Parking spaces are limited in Nevada City and backing into some of them with hilly conditions can be difficult. There are nine parking lots in town and several hundred on street parking lots of which only six are reasonable choices for tourists wanting to get out and see the City. A link showing all is provided below;
Two areas of town that will sometimes have parking spaces when others fill up are the Commerical Street parking lot (Map Location 3) and the Nevada City Veterans Hall but is limited and pretty far out of the way. The former offers parking for two hours for 25 cents and the latter is free. Bring your quarters!
From San Francisco take I-80 to Vallejo/Sacramento; after about 70 miles merge onto I-80E and take East Ramp towards Reno; travel about 35 miles and take exit CA-49 to Grass Valley/Placerville; turn left onto CA-193; after 28 miles CA-139 becomes CA-49 -> turn left; after aproximatly 27 miles take exit Broad Street.

You'd better have a car in Nevada County....!
One you're in town, walking is the best way to get around. Just like this couple is doing, walking down the aisle.
