Wales' tallest mountain will continue to be referred to solely by its Welsh name by its local national park authority after the move was deemed to be a success.
Snowdonia National Park Authority voted to use Yr Wyddfa, rather than Snowdon, and Eryri, rather than Snowdonia, in all official communication in November 2022.
Surveys from the summer found strong support for the move from locals and visitors, the authority said.
But there were also concerns over pronunciation and some visitors being "unaware of the longstanding Welsh names and may mistakenly believe they are new".
