Trip Plan
For this 12-hour drive, splitting it over 2 days is highly recommended, with 3 planned stops to help break up the journey.

Keep an eye on your fuel gauge, as the longest stretch without a break is over 225 miles. It's wise to budget for the $147 fuel cost and factor in rest stops to stay alert.
Morning Departure
Start early — leave by 6-7 AM to arrive at a reasonable hour.
Evening Departure

This is the best place for your longest stop, a real meal, and a full fuel check.
Overnight split
Day 1 wrap after about 320 miles or 5h 52m

Before You Leave
+

Seasonal Notes
Summer travel usually means heavier construction, hotter rest stops, and busier weekend traffic around major cities.
Winter travel shortens daylight, so a route that looks manageable on paper can feel much longer after dark.
Holiday weekends tend to make both departure and arrival windows slower than the raw route time suggests.
For long drives, weather on day two can matter just as much as conditions at departure, so check the whole travel window rather than only the first day.
Time zone
Same local time
Origin and destination are on the same clock, so arrival timing is easier to judge at a glance.
Temperature spread
7 degrees cooler at arrival
A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.
Road read
12h 22m on the road
This is long enough that the arrival forecast matters almost as much as departure conditions. Recheck both ends before you roll.

About the Cities
Starting in Los Angeles, CA
Full guide →“Tinseltown” · Founded 1781
Frank Lloyd Wright is said to have quipped, "Tip the world over on its side and everything loose will land in Los Angeles," a quote that has since been repeated both by those who love and hate L.A. The "City of Angels" is home to people who hail from all parts of the globe and an important center of culture, business, media, and international trade. However, it's most famous for being a major center of the world's television, motion picture, and music industry, which forms the base of the city's status and lures visitors for its show business history and celebrity culture. Visitors are also drawn to Los Angeles for its Mediterranean climate and numerous beaches, which gave birth to California's famed surf culture.

It helps. This route has a higher-than-average number of complex decision points, which get harder in the dark. If the last hour of the trip is on surface roads or mountain grades, aim to arrive at Humboldt Hill, CA before sunset when you can. Check the Trip Plan for departure windows that land you in daylight.
Only with planning. This is a long drive for kids — consider splitting it into two days rather than pushing through. Plan at least 3 meaningful breaks. Dedicated rest areas are limited, so plan gas or food stops as your bathroom breaks.
