While some attractions are walkable, the best way to get around Sierra Madre is by car. Renting a car in the area starts from $40 per day, although ride-sharing options are available. Some locations require additional parking fees. Keep in mind that traffic in LA can affect travel time, plan accordingly.
If you have more time, consider taking a day trip to the beach or visiting other local museums, such as the Norton Simon Museum or the Autry Museum of the American West. If you have less time, consider combining some attractions, such as spending the morning at the Sierra Madre Nature Trail and the afternoon at Bailey Canyon Park. Avoid peak traffic times to maximise the amount you can see and lower your stress levels.
