Tips for This Route
Split the drive into two days
With four stops and over eight hours of driving, consider an overnight in the Bakersfield or Santa Clarita area. A rested family handles the LA freeway traffic through Sylmar and the I-5 corridor far better than a tired one.
Plan for LA traffic
The segment through the San Fernando Valley near Sylmar can add significant time if you hit rush hour. Aim to pass through the LA metro area between 10 AM and 2 PM or after 7 PM to minimize delays on I-5 and I-405.
Fuel up at Kettleman City
Kettleman City has 12 gas stations and is the last major fuel hub before the long climb over the Grapevine. Topping off here saves you from paying premium prices at the smaller stations near Tejon Pass.
