U.S. 101 is the main route into Santa Barbara. If you're staying in town, a car is handy but not essential; the beaches and downtown are easily explored by bicycle or on foot. Visit the Santa Barbara Car Free website for bike-route and walking-tour maps, suggestions for car-free vacations, and transportation discounts.
Santa Barbara Metropolitan Transit District's Line 22 bus serves major tourist sights. Several bus lines connect with the very convenient electric shuttles that cruise the downtown and waterfront every 10 to 15 minutes (50¢ each way).
Santa Barbara Trolley Co. operates a motorized San Francisco–style cable car that loops past major hotels, shopping areas, and attractions from 10 to 4. Get off whenever you like, and pick up another trolley (they come every hour) when you're ready to move on. The fare is $19 for the day.
