visitors

The park authority said some visitors were "unaware of the longstanding Welsh names and may mistakenly believe they are new".

A park authority survey carried out over the summer found up to 65% of visitors to Yr Wyddfa viewed the changes as positive, while 10 to 15% said they were not in support.

There have been concerns about pronunciation and whether some visitors might be confused.

The national park authority said it would continue to use Yr Wyddfa and Eryri following a survey which found the majority of visitors viewed the change as positive.

"When I speak to visitors often they will be really enthusiastic about Welsh names because they come to Wales and they find the Welsh language and the culture a refreshing change," he said.
