Residents claim street in town in Wales is steeper than Dunedin's Baldwin Street

Could Dunedin's Baldwin Street lose its claim to fame as the world's steepest street?

Baldwin Street has a gradient of 35 per cent at its steepest, but residents living in a small seaside town in Harlech, Wales, say one of their streets could take the title, the BBC reports.

Locals say they hope Ffordd Pen Llech can topple the Dunedin's street's record in the Guinness World Records - by one per cent.

"I'm pretty hopeful for sure. I would hope that they [Guinness World Records] would come and at least assess it, it would be nice if they'd come and check it out," Sarah Badhan, who runs a Harlech community page on Facebook, said.

"I lived away for a number of years and I used to proudly tell people about living in the town with what I believed to be the steepest hill in Britain. It's something we're all pretty proud of."
