To make the most of your trip to Bradbury, consider renting a car as public transportation options can be limited. The cost for renting a mid-sized car for five days ranges from $200 to $300. It is important to note that traffic can be heavy in Los Angeles, so you may need to factor that into your travel time.
If you have more time, consider visiting other attractions such as Six Flags Magic Mountain and Getty Center Museum. If you have less time, you can skip the Los Angeles County Arboretum and Botanic Garden as it is more nature-based and may not be suitable for everyone.
The closest airport to Bradbury is the Ontario International Airport (ONT) which is approximately 25 miles from the city center. The Los Angeles International Airport (LAX) and the John Wayne Airport (SNA) are also options, but they are located further away.
