National Slate Museum

Gilfach Ddu (also known as the Dinorwic Slate Quarry Workshops) are a series of well preserved Grade I listed industrial buildings built to serve the Dinorwic slate quarry near the Llanberis in Caernarfonshire, North Wales. The workshops are a complex of repair and maintenance buildings, that were built in 1870 to build and maintain the machinery used in the quarry. The complex includes saw sheds, patternmaking shops, a foundry with copula, blacksmiths shops, fitting shops, stores, engine sheds, a canteen, the chief engineers house, a hand operated crane and two waterwheels which provided the site with its power. Since 1972 the buildings have housed the National Slate Museum.

Gilfach Ddu (LLR) railway station is an intermediate station on the Llanberis Lake Railway (LLR), located in Llanberis, Gwynedd, Wales. Most of the LLR was laid around 1970 on part of the trackbed of the closed and lifted Padarn Railway. The line opened between Gilfach Ddu and Cei Llydan on 28 May 1971, being extended northwards to Penllyn (LLR) in 1972. For thirty years Gilfach Ddu was the new line's southern terminus, situated a short distance south of the site of the Padarn Railway's former workmen's station, also named Gilfach Ddu. In 2003 a wholly new extension was opened south westwards, with Llanberis (LLR) station as the line's new southern terminus. With this extension Gilfach Ddu (LLR) changed from a terminus to a through station. The line and station primarily serve tourists and railway enthusiasts.The station has one platform.

The Dinorwig Power Station (; Welsh: [dɪˈnɔrwɪɡ]), known locally as Electric Mountain, or Mynydd Gwefru, is a pumped-storage hydroelectric scheme, near Dinorwig, Llanberis in Snowdonia national park in Gwynedd, north Wales. The scheme can supply a maximum power of 1,728 MW (2,317,000 hp) and has a storage capacity of around 9.1 GWh (33 TJ).

Dolbadarn Castle (English: dol-BAD-an; Welsh: Castell Dolbadarn Welsh pronunciation: [kastɛɬ dɔl'badaːn]) is a fortification built by the Welsh prince Llywelyn the Great during the early 13th century, at the base of the Llanberis Pass, in northern Wales. The castle was important both militarily and as a symbol of Llywelyn's power and authority. The castle features a large stone keep, which historian Richard Avent considers "the finest surviving example of a Welsh round tower". In 1284 Dolbadarn was taken by Edward I, who removed some of its timbers to build his new castle at Caernarfon. The castle was used as a manor house for some years, before falling into ruin. In the 18th and 19th centuries, it was a popular destination for painters interested in Sublime and Picturesque landscapes. It is now owned by Cadw and managed as a tourist attraction, and is protected as a grade I listed building.

Llanberis (LLR) railway station is the southern terminus of the Llanberis Lake Railway (LLR), located in Llanberis, Gwynedd, Wales. The line and station primarily serve tourists and railway enthusiasts.Most of the LLR was laid around 1970 on the trackbed of the closed and lifted Padarn Railway. The line opened between Gilfach Ddu (LLR) and Cei Llydan on 28 May 1971, being extended northwards to Penllyn (LLR) in 1972. For thirty years the new line's southern terminus was Gilfach Ddu (LLR), situated a short distance south of the site of the Padarn Railway's former workmen's station, also named Gilfach Ddu. In 2003 a wholly new extension was opened south westwards, with Llanberis (LLR) station as the line's new southern terminus. The single platform station stands opposite Llanberis (SMR) station, the lower terminus of the Snowdon Mountain Railway, and not far from the site of the long-closed Llanberis standard gauge station.

Llanberis (SMR) railway station is the lower terminus of the Snowdon Mountain Railway, located in Llanberis, Gwynedd, Wales. The station houses the headquarters of the tourist railway which climbs for 4.7 miles (7.6 km) from Llanberis to the summit of Snowdon, the highest peak in Wales. The station stands in the valley bottom at an altitude of (353 ft (108 m)), the summit station stands at 3,493 feet (1,065 m), 68 feet (21 metres) below the summit of the mountain. The station opened with the railway on 6 April 1896, but closed the same day following an accident. It reopened on 9 April 1897, without mishap and has operated since, even throughout most of the Second World War, as there was military activity near the mountaintop.The station has two platforms. The first stretch of line is uphill at 1 in 50, steep for a main line but shallow compared with the 1 in 6 incline that begins shortly afterwards. The line's engine shed and workshop are visible from the platform ends.

Llanberis railway station was located in Llanberis, Gwynedd, Wales. It was a short walk from the Llanberis station of the Snowdon Mountain Railway. It opened 1 July 1869, and closed for regular passenger services in 1930. But it was still used by summer excursion trains until 7 September 1962 and freight services until 3 September 1964.The last fare-paying passenger service was an enthusiasts' special on 20 October 1964.An engine shed stood between the goods yard and the 42' turntable beyond the end of the platform. From 1948 to 1962 some excursion trains used an observation car which was turned round on the turntable so occupants always had an open view. The shed closed around 1915 and had been demolished by 1919. The goods yard was the last part of the working railway to close. The station had a ticket platform at its northern end. A LMS caravan was sited opposite from 1934 to 1939. A camping coach was also positioned here by the London Midland Region from 1954 to 1959 (two coaches in 1954 only).The line was lifted in 1965. The station site and most of the trackbed as far as Cwm-y-Glo are now occupied by the improved A4086, which bypasses the centre of Llanberis. In 2015 the original station building was in use as a craft shop.

