Best Times to Visit Napa Valley

The best time to visit Napa is August through October or March through May. Napa's peak tourist season corresponds with the region's harvest season (August through October). During this busy time, expect crowds and high prices for just about everything, especially accommodations. If you catch the tail end of the harvest season, you'll enjoy the area's beautiful autumn weather, complete with changing leaves and the chance of lower hotel rates. March through May, when spring is in full bloom and the summer rush has yet to arrive, is another prime time to visit. If you're looking to save a few bucks and don't mind chillier weather, a trip between December and February will likely be less crowded and more affordable. Plus, there's a number of food festivals that take place during this time, including the Napa Truffle Festival. Regardless of when you plan your Napa vacation, you'll find plenty to do, as wineries don't experience seasonal closures and festivals are held year-round.
