Outside the core of San Francisco, a rental car is close to required in California. The state is roughly 800 miles top to bottom, the national parks and the coast have no useful transit, and distances that look short on a map turn into real hours on the road. This guide covers what matters when you rent here: where to pick up, what it costs, the fees that catch people out, and the driving rules for mountains and desert that a rental counter will not warn you about. For the wider picture on moving around the state, see getting around California.
Where to Pick Up and Drop Off
Fly into the airport closest to where your trip starts rather than defaulting to one hub. Los Angeles International (LAX) and San Francisco International (SFO) have the largest fleets and the most competition, which usually means the best base rates. But their rental centers are off-site shuttle rides that add 20 to 40 minutes each way, and both airports pile on concession fees. Smaller airports like Burbank (BUR), Oakland (OAK), San Jose (SJC), and San Diego (SAN) are faster to get in and out of, and Palm Springs (PSP) or Fresno (FAT, the closest to Yosemite and Sequoia) can save you hours of driving depending on your route.
The single biggest money decision is one-way versus round-trip. Picking up at SFO and dropping at LAX, which is the natural direction for a Highway 1 road trip, triggers a one-way drop fee that commonly runs $100 to $300 depending on the company and season. Sometimes it is waived within California, sometimes it is not, so price both a one-way and a loop before you book. If the loop only adds a few hours of driving back, it can be cheaper than the drop fee.
One detail that saves real money on the SFO end: you can skip the airport entirely. SFO’s rental center adds a $10-plus per-day customer facility charge on top of the concession fees, so if San Francisco is your start and end point, picking up from a downtown city branch often comes in cheaper even after the BART or rideshare to get there. The same logic applies at LAX, where the off-airport shuttle circus eats time you could spend driving.
What It Really Costs
Base rates swing hard by season. Summer and holiday weeks are the expensive stretch, and a mid-size car that rents for $45 a day in spring can run $90 or more in July. Book early for peak dates. Beyond the daily rate, budget for the extras that stack up:
- Airport concession and facility fees, often 10 to 12 percent on top of the base rate at LAX and SFO.
- Sales tax, which varies by location and lands roughly in the 8 to 10 percent range.
- A young-driver surcharge if anyone driving is under 25, usually $25 to $35 a day.
- Additional-driver fees, though many companies waive these for a spouse.
Gas is its own line item. California has the highest fuel prices in the country, frequently $1 to $1.50 a gallon above the national average, so a full tank costs more here than almost anywhere else. Never take the prepaid-fuel option unless you plan to return the car near empty, and always refuel yourself before drop-off to dodge the refueling surcharge, which can be double the pump price. Watch mileage terms too. Most standard rentals include unlimited miles within the state, which is what you want given the distances, but some prepaid discount rates and peer-to-peer listings cap the daily mileage and bill per mile over the limit, and on a 1,500-mile loop that adds up fast.
Insurance, Tolls, and the Fine Print
Before you buy the counter’s collision waiver, check two things you may already have. Many U.S. credit cards include rental collision coverage if you pay with that card and decline the rental company’s version, and your existing auto policy at home often extends to rentals. International visitors usually do need to buy coverage, since home policies rarely cross the border. The rental company’s full protection can add $30 to $60 a day, so this is worth sorting out before you land, not at the counter under pressure.
Tolls are mostly a Bay Area issue. The Golden Gate Bridge is cashless and bills by license plate, and several Bay bridges and a few express lanes charge electronically. Ask whether your rental includes a toll transponder and what the daily service fee is, because those fees can cost more than the tolls. Elsewhere in the state, tolls are rare.
Two more items: request any child seats when you book rather than at the counter, and if you want to cross into Mexico toward Tijuana or Baja, know that most California rental contracts prohibit it or require special insurance. Do not assume you can drive south of the border.
International visitors need a couple of documents sorted before the counter. Your home driver’s license is accepted in California if it is in English; if it is in another alphabet, bring an International Driving Permit alongside it. Most major companies set a minimum rental age of 21 and stack the under-25 surcharge on top, and nearly all require a physical credit card in the renter’s name for the security hold, which can run several hundred dollars beyond the rental cost until you return the car. Debit cards are often refused or trigger a credit check, so travel with a real credit card.
Electric Cars and Charging
Rental fleets in California carry a growing share of EVs, and companies like Hertz sometimes hand you one at no extra cost or even push them as upgrades. Before you accept, think about your route. An EV is fine for a city stay or a Bay Area loop where chargers are everywhere, but it changes how you plan a long drive. Tesla’s Supercharger network is dense along Interstate 5 and the coast, and third-party fast chargers from Electrify America and EVgo cover the main corridors, but the Eastern Sierra, Death Valley, and the far North Coast have real gaps. If you are running Highway 395 or crossing the desert, a gas car removes a planning headache. If you do take an EV, ask exactly how the company wants it returned, because return-charge policies vary and some bill a steep fee for bringing it back low, the same trap as the prepaid-fuel option on a gas car.
Driving the Mountains and the Desert
California’s terrain adds rules a flat-state driver never thinks about. In the Sierra, from roughly November through April, the California Highway Patrol can require tire chains or all-wheel drive with snow tires to reach Tahoe, Mammoth, and Yosemite’s higher roads. Not every rental company allows chains on their cars, and some ban them outright, so ask before you book if snow is on your itinerary and consider renting an AWD or 4WD vehicle for a winter mountain trip. Tioga Road across Yosemite and other high passes close entirely for winter, usually from around November into late May or June.
The desert is the opposite hazard. In Death Valley and Joshua Tree, summer heat can top 110 degrees, fuel ranges are long, and cell service disappears. Fill the tank before you enter, carry extra water, and do not push a small car up rough backcountry roads it was not built for. Death Valley in particular has stretches with no services for 50 miles or more, and the gas that is available inside the park, at Furnace Creek and Stovepipe Wells, runs well above outside prices, so top off in Beatty or Pahrump before you drop in. Rental contracts also prohibit off-road driving, so the graded dirt roads to spots like the Racetrack are technically off-limits and definitely uninsured if you damage the car out there. For the desert weekend itself, our Joshua Tree weekend guide covers where those long fuel-free stretches are.
A Few Booking Tips
Reserve early for peak season and reprice as your trip nears, since rates float and many bookings let you cancel free and rebook if the price drops. Consider off-airport neighborhood locations, which sometimes skip the concession fees, though they trade convenience for savings. Peer-to-peer options like Turo can undercut the big companies and offer cars the majors do not, but read the fine print on mileage caps and the host’s own insurance, because those deals work differently from a traditional counter. For a Highway 1 or wine-country trip, a smaller car handles the tight coast roads and parking better than an SUV; for a winter Sierra trip, size up to AWD instead. Skip the counter GPS add-on, which bills a daily fee for what your phone already does, and just download offline Google Maps for the stretches where service drops. And build in more time than the map suggests: Los Angeles to San Diego is about 2 hours without traffic and a lot longer with it, and San Francisco to Los Angeles is about 6 hours on Interstate 5 or 9 to 10 hours if you take the coast.
