It is recommended to rent a car to explore Rancho Palos Verdes, as public transportation is limited. Many of the points of interest are spread out and require driving. Car rentals in Los Angeles typically cost around $30-$50 per day. Keep in mind that the average travel time between points of interest is around 20-30 minutes.
If you have more time, consider visiting the nearby city of Long Beach, which offers beaches, museums, and restaurants. Alternatively, if you have less time, consider skipping some of the less popular points of interest and focusing on the ones that interest you the most. Keep in mind that some of the beaches close early, so check closing times before visiting.
