It's best to rent a car when visiting Azusa as it's the easiest way to get around. Rates vary depending on the type of car you rent and the duration of your trip. Expect to spend around $300-$500 on car rental fees for the week. Travel times range from 30-60 minutes depending on your destination, and distances range from 5 miles for city destinations to 150 miles for day trips.
If you have more time, consider visiting some of the other parks such as Yosemite National Park and Sequoia National Park. However, if you have a tight schedule, it's recommended to skip Palm Springs and focus on Azusa, Los Angeles and San Gabriel Mountains.
The nearest airport is Ontario International Airport (ONT), which is in Ontario, California, located about 25 miles west of Azusa. Los Angeles International Airport (LAX) is also an option, which is about an hour drive to Azusa.
