It is best to rent a car to explore Torrance as it is a spacious city that is not pedestrian-friendly. You can rent a car for around $50 - $100 a day, depending on when and where you book. Uber and Lyft services are also available in the city center, and public transportation is provided by the Torrance Transit. Keep in mind that the Torrance Transit Bus Service operates on a fixed schedule, so make sure to check the schedules.
If you have more time, you can visit the Redondo Beach or the Torrance Art Museum. If you have less time, you can skip any location or go to Del Amo Fashion Center if you are a shopping enthusiast. Remember to stay hydrated during summer days and bring sunscreen as the weather can get hot. Parking can be limited at certain locations, so plan ahead and arrive early.
