Snowdon Ranger railway station

Llyn Cwellyn (Llyn Quellyn in some antiquated texts) is a reservoir in North Wales which supplies drinking water to parts of Gwynedd and Anglesey. It lies on the Afon Gwyrfai in Nant y Betws between Moel Eilio and Mynydd Mawr in the northern part of Snowdonia National Park. It has an area of 215 acres (0.87 km2), and is over 120 ft (37 m) deep. At the southern end is the small village of Rhyd Ddu. Although it is now dammed at the northern end - below the Castell Cidwm ridge, near the village of Betws Garmon - this has not substantially increased the size of the natural glacial moraine lake that has existed since the last ice age. The lake is very deep and is one of the few lakes in Wales to support a natural population of Arctic char. The lake is also home to brown trout and there are otters that are regularly seen at the Castell Cidwm end. The lake has shared ownership between Lawrence Jones (businessman), owner of the Castell Cidwm estate at the northern end, and Welsh water, who own the right-hand side which supplies the weir. The lake was originally owned by the Marquis of Anglesey who used the Castell Cidwm country house as his hunting lodge. The A4085 runs past the lake; however, there are no lay-bys for picnics and the east side is now considered a Nature Reserve, and fishing is not permitted in the tree-lined area beside the road all the way down to Castell Cidwm. Fishing permits can be purchased for Cwellyn and fly fishing anglers can expect to catch wild brown trout here, which are abundant and often found along the shoreline which has easy wading. Char and salmon can also be caught, usually from the boats available for hire from the Cwellyn hotel. This lake is particularly dangerous when paddle boarding, wild swimming or kayaking in bad weather, as fast winds come down off Snowdon and through the valley, making it hard to travel back up the lake. This lake is a reservoir and electric engines only are permitted; electric engines with 50lb thrust are quite adequate to get around the lake, even in windy conditions. On the far side of the lake the land was planted as a commercial soft-wood forest and is now owned by Natural Resources Wales; however, logging has been stopped to prevent the water in the lake being polluted by silt generated by logging activities. In 2005 an outbreak of Cryptosporidiosis in the water supply drawn from the lake led to improvements being planned for the water treatment works. Work started in 2009 2 miles (3.2 km) down stream on an updated water treatment plant which included froth flotation, upward flow clarifiers and UV sterilisation of the treated water. The revised plant came online in September 2010 Further up the mountainside is the Welsh Highland Railway, which offers splendid views of the lake from the south. Road and railway both run from Caernarfon to Beddgelert and then through the Aberglaslyn Pass to Porthmadog. The railway comes from Caernarfon and as it approaches the lake veers left from the Castell Cidwm rock face through a hand-carved rock cutting and under a small bridge before heading up the east side of the lake towards Snowdon Ranger railway station and later Rhyd Ddu railway station at the start of the Rhyd Ddu path to the summit of Snowdon. Rail and road run side by side for over half a mile to the summit of the mountain pass at Pitt's Head where the road passes over the railway before descending steeply through Nant Colwyn to Beddgelert. Pitt's Head is also the starting point of the old 'Beddgelert' route of the Rhyd Ddu path to Snowdon. Midway along the eastern shore of the lake is the starting point of the easier but less sensational Snowdon Ranger path to the summit of Snowdon. This route makes an excellent way down Snowdon as the view of the lake is magnificent whatever the weather. Since the Middle Ages the overland route from Caernarfon to Beddgelert via Llyn Cwellyn and then via the River Glaslyn and the Traeth Mawr to Cardigan Bay was often the preferred alternative to the long voyage round the Llŷn Peninsula.

Foel Gron is a peak on the Moel Eilio ridge of hills/mountains in Snowdonia, North Wales. This ridge is used as a hiker's route from Llanberis to the summit of Snowdon.

Rhyd-ddu (; Welsh: [ˌr̥iːdˈðiː]; lit. 'black ford') is a small village in Snowdonia, North Wales which is a starting point for walks up Snowdon (via the Rhyd Ddu Path), Moel Hebog, Yr Aran and the Nantlle Ridge. It lies on the A4085 between Beddgelert and Caernarfon, at its junction with the B4418 to Nantlle and Penygroes. Rhyd Ddu railway station is one of the stops on the Welsh Highland Railway between Caernarfon and Porthmadog. T. H. Parry-Williams, the poet, author and academic was born and raised at Rhyd-ddu. He twice won both the chair and the Crown at the National Eisteddfod, in 1912 and 1915.

