When to visit
The most popular (and best) time to visit California Wine Country is during harvest season, which starts in August and ends in October. This time of year, you can enjoy pleasant temps, harvest events, and picturesque fall foliage—but be prepared for peak crowds and costly accommodation.
To enjoy favorable weather without the crowds, aim to visit Napa and Sonoma in April or May when the wine region springs to life with blooming flowers and budding grapevines. If you’re traveling on a budget and don’t mind chilly weather, consider planning your trip between December and February.
Getting around
Exploring Napa and Sonoma is best with a car, as you can tour all the wineries, tasting rooms, and towns according to your own schedule. However, if you want to visit the vineyards without a designated driver, there are other options. There are guided wine tours that will take you around Napa and Sonoma by bus, bike, trolley, and even limousine, although you can rent your own bike to explore the rolling vineyards at a more leisurely pace.
Or hop aboard the Napa Valley Wine Train, which takes you on a 36-mile (58-kilometer) round-trip excursion to and from St. Helena, stopping at wineries along the way. Public transport is limited, but buses run along major thoroughfares on a restricted timetable.
Traveler tips
While you might have come for the wine, you should leave time to take in and explore the beautiful scenery around the region, which has a number of state parks where you can hike, bike, and kayak. Visit Armstrong Redwoods State Natural Reserve or Sonoma Coast State Park near Sonoma, or Bothe-Napa Valley State Park or Skyline Wilderness Park near Napa for your nature fix in between wine tastings.
