Sacramento is fairly easy to navigate due to the numbered and lettered streets, especially in the central district which is laid out in a grid. Numbered streets run north and south while lettered streets run east and west. South of the city center bounded by Broadway, Front Street, and Alhambra Boulevard, the streets are named "Avenue" when the lettered streets run out.
On foot
Historic Old Sacramento, the Riverfront, and the California State Railroad Museum are all within an easy five minute walk of the train station. The Capitol is a 15 minute walk from Old Sacramento.
By public transport
Regional Transit (http://www.sacrt.com) is the major provider of bus and light-rail service in Sacramento with connections to other inter-urban buses and the surrounding area.
By car
For nearly all other getting around, you will want a car.
