Grab your bags, stroll out of Santa Rosa, CA Airport (STS-Sonoma County), and pick up your rental car. Which one you grab the keys to depends on where you’re headed. If you’ll be mostly driving in downtown Santa Rosa, around 7 miles from the terminal, opt for something small. A compact car that’s easy to operate will suit those busy city streets. But with loads of things to see, like the picturesque sandy shores of the surrounding region, you’ll probably be clocking up a few miles. A bigger vehicle, like a full-size car or an SUV, will make lengthier road trips a joy.