Padarn Halt was a passenger only railway station located in Llanberis, Gwynedd, Wales, on the western shore of Llyn Padarn. It opened on 21 November 1936 and closed on the outbreak of the Second World War. The line through the station remained in use for excursions until 1962 and for freight until 1964; it was lifted in 1965. The LMSR closed the Llanberis branch to regular passenger services in 1930, though frequent Summer excursions continued to run. In 1934 the company reinstated a regular Saturdays only train specifically to serve Caernarfon market. In many parts of Britain "Market Trains" were an established part of local commerce and social life in a way which has passed into history. Llanberis station was not in the centre of Llanberis, so the company built the halt half a mile from the terminus specifically for this market traffic. The halt opened on 21 November 1936, from which time the market trains used the halt there instead of at Llanberis station. The halt consisted of an unlit single wooden platform on trestles, with a very small wooden waiting shelter at its southern end. It was accessed by a gravel footpath which continued over the tracks to the lakeside by a foot crossing. The 1939 working timetable shows that some excursions made unadvertised stops at the halt.The track bed from Llanberis through the site of the halt (at what is now the lakeside entrance to the industrial estate) as far as Cwm-y-Glo is now occupied by the improved A4086, which by-passes the centre of Llanberis. No trace of the station remains.

Pete's Eats is a cafe in Llanberis, North Wales, popular amongst walkers and climbers in the Snowdonia region of mountains. Llanberis, at the foot of Snowdon, is one of the traditional starting points for climbs in the Snowdonia National Park. The cafe has long been an important centre for climbers, described as "one of the most famous mountaineering hangouts in Britain". It even received a small mention in the New York Times as "cheap and filling" and "rowdy fun".

Llyn Peris is a lake in Snowdonia, Wales, approximately 1.8 km long and situated close to the villages of Llanberis and Nant Peris, and the smaller twin of Llyn Padarn. 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. The lake now forms the lower reservoir of Dinorwig power station, and the administrative buildings for the station are situated on the lake shore. Water is released into the lake from Marchlyn Mawr (the upper reservoir) to produce electricity during periods of peak demand. This water is, in turn, pumped back to the upper reservoir using electricity purchased at off-peak periods. The water level of the lake therefore varies considerably, depending on UK electricity demand. Excess water from the lake drains into Llyn Padarn. During construction of the power station, when the capacity of the lake was increased considerably at this time, with the removal of a large quantity of slate waste, rare Welsh Arctic char fish were removed to four other lakes in the neighbouring Carneddau mountains, namely Ffynnon Llugwy, Llyn Cowlyd, Llyn Melynllyn and Llyn Dulyn, where they are still to be found. Although Llyn Peris itself was not restocked, some char have found their way back to the lake. Parts of the lake shore are designated as a Site of Special Scientific Interest for Glacial Geology.

Dinorwig, sometimes spelled Dinorwic ( din-OR-wig; ; Welsh: [dɪˈnɔrwɪɡ]), is a village located high above Llyn Padarn, near Llanberis, in Wales. The name is shared with the fort of Dinas Dinorwig, also within the community of Llanddeiniolen, on a foothill 6 kilometres (3.7 mi) from Dinorwig village and 3 kilometres (1.9 mi) from the Menai Strait and also with Port Dinorwic, the anglicised name of Y Felinheli.

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 2 miles (3.2 km) long (about 240 acres) and at its deepest point is 94 feet (29 m) 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. Most of Llyn Padarn is owned by Gwynedd Council and is part of Padarn Country Park. Whilst kayaking, rowing and sailing are permitted on the lake, powered craft require permission to use it. Bangor University Rowing Club row at Llyn Padarn. In April 2014 Llyn Padarn was designated as Bathing Water under the Bathing Water Directive (2006/7/EC). The outflow of Llyn Padarn is on the northern shore and is called Afon Rhythallt, which passes by the village of Brynrefail, Gwynedd and becomes Afon Seiont below Pont Rhythallt, near Llanrug. It reaches the sea at Caernarfon. Padarn Country Park is located on the northern flank of the lake, including Coed Allt Wen, a rare and ancient sessile oak woodland. Both the woodland and Llyn Padarn are designated as Sites of Special Scientific Interest. The Llanberis Lake Railway also runs along its eastern bank and various recreational activities take place on the lake, especially during the summer. These include canoeing, boating and fishing. The lake was the venue for the rowing events of the 1958 British Empire and Commonwealth Games. Former local bus company Padarn Bus, which operated between 1979 and 2014 from a base at nearby Llanberis, was named after the lake.Llyn Padarn is named after Padarn, an early 6th century saint, who has a church dedicated to him in Llanberis.
