The Welsh national park formerly known in English as Snowdonia was renamed Eryri in official use in 2022.
In November 2022, the Snowdonia National Park Authority voted to prioritise the Welsh names Eryri for the park and Yr Wyddfa for Wales’s highest mountain. The decision applied to the authority’s communications and marked a gradual move away from Snowdonia and Snowdon, rather than erasing the older English names from everyday speech or all statutory contexts.
Eryri covers roughly 823 square miles of north-west Wales and includes rugged mountains, glacial valleys, lakes, forests and a substantial coastline. Its highest summit, Yr Wyddfa, reaches 1,085 metres and is the highest point in Wales and England. The name change is therefore about the park’s identity and language policy, not the creation of a new protected area.
A common mix-up is treating Eryri as the name of the mountain. Eryri refers to the wider national park; Yr Wyddfa is the Welsh name of the summit commonly called Snowdon.
