While Sierra Madre is a small, walkable town, it's best to rent a car to explore the surroundings. Taxi and ridesharing apps are also available, but may be more expensive. If you're flying in, the best airport to arrive at is Burbank Bob Hope Airport which is approximately 25 minutes drive to Sierra Madre.
Total Travel Cost (including airport transfer): $50
If you have more time, consider visiting Sierra Madre Villa, Heasley Homestead Park, or Snow Creek Ranch. For more physically challenging activities, Mount Wilson Trail Park and Mount Wilson Observatory are a must-try. If you have less time, you may opt to visit either the Sierra Madre Playhouse or Downtown Sierra Madre and extend your visit for more than a day.
