This move is part of an effort to preserve Welsh cultural heritage and comes after a previous decision to use Welsh names, Yr Wyddfa and Eryri, instead of the English names Snowdon and Snowdonia, for the park itself.
Some lakes in the park, such as Llyn Tegid (Lake Bala) and Llyn Bochlwyd (Lake Australia), were known by both Welsh and English names. However, the park authority has now voted to use only the Welsh names. The decision was made in collaboration with Cardiff University's School of Welsh and the Welsh Language Commissioner.
The standardization focuses on both the Welsh spellings and the historic and cultural significance of the names. For instance, Llyn Bochlwyd's Welsh name refers to a legend about a grey stag, while its English name, Lake Australia, was derived from its outline resembling the shape of Australia.
The initiative aims to protect these historic names for future generations and to celebrate the richness of local dialects and folklore. The park authority plans to update maps and other materials to reflect these changes and will next focus on standardizing the names of waterfalls and mountains in the park.
