A car is recommended for getting around Signal Hill and visiting nearby areas. Alternatively, there are ride-hailing services and public transport options available. The estimated travel time between the LAX airport and Signal Hill is 30-45 minutes, and the estimated cost of renting a car is around $40-60 per day.
If you have more time, consider taking a whale-watching excursion from Long Beach or visiting the Aquarium of the Pacific. Alternatively, if you have less time, prioritize the Hilltop Park for the stunning views and relaxation.
