Llyn Llydaw

Crib Goch is described as a "knife-edged" arête in the Snowdonia National Park in Gwynedd, Wales. The name means "red ridge" in the Welsh language. The highest point on the arête is 923 metres (3,028 ft) above sea level. All routes which tackle Crib Goch are considered mountaineering routes in winter or scrambles in summer—meaning that they must cross "graded territory" as defined in Steve Ashton's Scrambles in Snowdonia. The easiest of these lines (the ‘bad step’ part of the route) is given a scrambling grade of Grade 1 (the most difficult being Grade 3—routes more difficult than Grade 3 are considered rock climbs).

Lliwedd Bach is a top of Y Lliwedd in the Snowdonia National Park, North Wales. It is the last "top" on the main ridge of Y Lliwedd, the other being Y Lliwedd East Peak. A broad ridge at around 580m carries on northwards until the subsidiary summit of Gallt y Wenallt is reached. The summit is unmarked and offers good views of Y Lliwedd's cliffs, Snowdon (Yr Wyddfa) and Crib Goch.

Y Lliwedd East Peak is the twin top of Y Lliwedd in the Snowdonia National Park, North Wales. It is only 5 metres shorter than the main summit of Y Lliwedd. The summit marked by a small pile of stones, the views being similar to Y Lliwedd, except for Gallt y Wenallt being in view.

Y Lliwedd is a mountain, connected to Snowdon in the Snowdonia National Park, North Wales. Its summit lies 898 metres (2,946 ft) above sea level. The eastern flanks are steep cliffs rising above Glaslyn and Llyn Llydaw. Y Lliwedd is the most conspicuous of the peaks for those who approach Snowdon via the Miners' and Pyg tracks. Few that summit Snowdon continue over to Y Lliwedd as the challenge of Wales' highest peak is enough, leaving Y Lliwedd quiet and peaceful even when queues are forming at the summit of Snowdon. Hikers and mountaineers often pass over Y Lliwedd when walking the Snowdon Horseshoe. The noted British climber George Mallory undertook many of his early climbs here. It was also the site of considerable training activity for the 1953 British Everest Expedition. The north face of Y Lliwedd was explored in the late 19th century and in 1909 was the subject of the first British climbing guide, The Climbs on Lliwedd by J. M. A. Thomson and A. W. Andrews. Two subsidiary peaks of Y Lliwedd are listed as Nuttalls: Lliwedd Bach 818 metres (2,684 ft): SH628532 and Y Lliwedd East Peak 893 metres (2,930 ft): SH623532.

Arfon is a constituency of the Senedd. It was 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 nine constituencies in the North 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.

Glaslyn (Welsh: Blue lake) is a lake in the Snowdonia National Park in Gwynedd, north-west Wales.

The Llanberis Pass (Welsh: Bwlch Llanberis; alternative English name, Pass of Llanberis) in Snowdonia carries the main road (A4086) from the south-east to Llanberis, over Pen-y-Pass, between the mountain ranges of the Glyderau and the Snowdon massif. At the bottom of the pass is the small village of Nant Peris.

Gallt y Wenallt is a subsidiary summit of Y Lliwedd in Snowdonia National Park, north Wales. It lies at the end of the north ridge. Its northern face is reputed to be the longest slope in Snowdonia, being close to 2000 ft. It is also the last nail in the "completist's" Snowdon Horseshoe. The summit is grassy and is marked with a small cairn. In clear visibility, the view down to Llyn Gwynant is regarded as one of the finest in Snowdonia.It is the resting place of famous oil man and sailor, Emrys Nye Hughes.

Llyn Gwynant is a lake in Snowdonia, Wales. Llyn Gwynant lies on the River Glaslyn, in the Nant Gwynant valley, and is about 1¼ miles (2 km) north east of Llyn Dinas; the village of Bethania lies between them. Snowdon lies 2 miles (3 km) to the north west. The lake is natural, having been formed by glacial action and is 120 acres (50 hectares) in size. It is a popular place for canoeing and kayaking with easy access from the A498 road which runs along its south bank. It was used as a filming location in the 2003 film 'Lara Croft Tomb Raider: The Cradle of Life'. The view towards Llyn Gwynant and Moel Hebog is one of the most photographed in Snowdonia.

Dinas Cromlech or Dinas y Gromlech is a distinctive rhyolite rock outcrop at the Llanberis Pass, in Snowdonia, northwest Wales, which has a distinctive "open book" shape that is clearly visible from the road (A4086), and is very popular for rock climbers, and features in the history of the sport.

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 (the Miners Track, the Pyg Track and the ascent via Crib Goch) can be started here. Glyder Fawr, to the north, is also accessible from here. Situated at the high point of the Llanberis Pass at an elevation of 359 metres (1,178 ft) – about a third of the height of Snowdon – the road was built in the 1830s to allow ore from the mines on Snowdon to be transported to Llanberis. It would be taken down the Miners Track to a store-house at Pen-y-Pass first. Previously, the miners had had to move the ore over the Snowdon summit and down to Beddgelert, which is located at around a third the height of Snowdon. The Llanberis pass road extends beyond Pen-y-Pass to join the Beddgelert-to-Capel Curig road at the Pen-y-Gwryd hotel. That notable climbing hotel was used as a base by Sir John Hunt, Baron Hunt and his team whilst training for the successful 1953 expedition to Mount Everest and equipment and autographs from that and other expeditions may be seen in the Everest Room. The former Gorphwysfa Hotel at Pen-y-Pass is now a youth hostel, bar and café operated by YHA, and opposite is an information centre and café and a Snowdonia National Park-run car park. There is also a car park half way down Llanberis Pass in Nant Peris village as well as others in Llanberis village. There is a park and ride bus service to Pen-y-pass car park, which is the hub of the year-round Sherpa bus network provided by Express Motors and GHA Coaches. This service links Pen-y-Pass to Llanberis, Capel Curig, Betws-y-Coed, Beddgelert, Porthmadog, Rhyd Ddu and Waunfawr.

Snowdon () or Yr Wyddfa (pronounced [ər ˈʊɨ̞̯ðva] (listen)) is the highest mountain in Wales, at an elevation of 1,085 metres (3,560 ft) above sea level, and the highest point in the British Isles outside the Scottish Highlands. It is located in Snowdonia National Park (Parc Cenedlaethol Eryri) in Gwynedd (historic county of Caernarfonshire). It is the busiest mountain in the United Kingdom and the third most visited attraction in Wales; in 2019 it was visited by 590,984 walkers, with an additional 140,000 people taking the train. It is designated as a national nature reserve for its rare flora and fauna. The rocks that form Snowdon were produced by volcanoes in the Ordovician period, and the massif has been extensively sculpted by glaciation, forming the pyramidal peak of Snowdon and the arêtes of Crib Goch and Y Lliwedd. The cliff faces on Snowdon, including Clogwyn Du'r Arddu, are significant for rock climbing, and the mountain was used by Edmund Hillary in training for the 1953 ascent of Mount Everest. The summit can be reached by a number of paths (there are six main paths) and by the Snowdon Mountain Railway, a rack railway opened in 1896 which carries passengers the 4+3⁄4 miles (7.6 kilometres) from Llanberis to the Summit station. The summit building, called Hafod Eryri, houses a cafe and is open only when the railway is operating; it opened in 2009 to replace one built in the 1930s. The railway generally operates from March to the end of October, with trains running to the summit station from May. The daily running schedule depends on weather and customer demand. Snowdon is one of three mountains climbed as part of the National Three Peaks Challenge.
