Choose a smaller ride: Compacts and midsize cars fit Bay Area parking spots and cost less than the SUVs everyone grabs for summer wine trips.

What documents do I need to rent a car in Walnut Creek?
You'll need a valid driver's license and a major credit card in your name. The rental counter usually won't ask for proof of insurance. If you have your own car insurance or your credit card covers you, you can say no to the rental company's insurance. But you should be ready to show proof if they ask. If you're visiting from another country, you can use your foreign license. An International Driving Permit is a good idea and some rental companies may ask for one if your license isn't in English.
Is Walnut Creek a good base for exploring Northern California?
Yes. Walnut Creek is in a central East Bay spot, so you can easily get to San Francisco, Napa Valley, Sacramento and coastal areas. It's right where several highways meet, making it a great place to start your drives around the region.
How do the BART trains work with rental cars?
You can try a mix of both. Rent a car in Walnut Creek but use the BART train for day trips to San Francisco. This helps you avoid the city's high parking costs and traffic. You can park at the Walnut Creek BART station or you can leave your rental car at your hotel and walk or use a rideshare to get to the station.
What's the best vehicle type for exploring from Walnut Creek?
For most driving in the Bay Area, a compact or mid-size car works well. If you're heading to wine country, a convertible can make the trip more fun. If you plan to visit Mt. Diablo or other hilly parks, an SUV will give you more power for the hills.
Are there any seasonal driving concerns in Walnut Creek?
In summer (June–September), temperatures can get over 90 °F, so you should make sure the A/C in your rental car works well. In winter (November–March), it often rains, which can make roads slick, especially after it's been dry for a while. Snow is rare in the city but sometimes you'll see a light dusting on top of Mt. Diablo.
How do toll bridges and express lanes work with rental cars?
Bridges and express lanes in the Bay Area collect tolls electronically. You can use the rental company's toll program. Another option is to set up a short-term FasTrak account using a one-time payment or your license plate and then pay online within 48 hours. If you don't pay the toll, the rental company will charge you for it, plus a service fee.
