake in Snowdonia, Wales, approximately 1.8 km long and situated close to the villages of Llanberis and Nant Peris. The lake was formed glacially and is an example of a moraine-dammed lake. Llyn Peris is named after Saint Peris, an early Christian saint of whom little is known. The lake is flanked on one side by the mountain Elidir Fawr and the former slate quarry of Dinorwig. Above the opposite bank are the hills of Derlwyn and Clogwyn Mawr and a rock formation known as the Lady of Snowdon, due to its resemblance to a human face. The ruins of Dolbadarn Castle are also located on a mound above the lake. Yr Wyddfa commonly known as Snowdon in English, is the highest mountain in Wales, at an elevation of above sea level, and the highest point in the British Isles south of the Scottish Highlands. It is located in Snowdonia National Park (") in Gwynedd, and has been described as "probably the busiest mountain in Britain". It is designated as a national nature reserve for its rare flora and fauna. Scuba diving is a mode of underwater diving in which the scuba diver uses a self-contained underwater breathing apparatus (scuba) which is completely independent of surface supply, to breathe underwater. Scuba provides the diver with the advantages of mobility and horizontal range far beyond the reach of an umbilical hose attached to surface-supplied diving equipment (SSDE).
  Scuba divers engaged in armed forces covert operations may be referred to as frogmen, combat divers or attack swimmers. The Deceangli or Deceangi (Welsh: Tegeingl) were one of the Celtic tribes living in Britain, prior to the Roman invasion of the island. The tribe lived mainly in what is now north-east Wales, though it is uncertain whether their territory covered only the modern counties of Flintshire, Denbighshire and part of Cheshire in what is now present day England or whether it extended further west. The tribe occupied an area between the Clwyd and Dee rivers. They lived in hill forts running in a chain through the Clwydian Range and their tribal capital was Canovium. Climbing is the activity of using one's hands, feet, or any other part of the body to ascend a steep object. It is done recreationally, competitively, in trades that rely on it, and in emergency rescue and military operations. It is done indoors and out, on natural and manmade structures. A lake is an area of variable size filled with water, localized in a basin, that is surrounded by land, apart from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, and therefore are distinct from lagoons, and are also larger and deeper than ponds, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which are usually flowing. Most lakes are fed and drained by rivers and streams. Gnaeus Julius Agricola (13 June 40  23 August 93) was a Gallo-Roman general responsible for much of the Roman conquest of Britain. Written by his son-in-law Tacitus, the "De vita et moribus Iulii Agricolae" is the primary source for most of what is known about him, along with detailed archaeological evidence from northern Britain. The Silures were a powerful and warlike tribe or tribal confederation of ancient Britain, occupying what is now south east Wales and perhaps some adjoining areas. They were bordered to the north by the Ordovices; to the east by the Dobunni; and to the west by the Demetae. Walking (also known as ambulation) is one of the main gaits of locomotion among legged animals, and is typically slower than running and other gaits. Walking is defined by an 'inverted pendulum' gait in which the body vaults over the stiff limb or limbs with each step. This applies regardless of the number of limbs - even arthropods, with six, eight or more limbs, walk. The Dinorwig Power Station is a pumped-storage hydroelectric scheme, near Dinorwig, Llanberis in Snowdonia national park in Gwynedd, north Wales. Its purpose is not to help meet peak loads but as a "Short Term Operating Reserve", to provide a fast response to short-term rapid changes in power demand. The Ordovices were one of the Celtic tribes living in Great Britain before the Roman invasion. Their tribal lands were located in present-day North Wales and England between the Silures to the south and the Deceangli to the north-east. The Ordovices were conquered by the Roman governor Gnaeus Julius Agricola in the campaign of AD 7778. Snowdonia is a mountainous region in north Wales and a national park of in area. It was the first to be designated of the three national parks in Wales, in 1951. Gwynedd is an area in north-west Wales, named after the old Kingdom of Gwynedd. As a local government area, it is the second biggest in Wales in terms of geographical area and also one of the most sparsely populated. A majority of the population are Welsh-speaking. The name Gwynedd is also used for a preserved county, covering the two local government areas of Gwynedd and the Isle of Anglesey. Culturally and historically, the name can also be used for most of North Wales (for instance, the area covered by the Gwynedd Constabulary), roughly corresponding to the territory of the Kingdom of Gwynedd at its greatest extent. The current area is 2,548 square km (983.78 sq miles, slightly smaller than Luxembourg) with a population as measured in the 2011 Census of 121,874. The term mountaineering describes the sport of mountain climbing, including ski mountaineering. Hiking in the mountains can also be a simple form of mountaineering when it involves scrambling, or short stretches of the more basic grades of rock climbing, as well as crossing glaciers. Llanberis is a village in Gwynedd, northwest Wales, on the southern bank of the lake Llyn Padarn and at the foot of Snowdon, the highest mountain in Wales. It is a popular centre for outdoor activities in Snowdonia, including walking, mountaineering, climbing, mountain biking and pony trekking as well as water sports such as Scuba Diving. The international fell race known as the Snowdon Race (Welsh: "Ras Yr Wyddfa") to the summit of Snowdon begins in the village.  Llyn Padarn is a glacially formed lake in Snowdonia, Gwynedd, north Wales, and is an example of a moraine dammed lake. The lake is approximately long (about 240 acres) and at its deepest point is deep, and is one of the largest natural lakes in Wales. At its south-eastern end it is linked to the neighbouring Llyn Peris (which forms the lower reservoir of the Dinorwig power station). The busy village of Llanberis lies on the southern banks of the lake. Wales is a country that is part of the United Kingdom and the island of Great Britain. It is bordered by England to the east, the Irish Sea to the north and west, and the Bristol Channel to the south. It had a population in 2011 of 3,063,456 and has a total area of . Wales has over of coastline and is largely mountainous, with its higher peaks in the north and central areas, including Snowdon, its highest summit. The country lies within the north temperate zone and has a changeable, maritime climate. Mountain biking is the sport of riding bicycles off-road, often over rough terrain, using specially designed mountain bikes. Mountain bikes share similarities with other bikes, but incorporate features designed to enhance durability and performance in rough terrain. Dinorwig is a small village located high above Llyn Padarn , near Llanberis , in Wales . It is thought that it was part of the territory of the Ordovices tribe , and that ' Dinorwig ' means `` Fort of the Ordovices '' . The village has a long history of slate quarrying . The Romans used local slate for the construction of Segontium , and slates from the valley were used in the construction of Caernarfon Castle . The main local quarry was the Dinorwic Quarry , which was worked from the late 1770s until 1969 . After the First World War , cheaper alternative roofing materials became available and production at the quarry declined . This led to a decline in the fortune of the village itself and many moved away to nearby towns such as Bangor and Caernarfon . Today , the village shares its name with a pumped storage hydroelectric power station , Dinorwig power station . The village is also the location of the Blue Peris Mountain Centre , a residential outdoor activities centre operated by Bedford Borough Council and Central Bedfordshire Council . Part of the film Willow was shot in the disused Dinorwig Quarry , in June 1987 . The village 's population is approximately 200 .
