Alhambra is a small city, and most locations on this itinerary are within walking distance. However, if you prefer driving, parking is easily available at all locations. If you're coming from outside of Alhambra, ride-hailing services like Uber and Lyft are readily available.
If you have more time, consider visiting the Garfield Theatre or the Vincent Price Art Museum. If you have less time, you can skip the Alhambra Park and the farmers market and head straight to The Huntington Library. Don't forget to bring comfortable shoes and a camera to capture all the amazing sights.
