Eryri

Eryri, known in English as Snowdonia, is a mountainous region in north-west Wales. Its Welsh name is used locally to refer to the same area that is administered as Snowdonia National Park. The park lies mainly in Gwynedd and comprises rugged mountains, glacial valleys, and lakes, including the peak Yr Wyddfa (Snowdon), at 1,085 metres, the highest point in Wales and England. The landscape was shaped by glaciation during the last Ice Age and supports a range of habitats from heath to broadleaved woodlands.

Snowdonia National Park was established in 1951 and covers a large area of roughly 2,130 square kilometres. The park is managed by the Snowdonia National Park Authority in cooperation with local authorities and communities, with an emphasis on conserving the landscape while promoting sustainable tourism and outdoor recreation.

The area is a major destination for walkers, climbers, and outdoor enthusiasts, and includes notable features such as Snowdon Mountain Railway and towns and villages like Llanberis, Betws-y-Coed, and Beddgelert. The Welsh language is strongly represented in the region, and Welsh place names appear prominently in signage and local culture.

Historically, the region has an industrial heritage, most notably slate quarrying around Blaenau Ffestiniog, with remnants visible in settlements and landscapes. Today, tourism, outdoor recreation, and heritage conservation are the principal economic activities in Eryri.
