To get around Azusa, it's best to rent a car, especially since many of the destinations are far apart. You may also use taxi or ride-sharing services like Uber or Lyft. A rental car starts at around $30-40 per day, plus gas. Gas prices are relatively low in California, with an average of $3.50 per gallon. Keep in mind that traffic can be heavy during rush hour in the mornings and afternoons.
If you have more time, consider visiting the City of Hope National Medical Center or the Azusa Pacific University. If you have less time, you might skip some of the museums and spend more time outdoors. Also, don't forget to pack sunscreen, water, and comfortable shoes for hiking and walking. Lastly, have some cash on hand as some vendors at the Pomona Antique Mart are cash-only.
