Valley (Welsh: Y Fali) is a village, community, and former electoral ward near Holyhead on the west coast of Anglesey, North Wales. The population during the 2001 census was 2,413, decreasing to 2,361 at the 2011 census.

Valley Station signal box is a Grade II listed, 2-story, timber built signal box located near the railway station in Valley, Anglesey. Located directly north west of the level crossing on the B4545 road, the Signal Box is thought to have been built in the middle of the 19th century as one of 15 new huts built along the Chester and Holyhead Railway. Clad with horizontal tongue and groove panelling, with large sash windows and a slate roof. The interior of the signal box remain unchanged and still features the original lever frames.

Valley railway station (Welsh: Gorsaf reilffordd y Dyffryn) is a railway station that serves the village of Valley in Anglesey, Wales. It is the last station before the western terminus of the North Wales Coast Line at Holyhead. It also serves the nearby RAF base and Anglesey Airport.

St Mary's Church was a Church in Wales parish church in Llanfair-yn-Neubwll, Anglesey, Wales. The current building was constructed in the 14th century, possibly on the site of a 12th-century church. It was restored in 1857. The church was deconsecrated in the 1970s and is a Grade II-listed building.

The Stanley Embankment (known locally as the Cob) is a railway, road and cycleway embankment that crosses the Cymyran Strait in Wales, connecting the Island of Anglesey and Holy Island. It carries both the North Wales Coast Line for trains, which runs from Crewe to Holyhead and the A5 road between London and Holyhead. The embankment was designed by, and its construction overseen by, Thomas Telford and was named after the Stanley family who were significant benefactors to the area.Prior to its construction the fastest route to Holyhead from the island's mainland was via the old stone bridge at Four Mile Bridge (Welsh: Pontrhydybont/Pont-rhydbont/Pontrhypont). When the A5 road was being constructed between London and the Port of Holyhead a more direct route was needed. Construction started in 1822 and completed a year later and is a total of 3⁄4 mile (1.2 km) long. It is significantly wider at the base (35 metres) than at the top (10 metres). The embankment to Holy Island was constructed using rock and materials excavated from a site on the Anglesey side. A workers’ hamlet grew up around the artificially-created depression, which was nicknamed “the valley”. After work ended, the settlement remained developing into a medium-sized village known as Valley. A year after opening, the embankment was partly damaged in a storm in 1824.In the 1840s, the embankment was chosen to carry the North Wales Coast Line to the Port of Holyhead (rather than build an entirely new crossing). Work to significantly widen the structure was completed in 1848. To allay concerns that passing trains might startle horse drawn traffic using the embankment, a tall stone dividing wall was built between the road and the railway.The embankment remained the only major crossing between Holy Island and Anglesey for more than 175 years. In 2001 it was superseded by a new wider embankment, which was built as part of the final section of the A55 North Wales Expressway. The section completely bypassed Valley and the old A5 at this point. The new crossing, which carries the modern A55 dual carriageway, was built parallel to the Stanley Embankment, following its north–south alignment.

Four Mile Bridge (Welsh: Pontrhydybont / Pont-rhydbont / Pontrhypont) is a village spanning both sides of the Cymyran Strait in Wales, connecting Holy Island with Anglesey, and is approximately three miles (5 km) southeast of Holyhead. The village is quite small and is split between two communities on the two islands. The larger portion of the village is the principal settlement in the community of Rhoscolyn which recorded a population of 542 in the 2011 census. A small part of the village is in the community of Valley, Anglesey. The village is about one mile (1.5 km) from Valley railway station, and is on the Isle of Anglesey Coastal Path. The village has a hairdressers and a pub named "The Anchorage".

Cymyran Strait (Welsh: Culfor Cymyran) is a strait that runs from Beddmanarch Bay in the north to Cymyran Bay in the south between the islands of Anglesey (Ynys Môn) and Holy Island (Ynys Cybi). At either end it opens up into the Irish Sea. The strait was first crossed with a permanent land-link by the Four Mile Bridge by the latest date of 1530. It was later crossed by the A5 London to Holyhead Road at Stanley Embankment in 1823, the North Wales Coast Line using the same embankment in 1848, and finally the separate A55 expressway in 2001. The area specifically between the Stanley Embankment and the Four Mile Bridge is often referred to as the Inland Sea (Y Lasinwen) and is almost a lagoon. The only settlement on the shores of the strait is Four Mile Bridge itself, although the town of Holyhead and the villages of Valley and Trearddur are close by.

Beddmanarch–Cymyran is a site of special scientific interest (SSSI) on the Welsh island of Anglesey extending to just over 900 hectares (2,200 acres), and centred on the Cymyran Strait. It was first notified in 1961 for its coastal botanical and ornithological interest. The site is also a marine protected area as it includes intertidal areas and contains marine components.

Aber Alaw (Welsh: "Mouth of the Alaw" ) is at the mouth of the Afon Alaw on Anglesey, in North Wales. It is located just north of Valley and south west of Llanfachraeth. According to the Mabinogion, it is here that Queen Branwen died of grief after escaping the destruction of Ireland. She and the seven survivors of Prydein (Britain) landed at Talebolyon, and upon seeing the coasts of both Ireland and Prydein, she died of a broken heart, blaming herself for the havoc. At Llanddeusant, Anglesey on the banks of the Alaw can be found the cairn called Bedd Branwen, her supposed grave. Now in ruins, it still has one standing stone. It was dug up in 1800, and again in the 1960s by Frances Lynch, who found several urns with human ashes.

The Afon Alaw (English: River Alaw) is a river on Anglesey (Welsh: Ynys Môn) in Wales which rises near Llanerch-y-medd and flows northwards into the reservoir of Llyn Alaw. Below the dam it then flows southwestwards to the island's west coast near Llanfachraeth. Its lower reaches, west of the A5025 road, are tidal.

Ynys Benlas is a small islet situated in the Inland Sea (Welsh: Y Lasinwen), part of the Cymyran Strait between Anglesey and Holy Island. It measures approximately 65 metres (east-west) by 35 metres (north-south) at low tide and covers about 0.2 hectares. Its name translates from the Welsh for "blue top island", which is thought to derive from the fact that bluebells apparently flourished on it. Late nineteenth century Ordnance survey maps refer to the islet as Ynys Henlas, which translates as "old blue island" According to the Archaeological Journal (1844), the islet (referred to as Ben Las in the Journal) may have been an ancient signal hill.

Llanfair-yn-Neubwll is a village and community on the Isle of Anglesey in the north west of Wales. The community includes the villages of Llanfihangel yn Nhowyn and Caergeiliog, and had a population of 1,688, increasing to 1,874 at the 2011 census. The community is heavily connected to the nearby Royal Air Force airfield, RAF Valley, established on Tywyn Trewan during the Second World War, and still in use. Due to the airfield, Llanfair-yn-Neubwll is one of the most anglicised of the communities on Anglesey.Llanfair-yn-Neubwll lies on the western coast of Anglesey, looking out towards Holy Island. Notable geographic features of the area include the offshore rocks of Ynys Feirig and the eight lakes known as Ardal y Llynnoedd ("Lake District"). Many of the lakes are included in the Valley Wetlands RSPB reserve. The community is served by the nearby railway station at Valley on the North Wales Coast Line. This provides connections to Holyhead, Wrexham, Chester, Crewe and Birmingham.
