Pen yr Ole Wen

Ffynnon Lloer (Welsh : Source of [the] Moon) is a lake in the Carneddau range of mountains in Snowdonia, North Wales. It lies below the peaks of Pen yr Ole Wen and Carnedd Dafydd at a height of 2,225 feet (678 m) and covers an area of some 6 acres (2.43 ha). The remains of two wartime aircraft, which crashed in 1942 and 1943, lie on the slopes round the lake.Afon Lloer, its outflow, flows into Llyn Ogwen.

Foel Meirch is a top of Carnedd Dafydd in the Carneddau range in Snowdonia, Wales. It offers commanding views of Carnedd Llewelyn and Yr Elen, and the Ysgolion Duon Cliffs.

Carnedd Dafydd is a mountain peak in the Carneddau range in Snowdonia, Wales, and is the third highest peak in Wales, or the fourth if Crib y Ddysgl on the Snowdon ridge is counted. Situated south-west of Carnedd Llewelyn and north of Pen yr Ole Wen, Carnedd Dafydd is on the main ridge of the Carneddau, and on the border between Gwynedd and Conwy. The average annual temperature of the mountain is around 3–4 °C (38-40 °F). Carnedd Dafydd rises to height of 1,044 m (according to OS maps detail) and is usually climbed by first ascending Pen yr Ole Wen and then following the ridge along to Carnedd Dafydd, though it is also possible to make a direct ascent from Tal y Llyn Ogwen, first following the stream, Afon Lloer, to the mountain lake of Ffynnon Lloer then climbing up the slope to the summit. Like most of the summits in the southern Carneddau, it has a flat, boulder-strewn summit plateau. Immediately to the north lie the crags of Ysgolion Duon, well known to climbers. The origin of its name, which translates as Dafydd's (or David's) cairn, like that of its neighbouring peak, Carnedd Llewelyn (Llywelyn's cairn), are named after Llywelyn ap Gruffudd, the last independent prince of Wales, and his younger brother, Dafydd ap Gruffudd. The nearby peak Carnedd Lladron, commonly known as Carnedd Uchaf, has now been renamed by O.S. Carnedd Gwenllian in memory of Llywelyn's daughter Lady Gwenllian. Dafydd was captured at Nanhysglain, near Bera Mawr, on 21 June 1283; taken to Shrewsbury, he was hanged, drawn and quartered.

The Nant Ffrancon Pass in Snowdonia, North Wales is at 312 metres (1,024 ft) at Pont Wern-gof, about one-third of a mile beyond the eastern end of Llyn Ogwen. The A5 road crosses it between Llyn Ogwen and Bethesda, Gwynedd

Ogwen Cottage Outdoor Pursuits Centre is situated beside Llyn Ogwen, in Gwynedd, Wales. It is owned by the National Trust, who bought the property at auction in October 2014 for £450,000. It was formerly for many years part of Birmingham City Council's Outdoor Learning Service, providing outdoor education, and with links to the climbing community.

The Welsh 1000m Peaks Race takes place on the first Saturday in June each year. The 32 km route is also known as the Snowdonia Summits Marathon as competitors have to reach the top of all the 1000 metre peaks in Wales. Carnedd Llewelyn 1064m (3491 feet) Carnedd Dafydd 1044m (3425 feet) Glyder Fawr 1001m (3281 feet) Garnedd Ugain 1065m (3493 feet) and Snowdon (Yr Wyddfa) 1085m (3560 feet)Runners also have to pass through several other checkpoints; this gives a total of around 8000 feet of ascent for competitors. In previous years only the lower slopes of the Glyderau would be crossed, however in September 2010, the summit of Glyder Fawr was remeasured at 1001m.The organisers of the race included this summit from 2011. It is a tough endurance event and required navigational skills. The idea was the brainchild of Ron James, the warden of Ogwen Cottage Outdoor Pursuits Centre, along with Dr Ieuan Jones, who invited 60 people to participate in a trial event in 1970. The first race proper was held in 1971 with men starting from the shoreline at Abergwyngregyn, on the shoreline of Conwy Bay, and ladies from the Ogwen Valley. Both finished on the summit of Snowdon after which entrants were still responsible for their own safety and descent to the valley. The early events were for mountaineers, with kit checks to ensure boots were adequate & rucksacks a certain minimum weight, and groups such as West Bromwich Mountaineering Club participated every year. The Army supported the whole event, providing checkpoints throughout the route. Later a Fell running class was introduced and a team event. The Gorphwysfa Club took over the race organisation from the military in the 1990s. The fastest times are 3h 27m 20s recorded by Gavin Bland in 1999 and, for women, 4h 2m 39s by Angela Mudge also in 1999. The record for the team event (the accumulated times of the 3 best finishers) is 13h 41m 56s set in 1996 by the Reserves team of the Royal Regiment of Wales. The event is currently sponsored by the First Hydro Company.