The Welsh Highland Railway (WHR; Welsh: Rheilffordd Eryri) is a 25-mile (40.2 km) long, restored 1 ft 11+1⁄2 in (597 mm) narrow gauge heritage railway in the Welsh county of Gwynedd, operating from Caernarfon to Porthmadog, and passing through a number of popular tourist destinations including Beddgelert and the Aberglaslyn Pass. At Porthmadog it connects with the Ffestiniog Railway and to the short Welsh Highland Heritage Railway. In Porthmadog it uses the United Kingdom's only mixed gauge flat rail crossing. The restoration, which had the civil engineering mainly built by contractors and the track mainly built by volunteers, received a number of awards. Originally running from Dinas, near Caernarfon, to Porthmadog Harbour, the current line includes an additional section from Dinas to Caernarfon. The original line also had a branch to Bryngwyn and the slate quarries around Moel Tryfan, which has not been restored. (This branch forms a footpath "rail trail", the lower section of which has been resurfaced and supplied with heritage notice-boards.) There is also the 3⁄4-mile (1.2 km) long Welsh Highland Heritage Railway which runs from Porthmadog along the trackbed of the former Cambrian Railways exchange siding and connects to the WHR main line at Pen-y-Mount junction.

Rhyd Ddu is a station on the narrow gauge Welsh Highland Railway, which was built in 1881 as the North Wales Narrow Gauge Railways Moel Tryfan Undertaking to carry dressed slate to Dinas Junction on the LNWR. It has also previously been named both "Snowdon" and "South Snowdon". "Rhyd Ddu" is Welsh for "Black Ford".

Plas-y-Nant is an unstaffed halt on the narrow gauge Welsh Highland Railway.

Moel Eilio is a mountain in Snowdonia, North Wales, that is situated approximately 3 miles north-west of Snowdon itself. It has two subsidiary tops, Foel Gron and Foel Goch (Eilio). The average annual temperature of the mountain is around 6 degrees Celsius. During the winter season, some significant accumulations of snowfall is known to take place on Moel Eilio, due to its relatively flat, grassy slopes. A popular ascent starts from Llanberis and climbs by way of Bwlch y Groes and then the north ridge of the hill. Moel Eilio, Foel Gron, Foel Goch and Moel Cynghorion form a curved ridge tracking generally south-west towards Snowdon and can provide a less common route to ascend Snowdon.A small lake lies below the summit; Llyn Dwythwch.

Y Garn is a top of Mynydd Drws-y-Coed in Snowdonia, north Wales and is the easterly end of the Nantlle Ridge.It has steep north-facing cliffs, the summit area being the highest point on a broad rocky plateau. The summit plateau contains two large shelter cairns.

Moel Cynghorion (the Hill of the Councillors) is a mountain in Snowdonia, North Wales. It lies two miles north-west of Snowdon, and forms part of the Moel Eilio Horseshoe walk. The summit is situated on a wide plateau, marked by a pile of stones. The southern slopes are gentle, while the northern aspect is precipitous. The summit has close views of Clogwyn Du'r Arddu and Snowdon (Yr Wyddfa). Views from the summit can extend as far as Holyhead in Anglesey to nearby towns and villages in Gwynedd such as Caernarfon, Llanrug and Llanberis. On a clear day the Wicklow Mountains in Ireland can be seen across the Irish Sea, at a distance of approximately 80 miles.

Mynydd Drws-y-Coed is a peak on the Nantlle Ridge in Snowdonia, north Wales. It is located at the easterly end of the ridge, and is a subsidiary summit of Trum y Ddysgl. It has steep west-facing cliffs, the summit area being the highest point on a thin ridge.The west side is very rocky and airy, and some scrambling is needed to attain the summit. A good head for heights will also be needed on the exposed regions.

Pitt's Head railway station co-served the village of Rhyd-ddu, Gwynedd, Wales, from 1923 to 1936 on the Welsh Highland Railway.

Pitt's Head (Welsh: Carreg Collwyn) 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.
