What counts as the world’s steepest street?

Tom Scott | December 11, 2025



Baldwin Street in Dunedin, New Zealand, has the Guinness World Record for “steepest paved road over a continuous distance of more than ten metres”. Which is enough to bring in quite a few tourists. What’s the history? And what counts as “steepest street”?

Thanks to Mayor Dave Cull and to Gary Blackman. You can see some of Gary Blackman’s photography in Te Papa’s collection: https://collections.tepapa.govt.nz/agent/222

And an interview with him: https://www.odt.co.nz/entertainment/arts/blackman-still-finding-out-what-camera-will-take

Updates:

In November 2022, Gary Blackman passed away: his obituary, and many of his photographs, can be found here. https://blog.tepapa.govt.nz/2022/12/02/gary-blackman-photographer-1929-2022/

In 2019, the Welsh street took the record: https://www.bbc.com/news/uk-wales-48992331 — but in April 2020, the New Zealand street appealed and took the record back: https://www.bbc.co.uk/news/uk-wales-52215151

    I had a technical hitch on the interview with Gary Blackman, and I've tried to recover the footage as best I can. That's an embarrassing mistake when filming a photographer! There are also links in the description to some of his photographs, and an interview with him. [Update: in November 2022, Gary Blackman unfortunately passed away. You can now also find a link to his obituary in the description, and it's worth reading.]

    I think this is kind of bs had a trip to Houghton and Hancock in upper Peninsula of Michigan, US and they got steeper streets than this. I think the name of one of them was Montezuma in houghton I think. At least one of them has gotta be like 45°.

    There are lots of places in east Tennessee that have roads like that. Hell even where I grew up, Castlewood Drive in Franklin TN has a brief slope that is as steep as this. Lots of fun to slide down on the snow days.

    I would like to nominate Brown Avenue in Neepawa, Manitoba, Canada. Specifically the block between Mill Street and Davidson Street. I haven't done any measurements but it appears to be steeper than the street in this video. And I think longer than 10 meters although I'm not certain.
