While San Dimas is accessible by bus and train, having a car will make it easier to get around and explore the surrounding areas. Expect to spend around $15-$25 per day on gas for local trips, and $50-$75 per day for day trips to Los Angeles or nearby beach towns, depending on traffic.
If you have a few extra days, consider visiting the nearby cities of Pasadena or Glendora for unique shops and delicious food. If you have less time, prioritize the must-see attractions such as Raging Waters or the Los Angeles County Fair. Weather can be hot in San Dimas, so come prepared with sunscreen and plenty of water. Lastly, check for daily deals or seasonal discounts on attraction tickets or food items to save some money.