Dyffryn Ogwen, or Ogwen Valley, is a valley mostly located in the Welsh county of Gwynedd. The upper section of the valley, east of Llyn Ogwen, lies in the county of Conwy.

Llyn Ogwen (; Welsh: [ˈɬɪn ˈɔɡʊɛn]) is a ribbon lake in north-west Wales. It lies alongside the A5 road between two mountain ranges of Snowdonia, the Carneddau and the Glyderau. Somewhat unusually, the county boundary at this point is drawn so that the lake itself lies in the county of Gwynedd, but all the surrounding land (excluding the outflow) lies in Conwy County Borough. Llyn Ogwen lies at a height of about 310 metres above sea level and has an area of 78 acres (320,000 m2), but is a very shallow lake, with a maximum depth of only a little over 3 metres. It is fed by a number of streams from the slopes of the mountains which surround it, which include Tryfan and Pen yr Ole Wen. The largest of these streams is Afon Lloer, which flows from Ffynnon Lloer. It is said that after the Battle of Camlann (King Arthur's final battle), Sir Bedivere (Bedwyr) cast the sword Excalibur into Llyn Ogwen, where it was caught by the Lady of the Lake. Tryfan is said to be Sir Bedivere's final resting-place. According to the writer Jonah Jones:"J. M. Archer Thomson, a headmaster of Llandudno School and a pioneer rock climber in Snowdonia quotes a strange legend from a Welsh magazine concerning Llyn Ogwen. A Shepherd happened upon a cave in Craig Cwrwgl above the lake containing the treasure of King Arthur. In the midst of the commotion caused by this intrusion, he turned to the lake, and 'behold thereon a coracle in which sat three women of more than mortal beauty, but the dread aspect of the rower would have filled the stoutest heart with terror.' E. W. Steeple, who recorded this legend, suggests it 'seems a little obscure, and it may be that it has become involved with another story', probably that of Llyn Llydaw." Llyn Ogwen is the source of the Afon Ogwen which flows north to reach the sea near Bangor. A dam was built in the Afon Ogwen at Ogwen Bank, in the early 20th century, to raise the level of the river in order to provide water for the use in the nearby Penrhyn Quarry. The lake is popular with anglers and is said to contain excellent trout.

Afon Lloer is a small river in Snowdonia in north-west Wales. It is the outflow from Ffynnon Lloer, a lake in the Carneddau mountains, and it flows into Llyn Ogwen.

Llyn Idwal is a small lake (approximately 800 m by 300 m, or 28 acres) that lies within Cwm Idwal in the Glyderau mountains of Snowdonia.It is named after Prince Idwal Foel, a grandson of Rhodri Mawr, one of the ancient Kings of Wales. Legend states that the king's unfortunate offspring was murdered by being drowned in the lake. In fact Idwal Foel died in battle against the Saxons in 942 and an alternate version claims that he was cremated beside the lake, as was the burial custom for Celtic nobility. A number of small streams flow into Llyn Idwal from around Cwm Idwal. One small river flows out and joins the Afon Ogwen river at Pont Pen-y-Benglog near Ogwen Cottage, immediately above the Rhaeadr Ogwen waterfall.

Tryfan Welsh pronunciation: [ˈtrəvan]) is a mountain in the Ogwen Valley, Snowdonia, Wales. It forms part of the Glyderau group, and is one of the most recognisable peaks in Britain, having a classic pointed shape with rugged crags. At 917.5 metres (3,010 feet) above sea level, it is the fifteenth-highest mountain in Wales. Tryfan was voted Britain's favourite mountain by Trail magazine.Between the mid-1980s and June 2010, its accepted height was 915 metres (3,002 ft). However, it was resurveyed using accurate GPS measurements and found to be 2.4 metres (eight feet) higher (which the pre-1980s surveys also recorded).Tryfan is said to be the final resting-place of Sir Bedivere (Bedwyr) of Arthurian legend.

Cwm Idwal is a cirque (or corrie) 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 (relatively high in UK terms), aspect (north-facing) and terrain (mountainous and rocky). In a 2005 poll conducted by Radio Times, Cwm Idwal was ranked the 7th greatest natural wonder in Britain.
