Getting around South El Monte is best done by car. The city isn't very walkable, and public transport is limited. Rental cars are available at the Los Angeles International Airport (LAX). The average car rental costs around $35-50 per day, but prices may vary depending on the season and availability. Uber and Lyft are also available in the city, but costs can add up quickly, so it's best to reserve them only for short rides.
If you have more time, consider visiting the Watts Towers in Los Angeles, which is an excellent opportunity to see a unique collection of sculptural art. If you have less time, adjust the itinerary by skipping nonessential locations. Also, make sure to check the hours of your selected destinations as some may operate under unique schedules or be temporarily closed, especially during holidays or renovations.
