Baldwin Street, in Dunedin, New Zealand is located in the residential suburb of North East Valley, 3.5 kilometres (2.2 mi) northeast of Dunedin's central business district. Guinness World Records calls it the steepest street in the world, meaning no street gains more altitude in 10 horizontal meters, measured along the street's centerline.
A straight street a little under 350 metres (1,150 ft) long, Baldwin Street runs east from the valley of the Lindsay Creek up the side of Signal Hill towards Opoho, rising from 30 m (98 ft) above sea level at its junction with North Road to 100 m (330 ft) above sea level at the top, an average slope of slightly more than 1:5. The lower reaches are only moderately steep, and the surface is asphalt, but the upper reaches are steeper and surfaced in concrete (200 m or 660 ft long) for ease of maintenance (bitumen—in either chip seal or asphalt—would flow down the slope on a warm day) and for safety in Dunedin's frosty winters.
The 161.2-metre-long (529 ft) top section climbs 47.2 metres (155 ft) vertically, an average gradient of 1:3.41. At its maximum, about 70 metres (230 ft) from the top, the slope of Baldwin Street is about 1:2.86 (19° or 35%): in 2.86 metres (9.4 ft) travelled horizontally, the elevation changes by 1 metre (3.3 ft).
The street's steepness was unintentional. As with many other parts of early Dunedin, and indeed New Zealand, streets were laid out in a grid pattern with no consideration for the terrain, usually by planners in London. In the case of Baldwin Street (and much of the Dunedin street plan), the layout was surveyed by Charles Kettle in the mid-19th century. The street is named after William Baldwin, an Otago Provincial Councillor and newspaper founder, who subdivided the area.
For cars it is a dead-end street, but Baldwin Street is linked across the top by Buchanan Street, a footpath following an otherwise unformed (i.e. unpaved) road linking it with Calder Avenue and Arnold Street, which are unformed in their upper reaches where Baldwin is steepest. The streets running parallel to Baldwin are all steep: Arnold Street (1:3.6), Dalmeny Street (1:3.7), and Calder Avenue (1:5.4).
In 1987 Baldwin Street was recognised as the world's steepest street by the Guinness Book of Records following a two-year campaign by the broadcaster Jim Mora. At the time, Baldwin Street topped two competing streets in San Francisco, which hitherto had held the title of being the steepest streets in the world.
On 16 July 2019 Baldwin Street lost its title of World's Steepest Street to Ffordd Pen Llech, with Baldwin Street being at a gradient of 35%, and Ffordd Pen Llech being at a gradient of 37.45%. Otago Chamber of Commerce chief executive Dougal McGowan remarked that it could lead to a drop in visitor numbers to Baldwin Street but added that it could be a "blessing in disguise for some residents fed up with crowds of visitors, trampled gardens and bad driving decisions on the street." Mayor of Dunedin Dave Cull said that the Dunedin City Council could consider altering the signage wording from the world's steepest street to the southern hemisphere's steepest street.
On 8 April 2020, after an extensive review of an appeal to return the title to Baldwin Street filed by several Dunedin residents led by surveyor Toby Stoff, it was decided that the steepness of the street must be based on the central axis, which meant that Ffordd Pen Llech had a gradient of 28.6% compared to Baldwin Street's 34.8%. This meant that the title of Steepest Street was returned to Baldwin Street.
The street is the venue for an annual event in Dunedin, the Baldwin Street Gutbuster. Every summer since 1988 this exercise in fitness and balance involves athletes running from the base of the street to the top and back down again. The event attracts several hundred competitors annually and the race record is 1:56.
In March 2001, a 19-year-old University of Otago student was killed when she and another student attempted to travel down the street inside a wheelie bin. The bin collided with a parked trailer, killing her instantly, and causing serious head injuries for the other student.
Since 2002, a further charity event has been held annually in July, which involves the rolling of over 30,000 Jaffas (spherical confectionery-coated chocolate confectionery). Each Jaffa is sponsored by one person, with prizes to the winner and funds raised going to charity. This event follows a tradition started in 1998, when 2,000 tennis balls were released in a sponsored event raising money for Habitat for Humanity.
On 26 January 2018, 11-year-old Harry Willis raised over $11,000 NZD for the Ronald McDonald House in Christchurch by ascending the street on a pogo stick. The climb took around ten minutes. Willis's effort has since been commemorated with a plaque at the top of the street.
On 10 January 2019, a man rode a Lime scooter down Baldwin St, the same day that the scooters had been introduced to Dunedin and a week after Dunedin's mayor, Dave Cull, had said he was relying "on people's common sense" not to take the scooters down the world's steepest street.
Other steep streets include:
- A street in Stilfs in South Tyrol (Italy) has a 40% gradient as indicated by the street sign. This is a residential street and a cul-de-sac.
- The Côte St-Ange in Chicoutimi, Quebec, Canada with an alleged 33% gradient (about 18°). However this again appears to be down to confusion between slope angle and percentage grade; the street is signed as having an 18% grade.
- Canton Avenue, in Pittsburgh, Pennsylvania, United States; it is officially measured to be a 37% grade. However, that angle of 37% only extends about 6.5 metres (21 ft), whereas Baldwin Street's steepest part stretches considerably farther.
- Eldred Street in Los Angeles, United States; one of three streets in Los Angeles between 32% and 33.3%.
- Filbert and 22nd Streets in San Francisco, California, United States each have 31 to 31.5% (17°) for 60 to 70 metres (200 to 230 ft). Several short pieces of San Francisco streets are steeper, including a 9-metre section of Bradford street paved in 2010 that averages 39–40% grade.
- Waipio Valley Road (island of Hawaii. As measured by Stephen Von Worley, the road has long sections that measure 30% with peak gradients much higher; some areas up to 39%. This is a paved public road but it is not a residential street and is open only to 4 wheel drive vehicles. ) on the
- Ffordd Pen Llech in Harlech, Wales has a reported slope of 36.6% (rounded to 40% on the warning sign).
- Muro di Sormano (Wall of Sormano) is a well-known cycling stage in Northern Italy, with a maximum gradient of 27%, included in the Giro di Lombardia cycling race.
Many streets in the west of England and in Wales have reported slopes of 33% and higher. Vale Street in Bristol is often also reported as the steepest street in Britain (21.81°/40.02%) and hence may have a slope even steeper than 36.6%. However, these roads are mostly shorter roads than those listed above, with far more frequent turns as opposed to the straight path of Baldwin.

That's measured in a straight line along the pavement; if you measure along the sort-of-centerline the grade is 39.6%.
