To explore Diamond Bar, it is best to rent a car or use ride-sharing apps like Uber or Lyft. A car allows you to move around freely with ease and explore all the stunning sites the city has to offer. The average cost of renting a car is $25 to $50 per day, and Uber or Lyft rides for the entire trip will approximately cost $100.
If you have extra time, you can visit the Japanese Garden or the LA County Museum of Art. For nature enthusiasts, you can swap the Diamond Bar Center for the Schabarum Regional Park, where you can bike or hike its challenging terrains. If you have less time, you can choose only a few sites to focus on to ensure that you enjoy your trip without rushing.
