Wales’ highest mountain will be referred to by its Welsh name, rather than the English translation, park authorities have agreed.
Snowdonia National Park Authority voted to use Yr Wyddfa and Eryri rather than Snowdon and Snowdonia.
It said it was spurred to “decisive action” after 5,000 people signed a petition calling for the change.
Yr Wyddfa stands at 3,560ft (1,085m) and attracts about 400,000 walkers a year.
Naomi Jones, the park’s head of cultural heritage, said Welsh place names were part of Eryri’s “special qualities”.
