To get there, follow the one-way north, staying in the right lane. Keep going up the road, and you'll eventually get to Baldwin St., the steepest street in the world.
It's a good idea to walk up the whole street, because then you can actually feel how steep the slope really is, and the views from the top are stunning. There's a seat to reat your aching legs at the top, but unfortunately, the drinking fountain doesn't work.
The houses on the street are built up on one side, and it's funny to turn your head so you're looking at them at a parallel with the road. It looks as though the houses are built at a weird angle and about to fall over. It's possible to drive up (it is a road) if you're not able to walk.
