Llyn Cerrig Bach is a small lake located between Rhosneigr and Valley in the west of Anglesey, Wales. Whilst it is not one of the largest lakes on the island (around 1.8 acres), its claim to fame is the group of over 150 Iron Age metal objects discovered there in 1942, apparently placed in the lake as votive offerings. These finds are considered to be one of the most important collections of La Tène style metalwork, or Early Celtic art discovered in the British Isles, and the most important in Wales.

St Mihangel's Church in the village of Llanfihangel yn Nhowyn is a former parish church now used as the chapel for RAF Valley in Anglesey, north Wales. The date of the first church on the site is uncertain, but in 1862 the then-existing church was rebuilt. St Mihangel's became the chapel for the nearby Royal Air Force base in 1998, after the Church in Wales had ceased using it for services. It was then extended by dismantling and reassembling another Anglesey church, St Enghenedl's, at the west end of the building. The church is a Grade II listed building, a national designation given to "buildings of special interest, which warrant every effort being made to preserve them", in particular because it is regarded as "a good example of a mid 19th-century church". The church contains some stained-glass windows commemorating the work carried out at RAF Valley, including the RAF Search and Rescue units based there.

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.

The village was the site of the historic St Enghenedl's Church, demolished in 1988.

St Enghenedl's Church, Llanynghenedl, is a former parish church in Anglesey, north Wales, dedicated to the son of a 6th-century King of Powys. According to the 19th-century antiquarian Angharad Llwyd, the first church in Llanynghenedl was erected in about 620. A new church was erected in 1862, replacing a building that the 19th-century clergyman and antiquarian Harry Longueville Jones noted as dating in part from the late 13th or early 14th century, based on the decorations on the south doorway. The church later fell into disuse as a result of the growth of the nearby village of Valley and the church there. In 1988, St Enghenedl's was dismantled and re-erected as an extension to St Mihangel's, Llanfihangel yn Nhowyn, so that St Mihangel's could serve as the church for RAF Valley. The former churchyard of St Enghenedl's is still visible but is now overgrown.(The churchyard is being cared for and no longer overgrown 2020 update)

Llyn Traffwll is a 91 acre natural lake located, in Anglesey, Wales. Located midway between the villages of Rhosneigr and Valley it lies less than a kilometre south of the A55 North Wales Expressway. It is the largest natural lake on the island with Llyn Alaw and Llyn Cefni both being reservoirs. Along with the surrounding smaller lakes it is a Site of Special Scientific Interest and is adjacent to the Valley Wetlands RSPB site. Formerly (starting in 1866) the lake was used to supply water to Holyhead by the Holyhead Water Company, and to aid water management a small dam was built which still exists.In late 2019 it was reported that a 300 acre Photovoltaic power station called Parc Solar Traffwl was planned to be constructed near the lake. The Welsh language novel Madam Wen, Arwes yr Ogof, written by William David Owen, is set by the lake.
