If you have more time, consider visiting other attractions in the area, such as the Getty Villa Museum or the Zuma Beach. If you have less time, skip the Malibu Speedzone and spend more time at the Malibu Creek State Park or the Topanga State Park. Also, be prepared with sunscreen and plenty of water during outdoor activities.
