This picturesque stretch of Lombard Street has eight tight turns on a single block. They twist at very acute angles, making for very slow going if you are in a car. Although, oddly enough, cars were the reason for designing the street this way back in 1922. The idea was that this design would make it easier for them to negotiate the steep 16% grade. The drive is usually bumper-to-bumper and in the summertime, there is almost always a line of cars waiting to take the drive down. That being said, going for a stroll along this landmark is a good option, especially when the hydrangeas along the sidewalk are in bloom.
