Baldwin Street, according to the Guinness Book of Records, is the steepest street in the world. Its gradient is 1 in 2.9.

The first time I saw Baldwin street was a magical night. We walked the roads around midnight under a full moon, every street we passed was steeper than the last and each one was the steepest I'd seen in my life. The view from up those roads is beautiful, you can see the rolling hills of the whole city twinkle in the distance. I first saw Baldwin street from the top, we snuck down some private road, saw a hedgehog for the first time, and made it to this insane street. It's truly a monument of mans arrogance, I'm not sure there's words to describe it, but it's far steeper than I ever imagined.
